Back at our 2nd Annual sale, we invited Dr. Stephen Smith to present on the many health benefits of Wagyu beef. Ever since then, we have been keeping our proverbial ear to the ground when scientific studies come up about beef and cholesterol.
A recent Food Systems Insider article got our attention.
According to a recent study undertaken by our friend Dr. Stephen Smith, the public perception that beef from grass-fed cattle is healthier is flawed. Smith’s study aimed to compare how product from grass-fed and grain-fed cattle effected LDL and HDL cholesterol levels.
“There really were no negative effects of feeding ground beef from the pasture-fed cattle,” Smith said. “We did see many positive effects in men that consumed ground beef from corn-fed cattle. The ground beef from the USDA Prime [corn-fed] cattle increased HDL cholesterol and LDL particle diameter. Both [of these] effects are protective against cardiovascular disease. The Prime [corn-fed] ground beef also decreased insulin, so it may have some protective effect against type II diabetes.”
Smith said the study results surprised many. “As we talked to some user groups and told them that we had found pasture-fed beef is higher in saturated trans-fat, they were shocked.”
