Effect of DASH on HF Outcomes Heart Failure Status in Older Adults (DASH HF)

The DASH diet is a heart-healthy eating pattern that is focused on adequate consumption of fruits, vegetables, whole grains, low-fat dairy, fish, poultry, beans, nuts, and vegetables oils while emphasizing limited intake of foods containing saturated fat, such as fatty red meats, full-fat dairy products, and tropical oils, such as coconut, palm kernel, and palm oils, as well as sugar-sweetened beverages and sweets. The chosen 4 week intervention duration phase is consistent with previous research showing positive effects of consuming a sodium-reduced dietary intervention on volume status and is longer than in other studies showing positive effects of DASH diet consumption on cardiac outcomes among HF patients. Potential carryover effects are minimized by a washout period of 4 weeks. The meal plan has been previously developed based on NHLBI guidelines for the DASH diet.
