Having a cow can be a heart healthy choice

Lean beef can contribute to a heart-healthy diet in the same way lean white meats can, according to nutritional scientists.

The DASH diet -- Dietary Approaches to Stop Hypertension -- is currently recommended by the American Heart Association to lower cholesterol and reduce risk of heart disease. People following the DASH diet are encouraged to eat fish and poultry, but not much beef.

According to the Centers for Disease Control about 26 percent of American deaths are caused by heart disease.

"The DASH diet is currently the gold standard for contemporary diet recommendations," said Michael Roussell, nutrition consultant and recent Penn State Ph.D. graduate. "The DASH diet emphasizes plant protein foods, poultry, fish and small amounts of lean beef. Consumers often interpret this to mean that red meat is restricted on a healthy diet. Our research is showing that if you can keep your saturated fat levels controlled and lean beef portions in check, you can incorporate lean beef into a heart healthy diet and still see equal reductions as with white meat and fish."

Roussell worked with Penny Kris-Etherton, Distinguished Professor of Nutrition, Penn State, and colleagues to test three diets that were equally low in saturated fat to see if there were differences in cholesterol levels at the end of each testing period. They report their results in the current issue of the American Journal of Clinical Nutrition.

They tested the DASH diet, as well as the BOLD diet -- Beef in an Optimal Lean Diet -- and BOLD+ -- Beef in an Optimal Lean Diet plus additional protein. The additional protein in the BOLD+ diet included more beef, as well as other sources of protein like hummus, edamame beans and cottage cheese.

The control diet, called the healthy American diet, consisted of 12 percent saturated fat per day -- twice the saturated fat included in the three test diets -- and 0.7 ounces of beef. The DASH diet included 1.0 ounce of beef, while
