After decades of failure, maybe government should get out of the business of giving dietary advice.
With the release of the eighth edition of the U.S. government’s Dietary Guidelines expected by year’s end, it seems reasonable to consider—with the “obesity plague” upon us and Americans arguably less healthy than ever before—whether the guidelines are to be trusted and even whether they have done more harm than good.
Many Americans have lost trust in the science behind the guidelines since they seem to change dramatically every five years. In February, for example, the Dietary Guidelines Advisory Committee declared that certain fats and eggs are no longer the enemy and that cholesterol is “not considered a nutrient of concern for overconsumption.” This, after decades of advising Americans to “watch their cholesterol.”
Such controversy is nothing new. U.S. Dietary Guidelines were first released by the Agriculture Department and the Department of Health and Human Services in 1980. One nutrition expert at the time, Edward “Pete” Ahrens, a groundbreaking researcher on fat and cholesterol metabolism, called the guidelines “a nutritional experiment with the American public as subjects . . . treating them like a homogeneous group of Sprague-Dawley rats.”
