Changes to the Women, Infants, and Children food packages implemented in 2009 improved childhood obesity outcomes, according to a study published in the American Journal of Clinical Nutrition. Researchers compared growth trajectories and other obesity outcomes with varied participation in updated packages that increased fruits, vegetables, and whole grains and reduced the amount of milk, eggs, cheese, and other high-fat and high-sugar foods. Children who participated in the new program lowered their obesity risk and had healthier growth trajectories when compared to those who received the old food packages. These results show the positive effects of dietary changes early in life and support further improvements to federal food programs.
