Protein
Protein is important for muscle growth. Lack of protein can cause growth failure, muscle loss, decreased immunity, weakening of the heart and respiratory system and death, notes the Harvard School of Public Health. The recommended daily minimum is 0.8g of protein for every kilogram of body weight per day, according to the Institute of Medicine.
Sources of protein include beef, poultry, fish, pork and other meats. Meat has lots of protein, but can also have a high fat content. Choose fish or lean meats and smaller portions to keep the amount of saturated fat in your diet low. Saturated fats are not good fats. Eggs are an excellent source of protein. A good mix of proteins includes low fat dairy, soy products and protein containing vegetables.
