Don't feel you have to avoid red meat. It's an important source for iron and zinc. Choose cuts of meat that are low in fat. If you don't eat red meat yourself, consider offering it to your children because of the iron and zinc in it. After a child is weaned from breast milk or formula, give him whole milk until he is 2 years old.
Whole milk is all right for older children, too.
Fat Children need fat with their meals to make the food taste good. If food is too plain, they won't eat it. Children also need fat with a meal so they don't get hungry right away. At times, children have growth spurts and need extra fat so they can get enough calories. In general, be moderate in the amount of fat you use in preparing a meal.
