#Eating lean beef daily can help lower blood pressure, study suggestscontrary to conventional wisdom a growing body of evidence shows that eating lean beef can reduce risk factors for heart disease according to recent research by nutritional scientists. This research adds to the significant evidence including work previously done in our lab that supports lean beef's role in a heart-healthy diet said Penny M. Kris-Etherton Distinguished Professor of Nutrition Penn State. This study shows that nutrient-rich lean beef can be included as part of a heart-healthy diet that reduces blood pressure which can help lower the risk for cardiovascular disease. The DASH eating plan--Dietary Approaches to Stop Hypertension--is recommended currently by the American Heart Association to lower blood pressure and reduce risk of heart disease. People following the DASH diet are encouraged to eat fruits vegetables low-fat dairy and protein predominantly from plant sources. The Beef Checkoff Program and the National institutes of health-supported Penn State General Clinical Research center funded this research. Lean beef can be enjoyed as the predominant protein source in a DASH-like diet along with fruits vegetables and low-fat dairy to effectively help lower blood pressure in healthy individuals the researchers report in the Journal of Human Hypertension. This DASH-like diet is called also the BOLD+diet--Beef in an Optimal Lean Diet plus additional protein. Kris-Etherton and colleagues tested four diets to find the effects on vascular health. The diets tested included the Healthy American Diet --which served as the control--the BOLD+diet the BOLD diet and the DASH diet. The control diet consisted of 0. 7 ounces of lean beef per day while the DASH diet included 1. 0 ounce. The BOLD diet had 4. 0 ounces and the BOLD+diet included 5. 4 ounces of lean beef. The researchers tested the four different diets with 36 participants between the ages of 30 and 65. All participants followed each diet at different times throughout the study period. Subjects were assigned randomly an order to follow each of the four diet plans for five weeks each with a break of one week in between each new plan. Blood pressure was taken at the beginning and end of each diet period. The BOLD+diet was more effective at reducing blood pressure when compared to the other diets tested. This evidence suggests that it is the total protein intake--not the type of protein--that is instrumental in reducing blood pressure as part of a DASH-like dietary pattern the researchers stated.
