The document discusses a school-based intervention to reduce childhood obesity rates by limiting consumption of sugar-sweetened beverages (SSBs). It notes that 1/3 of US children are overweight, and consumption of SSBs is linked to obesity, poor nutrition, and health issues. The intervention involved a competition between grades to drink more water, nutrition education lessons, and restrictions on SSB sales in schools. The goal was to teach children healthy habits to carry into adulthood.
