A major feature of the plan is limiting intake of sodium, and it alsogenerally encourages the consumption of nuts, whole grains, fish, poultry, fruits and vegetables while lowering the consumption of red meats, sweets, and sugar. It is also "richin potassium, magnesium, and calcium, as well as protein and fiber."
The DASH diet is based on NIH studies that examined three dietary plans and their results. Noneof the plans were vegetarian, but the DASH plan incorporated more fruits and vegetables, low fat or nonfat dairy, beans, and nuts than the others studied.
