But there are two problems in that thinking. The first problem is that almost half of the fat in beef is a monounsaturated fat called oleic acid—the same heart-healthy fat that’s found in olive oil. Second, most of the saturated fat in beef actually decreases your heart-disease risk—either by lowering LDL (bad) cholesterol, or by reducing your ratio of total cholesterol to HDL (good) cholesterol.
And besides being one of the most available sources of high-quality protein, beef also provides many important nutrients such as iron, zinc, and B vitamins. So the idea that beef is bad for you couldn’t be further from the truth.
