Philadelphia, PA, September 19, 2012 The Dietary Approaches to Stop Hypertension (DASH) diet, which promotes consumption of more fruits, vegetables, low-fat dairy products, and whole grain, and less meats and sweets, is a proven effective treatment for hypertension. For some individuals, adherence to the diet can be just as effective in lowering blood pressure as taking antihypertensive medication. A new study has found that greater adherence to the diet can lead to significant reductions in blood pressure, but that African Americans are less likely to adopt the diet compared to whites. The study is published online today in the Journal of the Academy of Nutrition and Dietetics.
"After DASH dietary counseling, African Americans increased their consumption of DASH foods, but continued to lag behind whites in overall adherence to the DASH eating plan, consuming considerably more meat, sweets, and fat, and less fruit," reports lead investigator James A. Blumenthal, PhD, Professor of Behavioral Medicine in the Department of Psychiatry and Behavioral Sciences at Duke University Medical Center in Durham, NC.
The study was a new analysis of the ENCORE study, which evaluated the effectiveness of the DASH diet alone and in combination with exercise training and weight reduction. 144 sedentary, overweight, and obese adults with high blood pressure were randomly assigned to three treatment groups. The first group ate the DASH diet and was engaged in weekly education, support, and feedback in group sessions. The second group also ate the DASH diet and received structured support and feedback, and in addition began a weight management program with caloric restriction, behavior modification, and aerobic exercise three times a week. The third group was instructed to maintain their normal diet and activity, but did not receive in instruction in the DASH diet nor were they encouraged to exercise or lose weight.
