this does not help
These are the reasons recommend that we eat certain amounts of food from the food pyramid:

Make smart choices from every food group.
Find your balance between food and physical activity.
Get the most nutrition out of your calories.
Stay within your daily calorie needs.

uh...how about to stay healthy by getting the right nutrients?
"Nutrition is an input to and foundation for health and development. Interaction of infection and malnutrition is well-documented. Better nutrition means stronger immune systems, less illness and better health. Healthy children learn better. Healthy people are stronger, are more productive"
