A typical diet plan in DASH includes a lot of whole grains, fruits, vegetables, legumes, low-fat dairy products, fish, and poultry. The various food groups are taken based on the calorie need of the individual. The salt level is reduced gradually through weeks to allow the body to adjust to the change.
