The Childhood Diabetes Reduction Act of 2026 targets childhood diabetes through labeling requirements for food and beverages, restricting unhealthy food advertising to children, and funding public education on nutrition and physical activity. It includes appropriations for nutrition science research and aims to raise awareness about the health effects of ultra-processed foods. The bill defines and prohibits child-directed advertising for junk food, requires health warnings on such ads, gives the FTC authority to enforce measures and revoke restrictions on regulating children's advertising. These efforts seek to reduce children's exposure to unhealthy food marketing and promote healthier lifestyle choices.
