By now, many have heard of the latest "study." Oh, sure. It's already in the news. We randomly assigned 811 overweight adults to one of four diets; the targeted percentages of energy derived from fat, protein, and carbohydrates in the four diets were 20, 15, and 65%; 20, 25, and 55%; 40, 15, and 45%; and 40, 25, and 35%. The diets consisted of similar foods and met guidelines for cardiovascular health. [emphasis added] That emphasis hides a lot of sin, I'll bet. Well, no need to guess, as they provide a reference for such guidelines: ...consume a diet rich in vegetables and fruits; choose whole-grain, high-fiber foods; consume fish, especially oily fish, at least twice a week; limit intake of saturated fat to <7% of energy, trans fat to <1% of energy, and cholesterol to <300 mg/day by choosing lean meats and vegetable alternatives, fat-free (skim) or low-fat (1% fat) dairy products... No wonder "high fat" is only 40%, and I'll bet they had a tough time getting even to that level. If I recall correctly, the average American diet is already about 30% from fat, so what are they showing? They certainly aren't emulating the Tokelauans at 50%...
