Final answer:
A diet deficient in protein can lead to a condition called kwashiorkor, which causes edema and a distended belly.
Step-by-step explanation:
True. A diet that has enough energy but is deficient in protein can lead to a condition known as kwashiorkor, which is a type of undernutrition syndrome. Kwashiorkor is characterized by edema, or fluid accumulation, in various parts of the body, including the abdomen. The distended belly seen in kwashiorkor is primarily due to the accumulation of fluid in the abdominal cavity, rather than the stomach expanding in response to lack of food.
