snacks like ice cream, chocolate, soft

games like Play Station, be in front of the computer, or watch TV. In the past,
children ate less bad food and exercised more than children today.

eat better food and avoid snacks. Schools must also be responsible. The

food. Schools and parents should push kids to play sports and exercise
more. Children need to be healthy.
