A British medical journal suggests that sports drinks may not be the best for your kids.

Listen:

Peyton Manning Children's Hospital registered nurse Lori Walton agrees. Walton says water is probably the best form of hydration before kids hit the field or court. She adds that high-energy snacks that combine carbohydrates and protein are the best after workout snacks. Walton says they include fruit and nuts, yogurt protein bars. Walton says small, sports drinks may be okay following vigorous athletic activity to replace electrolytes.

Walton is a pediatric weight management coordinator. She works with the Lifetime Individual Fitness and Eating program. L.I.F.E for Kids aims to help children and teens manage their weight through healthy eating, physical activity and goal setting.
