Kwashiorkor in young children is caused by a diet that is
Correct answer: D. sufficient in energy but severely deficient in protein
- A. deficient in vitamin C
- B. deficient in iodine
- C. excessive in fat
- D. sufficient in energy but severely deficient in protein
Explanation
Where the diet is mostly starch, energy intake may be adequate but protein is not, so plasma protein falls, fluid is not drawn back into the capillaries and the child develops the characteristic swollen abdomen along with poor growth and a fatty liver. Marasmus, by contrast, is a shortage of both energy and protein and produces severe wasting. Vitamin C deficiency causes scurvy and iodine deficiency causes goitre.

About Human Digestive System
The human digestive system breaks food into absorbable molecules through mechanical processing, enzyme action and chemical conditions along the alimentary canal. Questions cover the mouth, stomach, small and large intestines, liver, pancreas and associated secretions, including the digestion and absorption of carbohydrates, proteins, lipids, vitamins, minerals and water.
