New study says beef can lower bad cholesterol
A new study has suggested that beef can play a role in a cholesterol-lowering diet, despite commonly held beliefs.
The study found that diets including lean beef every day are as effective in lowering total and LDL "bad" cholesterol as the "gold standard" of heart-healthy diets (DASH, Dietary Approaches to Stop Hypertension).
The Beef in an Optimal Lean Diet (BOLD) clinical study, conducted by The Pennsylvania State University (PSU) researchers, evaluated adults with moderately elevated cholesterol levels, measuring the impact of diets including varying amounts of lean beef on total and LDL cholesterol levels.
Study participants experienced a 10 percent decrease in LDL cholesterol from the start of the study, while consuming diets containing 4.0 and 5.4 oz. of lean beef daily.
"This research sheds new light on evidence supporting lean beef's role in a heart-healthy diet. Study participants ate lean beef every day and still met targets for saturated fat intake," said Penny Kris-Etherton, PhD, RD, distinguished professor of nutrition at PSU and the study's principal investigator.
"This study shows that nutrient-rich lean beef can be included as part of a heart-healthy diet that improves risk factors for cardiovascular disease," Kris-Etherton added.
The study has been published in the American Journal of Clinical Nutrition.
