If you’ve been reading the news, you probably know that eating delicious foods like butter and eggs is no longer thought to increase risk of heart attack or stroke. This post discusses new information has come to light suggesting Ancel Keys suppressed evidence that polyunsaturated fats are more harmful than trans fat!
For those of you who aren’t fully convinced that butter and eggs are healthy, I’ve devoted the first half of this article to highlighting why, when your doctor recommends that you swap out saturated fats in foods like butter and eggs for polyunsaturated fat in products like Smart Balance and packaged breakfast cereals, it’s largely thanks to Ancel Keys and his misleading, even dishonest, public statements.
Back in the 1950s and 1960s, Ancel Keys designed a series of highly influential experiments that changed the course of American dietary history. Before Keys, Americans enjoyed traditional foods like butter, eggs, and bacon without worrying about their health. After Keys made the cover of Time magazine on Jan 13, 1961, the American public was introduced to the idea that saturated fats were clogging their arteries, and that idea ultimately led to a sea change in the foods we eat. Real foods would increasingly replaced by processed, and the era of obesity and chronic disease would begin.
