Presidentβs Message
Yes, Virginia, there really is vitamin D in lard! This is what we found as a result of testing seven foods using fluorescence detection (see page 33). We also found vitamin D in cod liver oil, chicken liver, goose fat, egg yolk and two samples of butter, but the real surprise was the indication of high levels of vitamin D in lard!
Years ago, lipid researcher Mary Enig told me about studies carried out by USDA which found substantial amounts of vitamin D in lard. These findings were never published, and even today, food tables do not show lard as a significant source of vitamin D. An AI search tells us that βon average, lard provides about 1-2 IU of vitamin D per tablespoon. It is not a significant source of vitamin D compared to fortified foods or fatty fish.β
Some years ago we had some lard tested by an independent laboratory; which found very high levels of vitamin D in lard from pasture-fed pigs, as much as 1000 IU per tablespoon. The technician explained to me that it is difficult to separate vitamin D in lard from its matrix, but he knew how to do it; hence, the high levels that he found, levels similar to those found in the early USDA tests. But when we sent lard in for a second test, he found almost none. When I questioned him on this, he became very evasive, almost as though heΚΌd been warned not to do the testing protocol that separated the vitamin D from its matrix and yielded high results.
The testing we have just done does not give us actual values for vitamin D in lard. However, it is clear that lard is a very good source of vitamin D, with a much higher intensity than any of the other foods we tested.
More testing is planned. Stay tuned for results for vitamins A and K2!
By the way, the fluorescence testing shows us that, indeed, vitamins do exist! The current scuttlebutt making the rounds on the Internet holds that there is βno such thing as vitaminsβ because to find them you need to subject the food sample to high heat, acids and other intense chemical processes. But fluorescence testing merely shines a light on the food. Our study found the same vitamin-D wavelength in supplements and in real food. Of course, in the real food, vitamin D is supported by co-factors such as vitamins A and K2, while in the isolated vitamin D, the lack of co-factors means that the vitamin can have toxic effects.
WeΚΌre looking forward to the results of further research but meanwhile you can enjoy lard as a powerhouse of vitamin D, a real health food!
