Initial BOLD Results
During the 2007 fiscal year, the beef checkoff initiated a major human clinical research trial aimed at comparing the common gold standard diet recommended in Dietary Guidelines, known as the DASH diet, to a higher-beef version of the DASH diet. On average, the standard DASH diet contains only two beef meals per week. Internationally recognized nutrition researcher, Penny Kris-Etherton, PhD, RD and her team of scientists at Pennsylvania State University named this checkoff study "BOLD" – an acronym for "Beef in an Optimal Lean Diet" because the BOLD diet actually provided an average of 12 lean beef meals per week.
Subjects consumed beef meals prepared using recipes from the checkoff funded Healthy Beef Cookbook. Phase I of the BOLD study evaluated the effects of the BOLD diet on total cholesterol, LDL cholesterol, triglycerides and other emerging cardiovascular disease risk factors in individuals with moderately high cholesterol. Initial results are now available and show the BOLD diet is as effective as the DASH diet for improving blood lipids. This data supports the frequent inclusion of lean beef in a heart-healthy diet. The results have recently been presented at two of the leading national scientific conferences. Scientific papers are being prepared for submission to peer-reviewed scientific journals. A second phase of the study evaluating the BOLD diet in subjects with Metabolic Syndrome will be completed this summer. The timing of the results are important considering the expected release of the 2010 Dietary Guidelines late summer or early fall of 2010.
