The news reported today on the continuing epidemic of childhood obesity in the United States. Quoting an MD from the east coast, the story said that 40% of a child's diet between the ages of 2 and 18 is from "empty calories".
Eating foods with empty calories adds to your waistline, but provides no nourishment. Obesity follows.
The story described the types of foods that provide empty calories. Candy, junk food, and pizza. Pizza??
How is pizza an empty calorie food? It's bread, cheese, tomato sauce, and meat or vegetable topping. Those are all healthy foods. What's the problem?
