In some regions of the world, children suffer from a protein deficiency, known as kwashiorkor. This deficiency occurs when a child's diet is changed from
high-protein breast milk to watery cereal. Even though a child is receiving calories, the
child becomes sick and less active, and growth ceases. These symptoms are probably
due to
a. An over-consumption of complete protein foods
b. A lack of essential amino acids in the diet
Not enough carbohydrates in the diet
d. Insufficient caloric intake
