Eating lean beef daily can help lower blood pressure

18.07.2014

Contrary 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 currently recommended 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.

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 also called 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 randomly assigned 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.

Im Focus: Viaducts with wind turbines, the new renewable energy source

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

The Juncal Viaduct, in Gran Canaria, has served as a reference for Spanish and British researchers to verify that the wind blowing between the pillars on this...
