Dash diet lowers blood pressure

Diet-DASH-fig0A new study released by Purdue University has specified that the Dash diet is linked to lowering the risk of high blood pressure. The DASH diet stands for Dietary Approaches to Stop Hypertension and limits red meat to reduce total and saturated fat as well as and is focused on increasing consumption of fruits and , whole-grains, low-fat dairy, nuts, and fish, while reducing fats, red meats, including pork, and added sugars.

The study was published by the and the DASH diet is often used to reduce blood pressure, a risk factor for cardiovascular and kidney disease. It is estimated that approximately 30 % of American adults live with hypertension and 65 percent of those 60 years and older have high blood pressure.

The research participants consisted of 19 participants with elevated high blood pressure and an average age of 61. The study’s participants consumed a DASH- for two, six-week periods, and they either ate lean pork or chicken and fish as the main protein source. They had a four-week break then consumed the alternate meat. Blood pressure was evaluated on a continual basis throughout the study, including at the beginning of each six-week period and at the end of the study.The findings revealed that consumption of these DASH-style diets for six weeks reduced all measures of blood pressure with no differences in responses between DASH with chicken and fish and DASH with pork.

‘This study supports that the DASH diet can include lean, unprocessed red meats in the appropriate serving sizes,’ said Wayne Campbell, a professor of nutrition science.

‘If people have to rely only on fish and chicken their diet choices can be limited, and our findings support that lean pork may be a viable option for people who are consuming a DASH diet without compromising the effectiveness of the diet plan,’ said Drew Sayer, a doctoral student in nutrition science and a co-author on the study.

‘The people in the study were at risk for hypertension, and they represent the 60 percent of Americans with prehypertension who are on the road to clinically high blood pressure,’ said Sayer.
