Stunted _______________________ in children 15. People who choose not to eat meat are called _____________________. They have to be careful to get enough complete protein in their diets through other ways. *Although most vegetarians enjoy healthy benefits from eating a diet that is generally high in fiber and low in saturated fats and cholesterol, vegetarianism doesn’t guarantee proper nutrition. Remember, your body requires complete proteins from animal sources daily. It cannot survive on incomplete proteins alone. 2 EGGS The incredible, edible egg! 1. Label the parts of the egg: A.
