We learned this as children--there are four main food groups:

Dairy--for calcium and protein
Protein--for tissue growth and replacement
Fruits and Vegetables--for vitamins and minerals and general health
Grains/Breads--for carbohydrates and energy.

The "four food groups" concept was promoted by the dairy industry to make dairy products seem essential to a healthy diet. Actually, adult mammals do not need milk. In Japan and China milk/dairy products are not part of their traditional diet, and they live longer than Westerners, overall. There is some evidence that excessive dairy products are associated with Allergies and osteoarthritis. Dairy products are not necessary for adults or children past the weaning age. However, moderate amounts of dairy products are a good source of protein and calcium.
