Ruminant Reality

The video of my presentation at the Ancestral Health Symposium 2012 has bee posted on YouTube.

I titled the talk "The Reality of Ruminants and Liebeg's Barrel: Examining the New 'Conventional Wisdom.'" (links are to previous posts) They say that whenever you give a talk you actually give three: There's the talk you plan to give; there's the one you give; and there's the one you think you should have given. The talk I think I should have given isn't too different from the one captured by this video.

Make Believe?

Imagine you’ve got a group of men who’ve survived a heart attack. They agree to participate in a four-year-long experiment where they’re placed onto one of two diets: Diet One is a “Mediterranean Diet” high in fruits, vegetables, legumes, fish, and poultry, along with cholesterol-rich read meat and full-fat dairy products; Diet Two is the “Prudent Diet” recommended by the American Heart Association (and, not coincidently, by most physicians), focusing on restricting saturated fat intake. What result might you expect?

Turns out that the men restricting their cholesterol and saturated fat intake had a greater than 50 percent higher rate of fatal heart attacks and 70 percent more cardiac events! And the total cholesterol, LDL, and HDL levels of both groups were almost identical.

Perhaps even more interesting is that despite the fact that this research was published in Circulation * (the American Heart Association journal, no less!) over a decade ago, we’re still being told to restrict our intake of dietary cholesterol and saturated fat!
