The CDC recommends a daily protein allowance of 52 grams for boys between the ages of 14 and 18, and 46 grams for girls of the same age. Children between 9 and 13 should consume about 34 grams, and children between 4 and 8 should consume 19 grams. Toddlers and infants between ages 1 and 3 should have 13 grams per day.

A well-rounded diet should include major sources of protein, such as beef, fish, dairy products, poultry, nuts and legumes, KidsHealth states. Consuming dietary protein on a daily basis aids the body in growing new cell tissue and repairing damage. Protein molecules in body tissue are made up of chains of amino acids, or chemical compounds that determine how different types of cells function.

While the body produces 13 amino acids naturally, dietary protein contributes the nine essential amino acids, helping the body to make a variety of chain combinations, explains KidsHealth. With the right amino acids, proteins can perform vital functions, such as building tissue in the heart muscle and producing hemoglobin to transmit oxygen throughout the body.
