Still, the idea stuck: Sat fat is bad fat. But now emerging research is shedding new light on the debate. A scientific review of studies involving more than 600,000 people, published in the Annals of Internal Medicine earlier this year, found no significant link between dietary saturated fat and heart disease - suggesting that we don’t, in fact, need to shun foods like red meat, butter, and whole milk for our heart’s sake. But before you go hog-wild, here’s what you should know about popular fatty foods.
There’s a difference between unprocessed meat – like beef, lamb, and pork – and the processed varieties that include sausage, bacon, and lunch meat. After analyzing 20 studies, Harvard researchers found that while eating one 3.5 – ounce serving or more of red meat daily wasn’t associated with a higher risk of heart disease, consuming just 1.8 ounces of processed meat (the equivalent of about two slices of bologna) a day was associated with a 42 percent increased risk. The main culprit might not be the saturated fat after all, but rather the high amounts of sodium (which can raise blood pressure) and preservatives (which may promote arterial hardening) in processed meat.
EAT SMART: Sticking to one to two servings of red meat per week shouldn’t have a major impact on your health if you eat well the rest of the time, says Dariush Mozaffarian, MD, an associate professor at the Harvard School of Public Health and coauthor of the Annals of Internal Medicine study. But he recommends consuming most of your protein from sources proved to be beneficial, like nuts and fish rich in unsaturated fatty acids.
