The DASH (dietary approaches to stop hypertension) Diet emphasizes foods high in nutrients such as potassium, magnesium, calcium, and fiber that have been linked to antihypertensive effects. (5) This diet is high in fruits, vegetables, low-fat dairy products, and reduced in saturated and total fat to lower blood pressure. (5) See Table 8.2. The DASH Diet is adopted by the American College of Cardiology/American Heart Association 2013 Task Force for reduction of cardiovascular risk. (6)
Low Sodium Diet
The 2300 mg Low Sodium diet is the lowest sodium restriction recommended by the Institute of Medicine to improve health outcomes in certain populations. (9) This diet is useful in preventing or controlling edema or hypertension (high blood pressure). This diet is appropriate for persons with ascites (see Chapter 9). Caution is required for use with frail elderly because weight loss may occur as a result of palatability concerns. (15, 16, 17) Elderly require higher levels of salt to detect salt flavor in their diet. (18, 19, 20) For management of fluid restrictions, see Fluid Restrictions in Chapter.
