• 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.
