"Over the past several decades, numerous studies have found that indigenous populations have low serum cholesterol and triglyceride levels," Cordain says. This comes in spite of the fact that many modern nutritionists would likely not approve their diets. "Previous studies by myself and colleagues had found that nearly all - 97 percent - of the worlds hunter-gatherer societies would have exceeded recommended guidelines for fat," Cordain says. Watkins says that even though this may be surprising to many people, it fits exactly with what research is showing about the importance of specific types of fat in the diet. "Current research is showing that, with the decline of fat in the diet, the amount of fat isnt as important as the relative amounts, or ratio, of specific fats in your diet. Its a qualitative issue, not a quantitative issue," he says.
