In addition to its effect on ideal protein diet plan phase 1 pdf pressure, it is designed to be a well-balanced approach to eating for the general public. The DASH diet is based on NIH studies that examined three dietary plans and their results.
DASH plan incorporated more fruits and vegetables, low fat or nonfat dairy, beans, and nuts than the others studied. Those with hypertension dropped by 11 and 6 mm Hg, respectively. These changes in blood pressure occurred with no changes in body weight. The DASH and DASH-sodium trials demonstrated that a carbohydrate-rich diet that emphasizes fruits, vegetables, and low-fat dairy products and that is reduced in saturated fat, total fat, and cholesterol substantially lowered blood pressure and low-density lipoprotein cholesterol. 50 million people in the U. The higher the BP, the greater is the chance of heart attack, heart failure, stroke, and kidney disease.
The prevalence of hypertension led the U. In 1992 the NHLBI worked with five of the most well-respected medical research centers in different cities across the U. Two DASH trials were designed and carried out as multi-center, randomized, outpatient feeding studies with the purpose of testing the effects of dietary patterns on blood pressure. The standardized multi-center protocol is an approach used in many large-scale multi-center studies funded by the NHLBI.
A unique feature of the DASH diet was that the foods and menu were chosen based on conventionally consumed food items so it could be more easily adopted by the general public if results were positive. The initial DASH study was begun in August 1993 and ended in July 1997. Contemporary epidemiological research had concluded that dietary patterns with high intakes of certain minerals and fiber were associated with low blood pressures. The nutritional conceptualization of the DASH meal plans was based in part on this research. Two experimental diets were selected for the DASH study and compared with each other, and with a third: the control diet. Magnesium and Potassium levels were close to the 75th percentile of U. The DASH diet was designed to provide liberal amounts of key nutrients thought to play a part in lowering blood pressure, based on past epidemiologic studies.
