Eliminating meat from a terrible diet doesn't really make it any healthier, according to a study released today in the Journal of the American College of Cardiology. In fact, the study found that participants whose mostly-plant-based diets (think vegetarian or vegan) included a lot of processed foods, such as sugary beverages and French fries, were more likely to develop heart disease or die during the study period than people who avoided processed food—even if that meant eating a little meat.
