The China Study Myth

Flaws in the Vegan Bible

Read this article in: Portuguese

The year 2006 marked an event that rocked the world of nutrition (as well as the walls of Whole Foods): the release of The China Study by T. Colin Campbell. Printed by a small publishing company known for other scientific masterpieces such as The Psychology of the Simpsons and You Do Not Talk About Fight Club, Campbell’s book quickly hit the word-of-mouth circuit and skyrocketed towards bestseller status, with sales exceeding half a million copies to date.

The premise is that all animal foods—ranging from Chicken McNuggets to a fillet of wild-caught salmon—are responsible for modern ailments like heart disease and cancer. Such diseases, the book claims, can generally be prevented or even cured by shunning animal products and eating a diet of whole, unprocessed plant foods instead.

Although this startling thesis was hard for some to swallow, the book appeared credible due to its exhaustive references and the author’s laundry list of credentials—including a PhD from Cornell, authorship of over three hundred scientific papers, and decades of direct research experience. Perhaps not surprisingly, The China Study was quickly absorbed into the vegan community as a bible of sorts—the final word on the harmfulness of animal foods, and indisputable proof that a plant-only diet is best for mankind. To the exasperation of meat lovers everywhere (especially those who enjoy arguing for sport), once lively debates with vegans were now extinguished with one simple phrase: Just read The China Study!

But despite the book’s black-and-white declarations about animal products—and its seemingly well-referenced arguments—The China Study is not a work of scientific vigor. As we’ll see in this article, the book’s most widely repeated claims, particularly involving Campbell’s cancer research and the results of the China-Cornell-Oxford Project, are victims of selection bias, cherry picking, and woefully misrepresented data.

Does Animal Protein Cause Cancer?

The seeds of animal-food doubt were first planted early in Campbell’s career, while he was working in the Philippines on a project to help combat malnutrition. A colleague informed him of a startling trend: liver cancer was plaguing affluent Filipinos at a much higher rate than their less-wealthy counterparts—a phenomenon that, despite a slew of other lifestyle differences, Campbell believed was linked to their higher intake of animal protein.1 Bolstering his suspicions, Campbell also learned of a recent study from India showing that a high protein intake spurred liver cancer in rats, while a low protein intake seemed to prevent it.2 Intrigued by this gem of little-known research, Campbell decided to investigate the role of nutrition in cancer growth himself—an endeavor that ended up lasting several decades and producing over one hundred publications (none of which pertained to Fight Club).3

The China Study relayed Campbell’s findings with powerful simplicity. In a series of experiments, Campbell and his team exposed rats to very high levels of aflatoxin—a carcinogen produced by mold that grows on peanuts and corn—and then fed them a diet containing varying levels of the milk protein casein. In study after study, the rats eating only 5 percent of their total calories as casein remained tumor-free, while the rats eating 20 percent of their calories as casein developed abnormal growths that marked the beginning of liver cancer. As Campbell described, he could control cancer in those rodents “like flipping a light switch on and off,” simply by altering the amount of casein they consumed.4

Despite these provocative findings, Campbell wasn’t ready to declare all protein a threat to public health and stamp the peanut butter aisle with Mr. Yuk stickers. Animal protein, it turned out, seemed to be uniquely villainous. In several of his experiments, when the aflatoxin-exposed rats were fed wheat protein or soy protein in place of casein, they didn’t develop any cancer—even at the 20 percent level that proved so detrimental with casein.5 It seemed that those plant proteins were not only PETA-approved, but also the least likely to turn rat livers into tumor factories.

These findings led Campbell to his firm and famous conclusion: that all animal protein—but not plant protein—could uniquely promote cancer growth. Out with the steak, in with the tofu! But as several critics have pointed out,6,7 that proclamation required a few somersaults of logic (and maybe some cartwheels of delusion). The effects of casein—particularly isolated casein, separated from other components of dairy that often work synergistically—can’t be generalized to all forms of milk protein, much less all forms of animal protein. An impressive number of studies shows that the other major milk protein, whey, consistently suppresses tumor growth rather than promoting it, likely due to its ability to raise glutathione levels.8,9 Another of Campbell’s own studies suggests that fish protein acts as a cancer-promoter when paired with corn oil, but not when paired with fish oil—highlighting the importance of dietary context (and the neverending terribleness of vegetable oils).10

And the kicker: one of Campbell’s most relevant experiments—which sadly received no mention in The China Study—showed that when wheat gluten is supplemented with lysine to make a complete protein, it behaves exactly like casein to promote tumor growth.11 This means that animal protein doesn’t have some mystical ability to spur cancer by mere virtue of its origin in a sentient creature—just that a full spectrum of amino acids provide the right building blocks for growth, whether it be of malignant cells or healthy ones. And as any vegan who’s been asked “Where do you get your protein?” for the eight hundredth time will answer, even a plant-only diet supplies complete protein through various mixtures of legumes, grains, nuts, vegetables, and other approved vegan fare. Theoretically, a meal of rice and beans would provide the same so-called cancer-promoting amino acids that animal protein does. Indeed, Campbell’s experiments lose their relevance in the context of a normal, real-world diet opposed to the purified menu of casein, sugar, and corn oil his rats received.

But that’s only the tip of the proteinaceous iceberg. In his September 2010 article, “The Curious Case of Campbell’s Rats,”12 Chris Masterjohn ventured beyond the well lit pages of The China Study to explore the dark alleys of Campbell’s publications firsthand. And what he found regarding the low-protein rats was a far cry from the sunshine-and-lollipops descriptions we read in the book. Although rats consuming a high-casein diet were indeed developing liver cancer as Campbell described, the ones in the low-casein groups—which were portrayed as downright bright-eyed and shiny-coated in The China Study—were suffering an even worse fate. Campbell’s research actually showed that a low-protein diet increases the acute toxicity of aflatoxin, resulting in cell genocide and premature death. Because protein deficiency prevents the liver from successfully doing its detoxifying duties, less aflatoxin gets converted into cancer-causing metabolites, but the end result is massive (and eventually deadly) tissue damage.

Even the research from India that jump-started Campbell’s interest in the diet-cancer link showed that rats on a low-casein diet were dying with disturbing frequency, while the high-protein rats—tumored as they may have been—were at least staying alive.13 (It’s surprising, then, that The China Study promotes a plant-based diet to prevent cancer, when death is equally effective and requires fewer shopping trips.)

More clues for understanding the casein-cancer research come from another Indian study—this one published in the late 1980s, and examining the effects of protein in aflatoxin-exposed monkeys instead of rats.14 As with Campbell’s experiments, the monkeys were fed diets containing either 5 percent or 20 percent casein, but with one important difference: instead of being slammed with an astronomically (and unrealistically) high dose of aflatoxin, the monkeys were exposed to lower, daily doses—mimicking a real-world situation where aflatoxin is consumed frequently in small amounts from contaminated foods. In a fabulous case of scientific switcheroo, this study showed that it was the low-protein monkeys who got cancer, while the high-protein monkeys rejoiced in their tumorlessness.

This apparent paradox highlights a major problem in Campbell’s rat research: the level of aflatoxin exposure plays a critical role in how protein affects cancer growth. When the aflatoxin dose is sky high, animals eating a low-protein diet don’t get cancer because their cells are too busy dying en masse, while animals eating a higher protein diet are still consuming enough dietary building blocks for the growth of cells—whether healthy or cancerous. When the aflatoxin dose is more moderate, animals eating a low-protein diet develop cancer while their higher-protein counterparts remain in mighty fine health.

In a nutshell, the animal protein fear-mongering in The China Study stems from wildly misconstrued science. What Campbell’s rat experiments really showed wasn’t that animal protein is a vengeful macronutrient of doom, but the following:

1. High-quality protein promotes cell growth no matter where it comes from;

2. Protein deficiency thwarts the liver’s ability to detoxify dangerous substances; and

3. With more realistic doses of aflatoxin, protein is actually tremendously protective against cancer, while protein-restricted diets prove harmful.

Did the Real China Study Show That Animal Foods Are Associated With Disease?

The China Study only devotes one chapter to its namesake study, but that doesn’t mean it’s not a doozy. Also known as the China-Cornell- Oxford Project, the China Study was an enormous epidemiological endeavor exploring diet and disease patterns in rural China—a project coined “the Prix of epidemiology” by the New York Times. Spanning sixty-five counties and collecting data on a whopping three hundred sixty-seven variables, it generated over eight thousand statistically significant correlations between nutrition, lifestyle factors and a variety of diseases.15

Although a project of such magnitude inevitably found some contradictory and non-causal links, Campbell asserts in his book that the data generally pointed in one direction: “People who ate the most animal-based foods got the most chronic disease,” and “People who ate the most plant-based foods were the healthiest and tended to avoid chronic disease.”16 Although—as echoes through the hearts of statisticians everywhere— correlation doesn’t equal causation, these associations in conjunction with Campbell’s other research are supposed to make a compelling case for animal foods being legitimately harmful.

But were the results of the China Study really a sparkling endorsement for plant-based eating?

It seems this conclusion is based, in large part, on unreliable blood variables rather than actual foods. In his book, Campbell states that he and his research team “found that one of the strongest predictors of Western diseases was blood cholesterol,”17 and proceeds to treat cholesterol as a proxy for animal food consumption. Throughout this chapter, we learn that the China Study data found associations between cholesterol and many cancers, as well as cholesterol and animal protein intake—implying that animal protein and those same cancers must themselves be intimately linked.

But because blood cholesterol can be affected by a number of non-dietary factors and can even rise or fall as a result of disease, examining the relationship between food itself and health outcomes is likely to be more informative than using cholesterol as an overworked, fickle middleman. But the direct relationship between animal protein and diseases isn’t discussed in The China Study for one monumental reason: that relationship doesn’t exist. An examination of the original China Study data shows virtually no statistically significant correlation between any type of cancer and animal protein intake.18 Only fish protein correlates positively, but probably non-causally, with a small number of cancers: nasopharyngeal cancer, a rare disease that only strikes one out of every seven million people; liver cancer, which shows up in fish-eating regions because aflatoxin proliferates in humid areas near water; and leukemia, which is likely linked to other elements of the industrialized lifestyles associated with coastal regions (and thus fish consumption) in the China Study.19

Ironically, when we look at plant protein— which The China Study argues so vigorously is cancer-protective—we find almost three times as many positive correlations with various cancers as we do with animal protein, including colon cancer, rectal cancer, and esophageal cancer.20 Likewise, for heart disease and stroke, plant protein has a positive correlation while animal protein and fish protein have negative or nearly neutral correlations—meaning the animal-food eaters in rural China, if anything, are getting less cardiovascular disease than their more vegetarian friends.

But matters get even more interesting when we look at some of the peer-reviewed papers generated by the China Study data, most of which are co-authored by Campbell himself. As with the casein research, the China Study findings as described in Campbell’s book are a hop, skip, and eighteen thousand jumps away from what the original research says. Although wheat gets nary a mention in the China Study chapter, Campbell actually found that wheat consumption—in stark contrast to rice—was powerfully associated with higher insulin levels, higher triglycerides, coronary heart disease, stroke and hypertensive heart disease within the China Study data—far more so than any other food.21,22 Likewise, in a paper from 1990, Campbell conceded that “neither plasma total cholesterol nor LDL cholesterol was associated with cardiovascular disease” in the China Study data, and that “geographical differences in cardiovascular disease mortality within China are caused primarily by factors other than dietary or plasma cholesterol”—revealing that not even the beloved cholesterol middleman could live up to its heart-disease-causing accusations. 23

And in the spirit of saving the best for last, another of Campbell’s own papers, published a mere two years before The China Study hit the shelves, states point-blank that—despite Campbell’s claims about the superior health of the near-vegan rural Chinese—“it is the largely vegetarian, inland communities who have the greatest all risk mortalities and morbidities and who have the lowest LDL cholesterols.”24 Maybe the lesson here is the same one we gleaned from Campbell’s rats: it’s pretty tough to get sick when you’re dead!

The Gist

Despite its increasing popularity (and glowing endorsements by high-profile vegan converts like Bill Clinton), The China Study is, in many ways, more a work of fiction than a nutritional holy grail. The book has spawned a number of myths about the hazards of animal protein and the true results of the China Study itself—myths that easily crumble under a scrutinizing eye, but nonetheless continue trickling into the mainstream and gaining mounting publicity.

If there’s anything positive to take away from the book’s four hundred seventeen pages, it’s the promotion of a whole-food diet—and the resulting elimination of vegetable oils, high fructose corn syrup, refined grains, and other industrial products that tend to displace real food on our modern menus. But for those seeking scientific literature of a higher caliber, The Psychology of the Simpsons is likely to be a more satisfying (and animal-product-friendly) read.

Getting rid of empty and refined foods, especially vegetable oils—the common denominator in all these plant-based prescriptions—will make for improvements in almost everyone. But long term, without nutrient-dense animal foods,
deficiencies will emerge.

63 Responses to The China Study Myth

  1. cate says:

    What’s the truth?
    I’m puzzled by the conflicting information everywhere I turn re plant-based diet and consumption of animal products. I have read the China Study and agree that it seems extreme and wonder, also, about the science. Large studies like this can be interpreted in a variety of ways , some good, some not so good. I also subscribe the the WAPF philosophy. Sadly, especially as reflected by this article, the dialogue seems to be divided into teams, each having their own studies/science to support their point of view and a need to be right. This article would have been improved by less put-down of the other side and sticking to the facts as she see them. The somewhat snotty tone makes it sound like she has her own ax to grind.

    • Misnomer says:

      To Cate: More like Dr. Campbell has a vegan propaganda to spread. I believe any person with a brain for analysis and an intolerance for bull-crap would grind their ax on Dr. Campbell’s work.

    • PlantsRule says:

      I also have trouble determining what is healthy and what is not because one day something is healthy and the next it give you cancer. The problem I find with a lot of the people trying to debunk Dr. Campbell’s China Study is that many of them are not as qualified as Dr. Campbell. Perhaps I missed it in the article above, but I do not see Denise’s credentials. I myself am not an expert in statistics, but I know that its not as simple as correlating two items together. It is much more than that. You must account for variables and things of that sort, which Dr. Campbell did in his book. Also, his book is not one study, it is a compilation of many studies and experiments that all lead him to the same conclusion over his career.

      The other thing that I do not see being mentioned in any of these anti-China Study write ups is the work of Dr. Essylsten. When switched to a plant based whole foods diet, his patients heart disease reversed, arteries became less clogged, they reduced the amount of medication they needed to take, and this all worked to the point where they no longer needed expensive and dangerous heart surgeries.

      This is why I have to side with the scientist who has a lifetime of work to back his claims.

    • Kevin Morang says:

      I agree totally with Cate, and am in the same boat, dizzied by endless studies PROVING that this position or that is correct. As an non-scientific person that just wants to figure out how to live and eat healthy in my twilight years, I am getting weary of trying to figure out who is right. #tiredandfrustrated!


    • Brian says:

      Sadly we can’t trust anyone these days. Too much hidden money involved. Could Campbell have been influenced by money from vegan groups? Was Minger influenced by dairy or meat groups to counteract the effect of The China Study. We may never know. We are left with our own sound reasoning skills which too will be influenced by our own preconceptions. Eat as cleanly as you possibly can, avoiding as much chemical adulteration of your food chain as you can, maybe even grow as much as you can of your own food both plant and animal. This is about the best we can truly do and much of the rest is really up to chance since you really can’t control the innumerable number of variables that may or may not cause cancer. Oddly enough, there seems to be significant support for , and I haven’t heard any argument against the idea that stress in many forms including worrying about diet can be very bad for your health with possible connections to cancer via free radicals and chemistry changes in the body. So worrying about your diet too much can be doing more harm than your diet itself. It really is a personal decision. I personally am practically vegan in that I still eat meat occasionally. I started due to things like “Forks Over Knives” and “The China Study” but am staying the course because of very real changes I am noticing within my body and how I feel while eating a vegan diet. I am sure others will claim the same with a meat based diet as well. I am / was Asthmatic, COPD, Diabetic, Morbidly Obese, Hypertensive, and several other issues most of which have seen definite improvement since I began leaning toward a more vegan centric diet. If you make changes to your diet pay close attention to your body and how you feel and let it guide you within reason.

      • Lee says:

        I appreciated your comment. You express, I think, what we all feel – exhaustion about trying to weed through all the research and position points, and come to an unbiased assessment of what would be a good diet. The only thing I would add is this – Dr. Campbell probably profited greatly from his book (unless he dedicated the proceeds to a charity or something). But, he a highly educated and presumably well-paid man over the past many years, and it is easier to trust such a person than the massive industries whose interests are threatened greatly by what he is saying. On a balance, I’ll trust the whistleblower over the industry that makes trillions and has the most to lose… This is especially true because Dr. Campbell does not sell any nutritional supplements etc – one person could read his book, adn then just summarize the whole thing to a friend: “Eat fruits, veggies, and whole grains”. All other authors have follow up books, diets, a brand of vitamin they recommend, etc.. but not Dr. Campbell, to my knowledge…. which tends to lend some further credibility to his name.

  2. Randy says:

    Was there a motivation for Mr Campbell to arrive at these conclusions and publish them? Your article seems to imply that these conclusions should have been obviously incorrect and makes one wonder why someone with his knowledge and skill sets and apparent passion would knowingly mislead on a life and death topic??

  3. John Hristov says:

    personal experience
    I think one doesn’t need to argue, but just try it. I lost 40 kg of weight and started to run marathons and ultras since I went on a plant diet. Friends and relatives, including my wife, two of my brothers, my mother-in-law and my children demonstrate drastically improved or superior health when moved to plant diet. So, if you feel good on meat, go your way, but I know the huge difference it made for me and prefer the other way.

    So, as I said, it is easy. If you are corpse eater, try plant for a couple of months and make your mind. If you are veggie, try meat for a couple of months and decide (BTW I have a friend also, who was vegan for 15 years, and at the age of 28 (yes, she started vegan very early, her own decision) suddenly started to eat flesh. She told me she didn’t know why and she had no apparent reason.

  4. Liz says:

    I’d have to agree….
    …with the commentator John H. To each their own. Constantly, as Cate says in her comment, something is good for you and bad for you depending on who you ask. I just try things for myself. My body chemistry is different than yours so what works for me may not work for you. Therefore both the China Study and the above criticism must be taken with a grain of salt.

    For me it just so happens that a plant based partially raw diet (I also eat eggs and honey) is right for my body. My skin is clear, my nails are strong, I am energetic, my hair has less breakage, my cycles are less painful, my mood stays steady, I feel great after I eat, and I have even noticed less body odors smilies/grin.gif . (Sorry if TMI for anyone but we are on a healing arts domain.) With that said, my husband is the exact opposite and needs high protein to function at his best ability. Thus my opinion – “different strokes for different folks.”

  5. Margaret Robin says:

    Comments seem right on, article, not so much
    Ah – The China Study is sensationalized. That jumps out at the reader if you get to about the second third of the book. Unfortunately, this article is also sensationalized. What is a body to do? I could try to read the original research findings myself, but probably would be lost in medical vocabulary. I like the commentators here who do what they feel is right and do what works for them. The vegan diet works for me very well. I do supplement occasionally with brewers yeast, which might not be pure vegan?

  6. Timothy Wong says:

    person observation
    I personally have experience with the vegan diet, i never thought i can be a vegan but after watching forks over knife I was very impressed by the strong facts that support the benefits of vegan diet, but it’s not easy as meat does taste good and you do have more choices when you go eat out, and if you don’t live in SF, NYC, or bigger cities, it’s hard to find soy milk..they would be staring at you, like are you crazy? Anyway, my partner and his whole family has always been having high blood pressure issue, and his father and his uncle died fairly young because of a heart attack, he has been on a vegan diet for almost a year now, his blood pressure is back to normal, from 150/100 to 115/70, he was so shocked by that as he didn’t take any medication at all, that reinforce the idea that he should stick with his diet.
    I am here to say it may not work for everyone for having this very strict diet, but it definitely has some very powerful benefits considering our modern days diet essentially are very much processed and sugar packed. While not everyone who are animal eater would die young, but I strongly recommend the plant based diet is a healthier diet, my current diet consists of 80 to 90% of vegetables and whole grains, and the rest would be white meat and fish. No more red meat.

  7. Michael Ryan says:

    The commentary here does have a concensus: this article does not make the point it promises to make.
    The author, Denise Minger, starts her critique of “The China Study,” by asserting, “the book’s most widely repeated claims, particularly involving Campbell’s cancer research and the results of the China-Cornell-Oxford Project, are victims of selection bias, cherry picking, and woefully misrepresented data. She then goes on to make this case with exactly that.

    One need not be a scientist to know who is right. Two phrases in the article give it away: “meat lovers” and “PETA-approved.” The first is irrelevant in the search for scientific truth (food addictions are also well-documented) and the second is a sarcastic swipe at those who are drawn to veganism for moral reasons (as opposed to dietary-health alone).

    The useful parts of this page are within the reader comments, almost all of whom take issue with the article’s intention. I agree wholeheartedly with those who suggest that each individual must make up his or her own mind, about what is healthy for them, and what is not. I would also agree that the evidence of the benefits in a vegan diet (not to mention an even stricter regimen without processed foods, and without added salt, oil or sugar) is overwhelming. Just look at Bill Clinton (or would his being a liberal offend the meat-eating crowd?)

  8. Omnivore Searching says:

    Points taken
    The writer in this article definitely brings up very valid points about the selective reporting of research from The China Study. I am reading The China Study now and already and dubious about the simplicity and lack of follow-through on other cancer and illness factors, including other non-animal based foods, like wheat and corn for example. I am open to reading and learning what I can from this book, though today when reading another critique about the book I saw some quotes from the book that are really factually incorrect (which I even know). Campbell doesn’t know the difference between simple and complex carbohydrates, which for a nutrition scientist with decades of experience, is alarming. This leads me to wonder if our specialized nutritionists, though perhaps too broad to categorize, are really knowledgeable about health and vitality.

  9. Barcadero says:

    Caveat lector
    1. The Weston A. Price Foundation is funded by meat and fish producers.
    2. The China study was funded by universities and the Chinese government.
    3. This article does not address IGF-1.
    4. This article uses a rat study as a straw man for the population study.
    5. The data shows: whole-food plant-based diets reverses the top killers.
    6. The final quote is taken out of context. The inlanders were DHA deficient. Cancer was omitted, except liver cancer, which was positively correlated. Plant-based alternatives were shown to be as affective as DHA at deterring chronic diseases. Omega-3s from land animals (pigs, cows, etc.) were shown to not lower mortality or morbidity like DHA. Upshot: Some fish, or better yet, algae to avoid mercury concentration, is a good thing!
    7. Minger uses subjective language and ad hominem attacks. Nevertheless, she is a confident public speaker and arguably attractive, and thus many take her advice.
    8. Taking nutrition advice from paleontology …

  10. Eric says:

    What is truth
    I will side with the evidence….I have not seen nor heard of one instance where this data has been discounted. Only weak attempts at smashing the good news and information these scientists have PROVEN over and over and over again. To me, much of this starts and ends with the government organizations that “oversee” what it is that “we” need. What a pile of crap. These agencies are as corrupt as the administration. Really, it doesnt take a doctor to understand that the former CEO or board member of the Dairy Association should be making decisions as to what “we” need to have in our diet, and then no shock when there is an increase from 1 to 2 cups of “milk”. Get real people, we are being sold out to profit for companies that produce dairy and meat….if “anyone” was REALLY concerned about US, many practices would cease when it comes to animals….but NO ONE really cares about us….all dollars and cents. Look at Al “the idiot” Gore who curses those who drive SUV’s, and then hops in a private jet….wake up.

  11. debve says:

    too much focus on the protien. a skewed and slanted perspetive.
    hey you love to eat dead critters go for it. don’t try to justify it with documentation provided by the beef producers of america. there have been plenty of studies aside from this one that say basically the same thing. what about saturated fats, uric acid ect. it isn’t necessarily the protien itself it is the entire package. she even goes so far as to call it fiction.

  12. DeAngela Osborne says:

    sucking on a cow teat is just plain creepy
    What about WebMD or Harvard School of Public Health, are they credible sources? They seem to think that dairy products are not needed for health benefits. Additionally, Harvard School of Public Health believes milk recommendations are a “step in the wrong direction.”

    The Dairy Industry has done an outstanding job having us believe that we still need to suck on the teats of another species, it’s pretty gross really. Put it on our TV, have a celebrity endorse it, pay a few people off, tell us we need it, spend zillions on propaganda ads, and it could have been a dog. I’m no doctor, but this guy is. In fact, dairy was removed from “the healthy plate” by the Harvard School of Public Health a while back, not sure if everybody knew that or not.

    Walter Willett, MD, PhD, professor of epidemiology and head of the nutrition department at the Harvard School of Public Health says, “One of the main arguments for USDA recommendations is that drinking milk or equivalent dairy products will reduce the risk of fractures. But in fact there’s very little evidence that milk consumption is associated with reduced fractures,” Willett tells WebMD.

    Furthermore it’s linked to most of our common “manageable” diseases at this stage.

    Brevity, please. I’m working on my diet, and trying to learn all the time. So naturally, what Denise Minger has to say is of interest to me. However, I wish she would stop tryng to sound so cute in her writing style. It doubles the number of words one has to get through, and just gets tiresome. There is way too much on the internet to read to slog through it.

    Wheat is already a complete protein
    LOL, it is the ratio what can be different to animal foods. Failed critic at this regard.

    Most plants are complete proteins, no missing aminoacids there.

  15. It’s just mean to bash vegan doctors and its meaner to slaughter, TORTURE, tens of billions of sentient beings for unnecessary flesh foods. It is really telling that our society is so rampant with predatory acts of violence when all it does is cannibalize its own young by teaching them to be predators, starting with their plates.
    NO WONDER the violence comes full circle. There are MORE Reasons NOT to consume sentient animals than economics or self gratification. Perhaps ALL your family members should work in a pig or calf slaughterhouse for a month! Or a chicken slaughter house where BABY birds are tortured to death after a life of trauma and stress. And this we call “FOOD?” OMG. The PROOF is in the fact that patients of many doctors using plant based nurtition as MEDICINE ARE Being cured and reducing medications or eliminating them, is PROOF enough. WATCH. What humanity does to other beings is abnormal and unholy. One reasoned look at our culture and we see the symptoms of our mindless violence to defenseless creatures. Is eating flesh and dairy really worth the death of our planet because that IS what’s happening….

  16. KathyBaja says:

    what’s lacking in The China Study and this commentary is the importance of sufficient protein….
    0.5 to 1.5 grams per pound of body weight a day, depending on your level of activity. So even for anorexic vegans, that’s at least 50 grams per day.

    Vegans can claim carrots and other veggies have sufficient protein. One large carrot has about 0.7 grams of protein. Go ahead, vegans, take all day to consume 100 carrots and you’ll get 70 grams. and have fun trying to find the rest of your MDR of protein in lettuce etc. Try Beans and Nuts instead, but it will still be a challenge to meet your protein MDR, unless you try a protein supplement like Medi-Clear. I make a smoothie using it every morning and get 32 grams of vegan protein, with only 1 gram of sugar. And I can run circles around the vegans and vegetarians I know.

    Vegans argue that we really don’t need that much protein. If so, why did my friend Kat’s gastrocnemius muscle begin to repair immediately after increasing her protein consumption from 15 grams a day to nearly 50 grams, while she suffered for 5 months before that with no improvement? why did another vegan who claims he gets enough protein from veggies have DOUBLE HERNIA surgery recently? Do you know how rare that condition is? Our abdominal muscle is incredibly strong, very hard to injure, since it encloses all our abdominal organs and supports our back muscles. But his body was apparently stealing protein from his abs, which tore, with the resultant protrusion of his intestines.


    Vegans also tout Olympic athlete Carl Lewis, who turmed vegan in 1991. Before going vegan, Lewis consistently dominated both sprinting and the long jump. After the heights reached in 1991, only 1 year after starting the vegan diet, Lewis started to lose his dominance in both the sprints and the long jump, and in 1992 failed to compete in events where he was formerly strong.

    I hear story after story from vegans and non-vegans about problems with healing injuried muscle tissues, chronic back pain, and overweight (chronic hunger!) among vegans and vegetarians. Most are so busy patting themselves on the back about saving the world by not consuming those poor “helpless” creatures, they don’t think twice about their own health. There are lots of ways to save the world. If you vegans and vegetarians want to promote the health of the world, over which you have little control, over your own health, go for it, just stop preaching to the rest of us. I was a vegetarian for 20 years and am far more healthy and thinner now that I eat a little meat every week.

    finally, I’m a biologist. We have teeth called CANINES. They didn’t get there by accident.

      And not to mention when I was closely vegan I had 2 miscarriages, once I started consuming more protein I was able to get pregnant and carry the baby just fine.

      “When the debate is lost, slander becomes the tool of the loser.” – Socrates

      “0.5 to 1.5 grams per pound of body weight a day, depending on your level of activity. So even for anorexic vegans, that’s at least 50 grams per day.”

      If I look at a regular vegan day where I consume fruit, vegetables, and grains (ie. simply bananas, rice, and asparagus) I am consuming 3372 kcal and 57 grams of protein no problem. What the commenter neglects to realize is that a lot of vegans tend to eat much larger quantities than those that are not vegan. To put this into perspective I am a slender 140 lbs female at 5’8″ I rarely excercise which equals to 2.5 km of biking to work every week and I regularly consume 3000-4000 calories depending on my appetite.

      “Vegans also tout Olympic athlete Carl Lewis, who turmed vegan in 1991. Before going vegan, Lewis consistently dominated both sprinting and the long jump.

      This argument is irrelevant. It doesn’t account for the fact that in modern day sports popular use of performance enhancing drugs.

      This entire argument also neglects to point out how protein is absorbed and how much protein you need daily to absorb.


  17. food tales
    i’m a medical doctor and have seen personally how a plant based diet is clearly superior to a meat based diet. you can’t argue with clinical results and lab numbers. my patients with high cholesterol, blocked heart arteries, gout, diabetes, hypertension and other lifestyle related diseases have all improved or even reversed their conditions with the switch from an animal product based diet to a largely plant based diet. those who benefited most were those who went for a purely whole foods, plant based diet. i have no doubt that Dr. Campbell’s findings are credible and true. i find that people who have either personal interests in the meat and dairy industry or who simply have a preference for eating meat and meat products because it tastes good and they feel they cannot live without it are the ones determined to put down people like Dr. Campbell who’s interest is for the good health of the public.

    Protein Myth
    This is in response to CathyBaja, are you serious? Obviously you do not know your nutrition AT ALL!!!! Did you realize that 1 cup of black beans has 15 grams of protein, that is 1 CUP!! Nuts, grains, tofu all have tons of protein. 1 cup of cooked Quinoa has 18 grams of protein!!!! You are making claims that are completely false and making connections where none exist. You say that your vegetarian friend got a hernia and you say he got that because he was not getting enough protein. By your logic a person who eats meat should never get a hernia. BUT HOLY CRAP THEY DO!!!. Protein intake has nothing to do with hernias you are making connnections where none exist. As far as Carl Lewis, HE TURNED VEGAN IN 1990!!!! Look it up, he credits 1991 to his turning Vegan and even though in 1992 he got beat in some qualifiers in the olympics in 92 he turned in the fastest anchor leg ever in the 4 by 100m and that record stood until 1997. Also he won his 3rd gold medal in the long jump in 1996, long after turning Vegan. Plus if you are a biologist then you know that our digestive track mimics that of a herbivore. All of what you say has absolutely no merit. You can be a vegetarian and Vegan and be in bad health, that is if you are one of those vegans that eats French Fries and Potato chips and thinks that is okay. There is plenty of bad food for vegans but if you eat right you can be way healthier then any meat eater.

    Middle ground
    I think there definitely is a middle ground. From my experience counseling patients as a primary care physician, a whole foods diet generally holds promise for improving cardiovascular condition such as hypertension and general condition. The atkins type diet which is high in saturated fats is also beneficial for those trying to lose weight, and weight loss is one of the most important determinants of having a healthy blood pressure and vascular condition. I think the main point is that processed foods are always bad, and possibly by maintaining a healthy weight and keeping blood sugar and insulin levels down health can be achieved with or without a large component of animal protein.

    • Doug Dever says:

      Most intelligent comment on here….And from a doctor. Go figure.

      • jbort says:

        Low carb diets have been proven to be unsustainable in weight loss. There is tons of literature disproving the Atkins style low carb fad diets. Not to mention there are studies and a more famous meta-analysis that show a correlation with low carb diets and a higher overall mortality rate.

        Weight loss is easily achieved and more importantly sustained through a plant based diet.

        One more point, a US physician is only required 3 hours of nutrition education to earn their degree. I have no knowledge of whether or not this physician is from the USA, but I also have no reason to trust their knowledge over that of T Colin Campbell or really any other layperson who’se done the time and research on the topic. The truth is most physicians know just as much about nutrition as the average person.

It is still high however so now I am going to go meat and dairy free for 3 months and see what happens.

    Ever wonder why people are still smoking? Yes, there is money to be made. The Tobacco industry..yeah.
    Well, I am reading some of these comments, and some going in great length to discredit the China Study. READ IT FIRST.
    The biggest reason that it is not more widely known or promoted is this: The Meat Council, the Poulty Industry, The Pork industry ETC. Do you think they may have some MONIES pending on this study???? Its all about PROFIT folks.
    My friend who i thought was pretty fit, a body builder with maybe just a little too much bulk on him contracted prostate cancer. He ate ALOT of CHICKEN and broccoli. Probably up to 2 chicken breasts every night for a few years. Didn’t sound that bad. No red meat consumed. Bottom line, way too much protein consumed. These chicken breasts probably had growth promoting hormones in them too. Chicken breast of the 60’s 70’s were much smaller without these additives.
    Anyway, I digress, He has inoperable prostate cancer at this point.
    Personally I am sharing this book with everyone I know and care about. Most will go on with their current diets, it just easier, right…?
    My body, THANK GOD, has always refused to eat a lot of protein. Always made me feel kinda sick and heavy. I am 67. and told all the time how I look years younger.
    Do yourself a favor and read the China Study and figure it out for yourself. No cancer for me, thank you.
    PS obviously, goes without saying, eat Organic whenever possible.

      I cannot agree with you more Dianne, as a psychologist I just want to add that two primitive but potentially deadly defense mechanisms in the human psyche namely DENIAL and RATIONALIZATION can cost us our lives.

      We need to be pretty brainless if we are eating animal products which are pumped full of growth hormones and antibiotics sprayed to keep them from loosing its red attractive color, packed in plastic and washed in ammonia to get it fresh again for human consumption.

      But then some of us are so far into denial that DENIAL “is only a river in Egypt!!”

    Well, how very confusing when all I want to do is get well!
    I have read countless books over the years and tried many protocols and spent thousands of dollars all to no avail. A few points I have noticed are.

    1. Folks that change to a plant based diet do indeed improve their health, weight and look fresher and younger in the beginning.

    2. Over time it would appear that vegans develope some serious deficiencies.

    3. Heavily reliant meat eaters also develop health problems.

    Conclusion: eat a whole food plant based diet with some heathy fats and a little meat occasionally to keep the balance.

    What about almond milk? I tried it and found it to be a good alternative to whole milk or soy milk.

    In Colorado I found that all the little coffee shops offered almond milk. That doesn’t happen here in Texas.

    I am currently ready “The China Study”. I am finding it quite interesting.
    The doctor that I saw about my high blood pressure refered it to me. My blood pressure has come down a lot with this new way of eating for me. I still indulge on vacations, but overall I am thrilled to have this information.

  26. Joan B. says:

    I highly recommend reading The China Study, as well as other books written by the doctors mentioned in this article’s Sidebar: Plant-Based Diet Doctor Squad. (The only reading I would actually ignore is the sarcastic unscientific article, Flaws in the Vegan Bible.) After having heart bypass surgery and reading several of these books, I decided to go Vegan 3 years ago. As a result, after 10 years of meds, I am no longer diabetic, I reversed my severe heart disease to the almost-disbelief of my cardiologist; I no longer have high blood pressure, and don’t have any stomach ailments. I will say, in addition to going vegan I also eliminated added sugar and fats and only eat whole grains. Almost incidentally, I lost a lot of weight and gained a huge amount of energy. Was it hard? Actually no, once I realized how abundantly the earth provides. The food I’m eating now is so satisfying; the simpler the better. And I love knowing my food now comes from the earth and doesn’t involve the suffering or slaughter of any animals.

  28. Charles Brown says:


    Just finished reading “The China Study” after it was recommended by my older brother (a dentist) and his wife (a doctor). Like them, I have embraced and implemented the recommended dietary advice offered in the book (as well as the book, “My Beef With Meat.”

    I was only going to do the diet for 2 months max, if nothing ‘spectacular’ happened. Fast forward 2 months and not only am I still doing this “diet” but I have every intention of sticking with it – no problem – the rest of my life.

    …Why? Because even though I was already in great shape for a 55 year old and was eating what would otherwise be considered a ‘balanced diet,’ I’ve felt sooooo much better! I’ve doubled my running distance and I can sprint now – something I figured was permanently in my past. It’s been such an improvement that I actually wondered if something else was going on – but this is the only thing in my life I’ve changed (except for doing forefoot running instead of my heel-to-toe method I’d been using for 35 years).

    I have needed less sleep – because the sleep I do get is better quality – my joints feel better (which is probably why I can run so much farther. In fact I feel 20 years younger. And it’s true – I feel full sooner and don’t have the hunger for sugar and fatty foods like I had. (I never was a huge overeater, but I did love desserts and buttered bread and so forth.)

    It really has amazed me the difference. I could go on but it’s getting late. For me the proof is in the pudding. Nobody could convince me otherwise.

    And oh, almost forgot, there will always be naysayers for popular books on any subject – especially about diets and nutrition. The difference, however, is peer-reviewed and independently corroborated evidence by professionals who have done heaps of post-doctoral research and spent their whole lives trying to do what’s right to help people – vs the rest of us ‘normal folks’ ;-)

    …Anyway, it’s often us ‘normal folks’ who so often try to ‘debunk’ professionals without anywhere near the experience or education. (trying to be nice here to the author of the article/post I’m responding to ;-)


    • Doug Dever says:

      I am the same age and can do all you do, have low cholesterol, bp of 117/65, resting pulse of 55 and I eat meat. I don’t, however, eat processed foods especially carbs and the meat is free range and grass fed. An important thing to remember is that correlation does not prove causation. Even the best researchers fall into this trap.

  29. RJWenzel says:

    Charles, one doesn’t need to be any kind of an expert to use their own brain. The people debunking Campbell’s work are presenting solid evidence found right within his own work which shows that he’s been playing fast and loose with the data. And I might add that the interesting thing about Dr. Campbell’s work is that it HAS NOT been peer reviewed, and it lies in contention with several other studies done by equally esteemed and credentialed scientists, whose work actually HAS been peer reviewed. I would also add that Campbell made quite a lot of money on all of this and the people debunking don’t make a dime spending the time to point out his work’s deficiencies. So you might want to be careful talking about people who “spent their whole lives trying to do what’s right to help people” when you do not, in fact, know why any of the people involved did what they did.

    As for your own experiences, I’m glad to hear you’re doing well on the diet. As has been proven, a vegetarian diet clearly works for some people, and it clearly does not work for others. Reference this article

    The detractors are not claiming that it doesn’t work for anybody, they’re merely refuting Campbell’s claims that it DOES work for everybody, and they’re also refuting his wild claims about cancer – using Campbell’s own data against him. I can’t see how that would be a problem for anybody, unless they didn’t read the information presented or didn’t understand it.

  30. Daniel says:

    In all this debate the number one idea is strikingly over looked and there is still much truth and importance regarding whole-food plant based foods EVEN FOR MEAT EATERS, MICRO-NUTRIENTS. The fact is, point blank, Americans do not eat enough FRUITS and VEGETABLES (aside from vegans, vegetarians) PERIOD. You can listen to the milk farmers (who fund this organization, this site and there campaigns), the athletes, Mr. Gym-rat Douchebag, pharmaceutical companies who refute whole food plant based diets citing the all important necessity to include animal proteins in diet and that’s fine. We’re all familiar with these Arnold, Ronnie Coleman wannabees telling us that you need this amount and that amount of protein intake per pound for your body to “heal correctly” or the efficiently build muscle. Let’s clear up a few things. One, there are many athletes that thrive on plant based diets. Second, YES (Mr. Gym-rat Douchebag) animal proteins ARE, FOR CERTAIN, more efficient at building muscle and helping you recover. But lets talk about regular people. (not Arnold-Coleman wannabees)Regular people who do not pursue lifting heavier weights or are not looking to “get big” simply do not need those high levels of protein. And let me clarify, I DO EAT animal protein and am not a proponent or representative for either side of the “to meat, or not to meat?” debate. What I am saying simply is that people on both sides miss the big (or smaller) picture and overlook what they should be taking away form all of this. MICRO-NUTRIENTS. The China-Study is not focused entirely on the rat studies and the correlation between casein protein and tumor production, and one cannot focus entirely on that no matter what side of the fence you’re coming from or through what biases you read it. It also points to low cancer rates correlated to efficient intake of micro-nutrients, again MICRO-Nutrients. All this arguing about what are “appropriate” levels of macro-nutrients (carbs, fats, proteins) and what “feeds” or “starves” cancer cells is hogwash. If vegetarians don’t get enough “real” protein, then big meat eater, western diet eaters and body builders don’t get enough “real” micro-nutrients. I guess that the trade off isn’t it? But, it doesn’t have to be. The gym-rate who comes home from the gym eats a huge steak, a bunch of potatoes, and six small florets of broccoli is not getting enough vitamins and minerals. However, being that this is a societal issue, let’s not focus on Mr. Gym-rat Douchebag. Instead, lets focus on Americans as a population and the western (or American) diet and its correlation to “western disease.” This article pointed to the fact that inland people in China who ate some (FAR less than Americans) meat and still had low cancer rates. So what? Did the author really believe that claim debunks the China Study or the importance of fruits, vegetables and micro-nutrients. Those populations ate SMALL portions of meat INFREQUENTLY. In the documentary produced based on Campbell and Esselstyn, the filmmakers interview a Chinese man who developed heart disease and coronary artery issues only after indulging in the gluttonous American diet. In his interview, the man described the difference in PORTION SIZE (pay attention ‘Murrica) of meat or fish in his native land to that of portions in America. He said, very clearly, that the Average portion of meat consumed by a single person in the United States was large enough to be sliced and feed a family of FOUR PEOPLE in his native land. This difference is key (and totally overlooked by BOTH SIDES) to determining correlations between animal product consumption, chronic conditions, heart disease and cancer. Regardless of which interpretation you believe the concept of a cancer “light switch” regarding animal products is completely unreasonable. Perhaps, we should consider these correlations as being more of a dimmer rather than a light switch, with the focus being how bright one wants the room to be. If a person wants to be big like Arnold, they’ll need to eat lots of protein, preferably animal protein. If a persons competes in long distance runs regularly, they’ll need to eat more complex whole food carbohydrates. If a persons heart cries for the thousands of unfortunate critters raised for slaughter, they’ll be pressed by their conscious to eliminate animal products all together. These trade-off’s represent the adjusting of the “dimmer.” Diets high in animal protein “may” raise risks for cancer or health issues and diets omitting animal products “may” cause protein deficiencies and raise the risk for other disease/conditions. Most Americans today need adjust their diets somewhere in the middle, control portion size and limit the consumption of certain animal products, fats, fried and garbage foods. However, no matter where you adjust your dimmer you will still need electricity. Just like the current flowing through the dimmer switch, micro-nutrients will allow you to reach your maximum health potential no matter what levels you set you macro-nutrient intake at or where you food sources are from. In recent years some vegetable rebels in the medical field feel that they can cure cancer using only nutrition, while defenders of conventional medicine will make it clear that only the current medical practices can rid the body of cancers and others pathology. The saddening absurdity in all of it is that nutrition is seldom mentioned let alone being prescribed. Even the “super healthy” Mr. Gym-rat Douchebag only eats 1/10th the amount of nutrient rich foods he should be eating. The purpose of this response is to highlight the importance of vitamins and minerals, portion control and BALANCE with highlights being made regarding increasing fruit and vegetable intake. Let’s hope we all find a healthy balance.

  31. John Martin says:

    I’m a cattle rancher. I’ve eaten a lot of beef and chicken for most of my life. I’ve chosen not to side with the results of the China study because it will negatively affect my income and that of my family. It really doesn’t matter to me if a vegan diet is good for you and it makes you healthy. I’m more concerned with livelihood of folks like me, who depend on the sales of animal products for human consumption. If you get sick eating meat or vegetables, that’s not my problem, but your own problem. Why do we have doctors, hospitals and big pharma then? For one reason only, to get you back to health or at least to keep you alive for as long as you can get health care and you don’t die.

    As always, honesty trumps everything. If your livelihood doesn’t depend on the meat industry, then please keep eating meat. Meat is good for you…say who? I say so and that’s my final piece of advice. We have to die one way or another. Why not die eating something that you enjoy eating. Who wants to eat vegetables, nuts and fruits exclusively? I don’t, so shouldn’t you! The best doctor is the one doing the talking now: c’est moi. I’m of french descent, so I know a thing or two about food.

  32. Ralph says:

    I am writing this particularly for children and mothers. They should be eating ample protein and I would rather convert an excess into energy than come short on protein.

    As sources of energy/calories there are fats and carbohydrates. Carbohydrates that have significant calories are grains, root vegetables, beans and fruits, vegetables are typically lower in calories. Whole Grains, and beans are not a food you should be eating due to the anti-nutrients, difficult digestion and toxins. If you choose to do so, cook very long or use a pressure cooker for the high heat. Still I would keep them very limited, or avoid them altogether.

    I would not eat a low fat diet (less than 20% calories from fat) unless I understood the carbohydrates really well. In this sense, I believe fat in the diet also functions as a safety factor for mistakes in our knowledge and miscalculations.

    I suppose some say that if you eat vegan and do everything correctly, including supplementation, you can be quite healthy. However, I would suggest that animal products do offer a very large significant safety factor in case you were to miss something. Particular interest for many people would be Vitamin B-12 which is primarily found in red meat and fish, not even so much in poultry or dairy. That is not all by any means, just do not depend on poultry alone for meat.

    Many people do well when switching to vegan because they become hypo-caloric, which is great for your heath if you are overweight, but this can be deceptive if you are not.


  33. Edward Cummings says:

    I would argue that the industrial livestock farming systems are flooding the market with cheap, poor quality animal products which bad for human health (via nutrition and antibiotic resistance) and the environment. So go for higher welfare, organic, and pasture fed meat also you might want expand your choices beyond beef, pork, chicken and lamb.

  34. Bernabe Angeles says:

    Most, if not all, of our sources of animal protein come from herbivorous (vegetarian) animals like cows, sheep, deer, goat etc. Funny, these animals eat grass or leaves to make the protein that we get by eating them. And the probably largest animal (the elephant) eat nothing else but plant leaves. Where do they get their protein??

    Our teeth are so like those of the herbivorous animals – are we meant to be plant eaters too?

  35. Georgie says:

    Campbell is not vegan. He promotes a plant-based diet — not a vegan diet. (he suggests eating a little fish)
    I find it hysterical that a 24 yr old writer thinks she knows more than people who actually do the research. (so much easier to be a critic of someone’s else’s work when you do none of your own)
    By the way, having her mom feed her a veg diet does’t make her expert. (I thought I knew everything at 24 as well.)

    Eat what makes your body feel great and keeps your weight down… I’m guessing it’s mostly fruit and veg.

    That’s not to say that all is well in this new Green Religion! If you grow up with ethical vegetarians like I did, you appreciate it on some level or other! I generally love animals, vegetables etc. but guess what? I cheat. Yeah, I eat some dairy once and a while, and also some meat, fish and fowl, which I think is all quite foul, but… It tastes good. However when I feel arthritic, I quit cheating! Vegan or bust! Ya have to go vegan if you don’t want to be arthritic, and for some scatological reasons (you can actually GO). Also I think a nice and dysfunctional family full of violence helped turn me into a carnivore. My carnivore foster family where I lived for 1 year though wasn’t violent at all. Nor were they verbally abusive EVER. So obviously I wasn’t bad enough to warrant all those beatings, sarcastic and synical comments, Like coming from a hardcore old protestant family where hard work, being straight and what not is the rule, now you’ll see some people come out of the closet, be atheist or a layabout etc. I believe my “Green Religion” is good, but like all other religions, there will always be those who argue with us, and we argue for our new green religion, I just hope it doesn’t lead to wars like other religions have. We of what ever religion, belief system, need to wait for teachable moments, and quit protheletizing, nevermind what fellow veg#ns and God says!

    Personal experience:
    I was diagnosed with Rheumatoid Arthritis, I was told it is incurable and to go on Corticosteroid Immunodepressants for the rest of my life.
    I did some research and decided instead to go on a Vegan diet.
    The Reumathologist told me I’d be going back to his practice in a wheel chair ‘begging’ for medication. That was in 2009.
    This was my experience:
    1- after 3 months I was nearly pain free
    2- after 6 months I nearly regained all my joints movement.
    3- after 8 months I was more mobile that in the previous 2 years.
    4- after 8 months I bought a sailing boat and started circumnavigating the world.
    5- after 4 years I am still on a Vegan diet, still sailing, and at age 61, still more agile than all my meat eating friends.

    And, I make no money from Vegan websites…..

    When deciding the truth or lack thereof of any research, I look at the research “findings and fundings”. It seems to me that the China Study research FINDINGS are sound because of its longevity and breadth; using both animal and human subjects and multiple studies over a long span of time. Its FUNDINGS were independent, not industry-sponsored. Corporations have so much power in today’s world. When it comes to research they pay for, they have a funny way of getting the results they want. So, to anyone who’s confused, that’s how I evaluate research. Hope that helps. And if you still aren’t sure, best to try the “whole foods, plant based” lifestyle for a while and see what happens.

    In response to this article by 24 year old “writer, editor, researcher and blogger” Ms. Deinse Minger, I too am a writer, currently creating original content writing for company websites, having also developed from scratch my own original English language course which I taught myself at a language school in The Netherlands (having obtained my English teaching qualification in 2012), and a writer as someone who keeps a journal with extensive writings on various topics including exercise, health and nutrition.

    I too, like Ms. Minger have a college qualification, a BA in Economics but unlike Ms. Minger I avoid Facebook and blogging like the plague, valuing my time as I do as the most precious commodity we have on this Earth.

    Following that lengthy introduction, the point of which was not to emphasise my credentials or qualifications but rather my absolute lack of any such thing when it comes to the area of health, nutrition and biochemistry, so I feel at least equally qualified to discuss the ideas and findings of T. Colin Campbell’s ground-breaking work “The China Study”, as does the author of this article.

    However, I find it baffling how a 24 year old “blogger” with no qualifications or credentials in the aforementioned disciplines of study, has the audacity to write an article attempting to refute the claims and findings of a man with 40+ years experience in scientific research, a who was involved in the discovery of dioxin, recognized as one of the most deadly toxins ever found, a man who has written hundreds of scientific papers, a recipient of numerous awards for his work as a biochemist and a man who directed the most comprehensive study of diet, lifestyle and disease on humans, ever.

    Ms. Minger seems to think she can denounce decades of study, research and hard work carried out by a dedicated expert in the field, T. Colin Campbell, as easily as she might “like” her friends Saturday night pizza dinner posted on Facebook or Twitter. This sort of dangerous anti-social behaviour is symptomatic of the problem with generation zombie.

    Ms. Minger’s article is on the website, a website dedicated to the career of Weston A Price, a dentist who carried out research primarily on the relationship between nutrition and dental health and advocated a “nutrient dense whole foods diet”, key to which was animal fats, as the diet for optimal health.

    The Weston Price Foundation, to quote from it’s own website “supports a number of movements that contribute to this objective including accurate nutrition instruction, organic and biodynamic farming, pasture-feeding of livestock, community-supported farms, honest and informative labeling, prepared parenting and nurturing therapies.” Clearly an organization with expressed interests with farming groups and organizations and the meat industry.
    Interestingly Ms. Minger references, more than once, the work of Chris Masterjohn in backing up some of her claims against the findings in “The China Study”, the same Chris Masterjohn who at the time of writing did not have any qualifications or credentials in the areas of health, nutrition and biochemistry, much like Ms. Minger, but who does have the credentials to write a foreword in MS. WInger’s first book “Death by Food Pyramid”.

    With a tone a sarcasm and what smacks frankly of resentment and desperation by a wannabe health and nutrition expert, Ms. Winger proceeds to try to tackle the work of T. Colin Campbell in a vain attempt to discredit one of the most celebrated and decorated biochemists in the world.

    As mentioned already, being someone who values my time I do not have much more of it to waste expanding on the above content, however there are a few points in Ms. Minger’s “critique” of “The China Study” that I would like to mention;

    In his book “The China Study”, T. Colin Campbell himself, explicitly acknowledges the difficulty in proving as fact the direct cause of any disease and in this regard explains the relationship between correlation and causation and that one does not prove the other, contrary to what Ms. Minger infers.

    Ms. Minger states, in relation to plant-based proteins used in research on lab rats and referenced in the book, that “it seems those plant proteins were not only PETA approved but also the least likely to turn rat livers into tumour factories”. She states this without a shred of evidence to back up this claim.

    In one of her more ambitious contentions, Ms. Minger states “when we look at plant protein which the China Study argues so vigorously is cancer-protective – we find almost three times as many positive correlations with various cancers as we do with animal protein, including colon cancer, rectal cancer and esophageal cancer”. This claim is referenced to a study by none other that the esteemed, you guessed it, Ms. Minger herself!

    Need we say more.

    Ms. Minger, I genuinely applaud your self education and appetite for knowledge and learning and wish you well with your book and further writing. However at this stage of your career, you simply cannot write such an article attempting to rubbish the findings of a pioneering and potentially life-saving work by a recognized expert in the relevant field of study. And you certainly cannot expect to be taken seriously.

    My apologies to Ms. Minger and readers for the previous incomplete version of this post, caused by a frantic attempt to curtail my time already spent writing this lengthy and tiresome reply, something which I would usually never dream of doing, much like using Facebook or most other forms of social media. But this time given the respect and admiration I have for the content of “The China Study” I felt compelled.

    You’re a 24 year old blogger, please stick to writing about topics which you can hold an educates conversation on. You have zero education in the health field.

    People please, if you read the China Study or any similar work you would come to the same conclusion: any animal products are bad for us as humans. Why do people get so offended by this? It’s science people!
