I arrived in Washington, DC on Friday evening to meet with 13,000 other biological scientists for the Experimental Biology 2011 meeting and just got home Wednesday night. I was there to give a 15-minute presentation on how I fed an overdose of fructose to a couple dozen rats and it didn’t do any of the …
In a previous post, “The Great Unknown: Using the Statistics to Explore the Secret Depths of Unpublished Research,” I discussed one way a study can show something to be true when it’s false, or vice versa. If some nutrient or drug has a “true” biological effect, and we repeat many studies of the phenomenon, we …

Once upon a time, sucrose was the main ingredient in the diet of lab rats, but now starch is used. The government thought it knew what type of nutrition rats needed, so it recommended purified diets for the sake of science. Then, the rats started getting diseases, so they started tweaking the purified diets. Sound …
The first article I ever wrote about nutrition was an article for the Fall, 2004 issue of Wise Traditions called “Vitamin A: The Forgotten Bodybuilding Nutrient,” in which I argued that bodybuilders should eat nutrient-dense foods rich in vitamin A such as liver and cod liver oil in order to boost protein utilization and testosterone …
Chinese researchers provide new evidence that vitamins A and D work together in cooperative fashion, each increasing production of the other’s receptor. In pancreatic stem cells, they synergize to flip on the “neurogenin-3” switch, involved in turning stem cells into fully functional insulin-producing cells. Neither vitamin is effective alone, however. This suggests that vitamins A …
Has science proven that the minimal acceptable blood level of vitamin D, in the form of 25(OH)D, is above 50 ng/mL (125 nmol/L)? No. If you’ve been trying to maintain your levels this high because you thought this was the case, I’m sorry to break the news. There is, on the contrary, good evidence that …
This January, Dr. Linda Linday, a pediatrician who researches cod liver oil, Michael F. Holick, MD PhD, and several other researchers defended cod liver oil against criticism made a year earlier by Dr. Cannell of the Vitamin D Council and 16 other researchers. They cite the WAPF December 2008 “Cod Liver Oil Update” as an …
