A four-year-old student gets his afternoon protein from a sandwich

Protein and vitamins are an essential part of a kid's diet: they provide the amino acid "building blocks" necessary to grow up healthy and strong. According to the USDA's Enhanced Menu Planning Approach for school lunches, students in preschool should get at least seven grams of protein and 14 milligrams of vitamin C. Students in kindergarten through grade six require at least 10 grams of protein and 15 milligrams of vitamin C. Students in grades seven through 12 require at least 16 grams of protein and 18 milligrams of vitamin C.
