The Dietary Guidelines for Americans (DGA), which are designed to promote heart health and reduce risk of chronic diseases, have been validated by a new study.
Researchers at the USDA Human Nutrition Research Center on Aging at Tufts University and Wake Forest University have devised a statistical model to assess adherence to the DGA as well as its role in reducing the risk of atherosclerosis in women.
They found that the subjects whose diet was based on whole-grain, total fat and cholesterol intake that met the guidelines experienced the greatest reduction in atherosclerotic progression.
Spokesman for the American Society for Nutrition Dr. Roger Clemens explains the findings are important as nutrition researchers continue to seek to identify foods that improve health.
"[We also work to] encourage compliance through education among the general public, health care professionals and public health policy decision-makers," he adds.
The study outcome will be used to prepare the 2010 Dietary Guidelines and has been detailed in the July issue of the American Journal of Clinical Nutrition.
