The evidence is growing stronger that eating red meat (beef, pork, lamb) and processed red meat (bacon, hot dogs, deli meats) increases the risk of diabetes, even among people who consume only small amounts. The latest support comes from a “meta analysis,” or statistical summary, that combined findings from the long-running Nurses’ Health Study I and II and the Health Professionals Follow-Up Study with those of six other long-term studies. The researchers looked at data from roughly 440,000 people, about 28,000 of whom developed diabetes during the course of the study. (43) They found that eating just one daily 3-ounce serving of red meat—say, a steak that’s about the size of a deck of cards—increased the risk of type 2 diabetes by 20 percent. Eating even smaller amounts of processed red meat each day—just two slices of bacon, one hot dog, or the like—increased diabetes risk by 51 percent.
Foods might sometimes appear to be packaged into individual serving sizes even though they contain two or more servings per package. To determine that, look at "serving size" and "servings per container" at the top of any food label. For example, if a serving size is 1 and there are 2 servings per container, you will need to double all of the nutrient values on the label in order to get a clear picture of the value of the entire container.
