NIH: For the seventh year in a row, U.S. News and World Report ranked the NIH-developed DASH Diet “best overall” diet. With
 its focus on vegetables, fruits, whole grains, low-fat dairy, and lean 
proteins, the diet also ranked as the best for diabetes and healthy 
eating, and tied as the best for heart disease prevention.
Researchers funded by NIH’s National Heart, Lung, and Blood Institute
 (NHLBI) developed DASH, which stands for Dietary Approaches to Stop 
Hypertension, to prevent and treat high blood pressure, but the diet 
also has been highly effective in lowering blood cholesterol.
DASH is not a fad diet, but a healthy eating plan that supports long-term lifestyle changes. It is low in saturated fat, trans
 fat, and cholesterol. It emphasizes fruits, vegetables, and low-fat 
dairy foods, and includes whole grains, poultry, fish, lean meats, 
beans, and nuts. It is rich in potassium, calcium, and magnesium, as 
well as protein and fiber. However, it calls for a reduction in high fat
 red meat, sweets, and sugar-containing beverages.
The DASH diet was one of 38 diets reviewed and scored by the U.S. News and World Report’s
 panel of health experts. To receive top ratings a diet has to be 
relatively easy to follow, nutritious, safe, effective for weight loss 
and protective against diabetes and heart disease.
