Food Taxes Could Improve America's Health
Taxing unhealthful foods may be an effective way to control weight and prevent common chronic diseases, according to a new study. As part of the Coronary Artery Risk Development in Young Adults (CARDIA) Study, researchers looked at 20 years of food intake, food costs, and health outcomes for 5,115 participants. They found that as the price of foods—specifically soda and pizza—increased, intake decreased, leading to fewer calories consumed, lower body weights, and improved insulin function.
