Based on a close look at the everyday eating habits of a large group of men and women, researchers have found that people whose diets were most similar to the 2005 Dietary Guidelines for Americans were least likely to have metabolic syndrome. For the study, metabolic syndrome was defined as a condition occurring among people who have at least three of the following health risks: abdominal obesity, poor blood sugar control, high blood fats, low levels of HDL “good” cholesterol, and high blood pressure.
