Improperly Prepared Grain Fiber can be HarmfulLast year, I published a post on the Diet and Reinfarction trial (DART), a controlled trial that increased grain fiber intake using whole wheat bread and wheat bran supplements, and reported long-term health outcomes in people who had previously suffered a heart attack (1). The initial paper found a trend toward increased heart attacks and deaths in the grain fiber-supplemented group at two years, which was not statistically significant.What I didn't know at the time is that a follow-up study has been...

Dinner with Taubes, Eades and Hujoel
Gary Taubes gave a lecture at UW last Thursday. Thanks to all the Whole Health Source readers who showed up. Gary's talk was titled "Why We Get Fat: Adiposity 101 and the Alternative Hypothesis of Obesity". He was hosted by Dr. Philippe Hujoel, the UW epidemiologist and dentist who authored the paper "Dietary Carbohydrates and Dental-Systemic Diseases" (1).Gary's first target was the commonly held idea that obesity is simply caused by eating too much and exercising too little, and thus the cure is to eat less and exercise more. He used numerous...

Copper in Food
Sources of CopperIt isn't hard to get enough copper-- unless you live in an industrial nation. I've compiled a chart showing the copper content of various refined and unrefined foods to illustrate the point. The left side shows industrial staple foods, while the right side shows whole foods. I've incorporated a few that would have been typical of Polynesian and Melanesian cultures apparently free of cardiovascular disease. The serving sizes are...

Interview with John Barban
I recently did a podcast interview with John Barban from the Adonis Lifestyle blog. We talked mostly about fat mass and the body fat "setpoint". As it turns out, what I said must have been at odds with John's philosophy, because he posted another podcast the next week that appears to be about why he disagrees with me!Anyway, enjoy the interview.I did another one recently with Jimmy Moore that's coming so...

Full-fat Dairy for Cardiovascular Health
I just saw a paper in the AJCN titled "Dairy consumption and patterns of mortality ofAustralian adults". It's a prospective study with a 15-year follow-up period. Here's a quote from the abstract:There was no consistent and significant association between total dairy intake and total or cause-specific mortality. However, compared with those with the lowest intake of full-fat dairy, participants with the highest intake (median intake 339 g/day) had reduced death due to CVD (HR: 0.31; 95% confidence interval (CI): 0.12–0.79; P for trend = 0.04)...

Copper and Cardiovascular Disease
In 1942, Dr. H. W. Bennetts dissected 21 cattle known to have died of "falling disease". This was the name given to the sudden, inexplicable death that struck herds of cattle in certain regions of Australia. Dr. Bennett believed the disease was linked to copper deficiency. He found that 19 of the 21 cattle had abnormal hearts, showing atrophy and abnormal connective tissue infiltration (fibrosis) of the heart muscle (1).In 1963, Dr. W. F. Coulson and colleagues found that 22 of 33 experimental copper-deficient pigs died of cardiovascular...

Magnesium and Vitamin D Metabolism
Ted Hutchinson posted a link in the comments section of my last post, pointing to a page on the Vitamin D Council's website where Dr. John Cannell discusses cofactors required for proper vitamin D metabolism. It's actually the site's home page, highlighting how important he feels this matter is. In this case, 'cofactor' simply means another nutrient that's required for the efficient production and use of vitamin D. They include:MagnesiumZincVitamin K2Vitamin ABoronAnd probably others we aren't yet aware of. On another page, Dr. Cannell links...

Low Vitamin D: Cause or Result of Disease?
Don Matesz at Primal Wisdom put up a post a few days ago that I think is worth reading. It follows an e-mail discussion between us concerning a paper on magnesium restriction in rats (executive summary: moderate Mg restriction reduces the hormone form of vitamin D by half and promotes osteoporosis). In his post, Don cites several papers showing that vitamin D metabolism is influenced by more than just vitamin D intake from the diet and synthesis in the skin. Celiac disease patients have low 25(OH)D3, the circulating storage form of vitamin D,...
