Why We Need Carbs

One of the lessons that comes across most clearly from the studies that Weston Price documented in Nutrition and Physical Degeneration is that, although traditional diets all emphasized nutrient-dense foods, the specific mix of animal and plant foods was widely variable. Since it is primarily plant foods that provide carbohydrate, the carbohydrate content of traditionalContinue Reading

How to Know if Your Genetics Contribute to Blue Light Sensitivity and Poor Sleep — and What to Do About It

In a previous post, I discussed the role that vitamin A plays in generating our circadian rhythm and ensuring good sleep and alertness during the day by interacting with a protein in our retina known as melanopsin. There is a very small but growing body of literature suggesting that variations in the gene for melanopsinContinue Reading

Saturated Fat Does a Body Good

Exploring the Biological Roles of These Long-Demonized Yet Heroic Nutrients Since the rise of the diet-heart hypothesis in the 1960s, the idea that saturated fat is the “bad fat” has dominated the fields of nutrition science and medicine. This, combined with the observation that we can make our own saturated fat from carbohydrate, has ledContinue Reading

As the Cholesterol Consensus Crumbles, the Stance Against Saturated Fat Softens

In the last year, we have seen the consensus against cholesterol shatter and crumble before our eyes. The consensus against saturated fat has remained strong, but in the last week we have seen it begin to soften. Here’s my take.Continue Reading

Vitamin A Plays an Essential Role in Setting the Circadian Rhythm and Allowing Good Sleep

Although I have long been aware of vitamin A’s essential role in creating vision, I only recently discovered that vitamin A plays an analogous role in setting our circadian rhythm. When blue light from sunshine enters our eyes, vitamin A translates it into a signal that tells our brain it is daytime. When this signalContinue Reading

Vitamin D in Cod Liver Oil

An Enduring Mystery ARTICLE SUMMARY • In recent years, controversy has erupted over whether vitamin D2 or vitamin D3 is the predominant form of vitamin D in cod liver oil. • Research in the 1930s suggested that there were at least four if not six forms of vitamin D in cod liver oil. • Recent researchContinue Reading

When SAMe Helps, Consider Magnesium and Your Metabolic Rate

I have written quite a bit recently about the methylation cycle and its relation to nutrient balance. At Wise Traditions this November in Anaheim, one of my three talks will expand these ideas to include targeting methylation nutrition to individual needs based on genetics and health status. Here, I’d like to chip away at oneContinue Reading

Are Kombucha and Other Fermented Foods Toxic Because of Their Aldehyde Content?

In my last post, I addressed the first of two questions raised by a reader in response to a newsletter circulated by a representative of Biotics Research Canada, citing articles from Dr. Lawrence Wilson and Dr. Mark Hyman. In that post, I addressed the question of whether we should avoid animal protein in order toContinue Reading

Should We Avoid Animal Protein to Optimize Methylation?

A reader asked me to respond to a newsletter recently distributed through email by a representative of a company called Biotics Research Canada that cited two older articles by Dr. Lawrence Wilson and Dr. Mark Hyman arguing that animal protein should be restricted to optimize a biochemical process that is incredibly important to our healthContinue Reading

Did Cod Liver Oil Contribute to the Historical Decline in Measles Mortality and Mortality From Other Infectious Diseases?

Measles has been in the news a lot lately. It therefore seems timely to fulfill my now more than two-year-old promise to write a blog on the possibility and evidence that cod liver oil may have contributed to the historical decline in mortality from measles and other infectious diseases.Continue Reading
