deficiency. Kwashiorkor is most often encountered in developing countries in which the diet is high in starch and low in proteins. It is common in young children weaned to a diet consisting chiefly of cereal grains,
cassava https://www.britannica.com/plant/cassava | |
, plantain, and sweet potato or similar starchy foods. The condition in children was first described in 1932. The term
kwashiorkor means “deposed child” (“deposed” from the mother’s breast by a newborn sibling) in one African
dialect https://www.merriam-webster.com/dictionary/dialect | |
and “red boy” in another dialect. The latter term comes from the reddish orange discoloration of the hair that is characteristic of the

. Other symptoms include dry skin and skin rash, potbelly and
edema https://www.britannica.com/science/edema | |
, weakness, nervous irritability,

Explanation:
Kwashiorkor is the disease that occurs in one-to-four-year-old children from a protein-deficient diet. Here is a detailed explanation of the answer:
1. Kwashiorkor:
- Kwashiorkor is a form of severe protein-energy malnutrition that occurs due to a deficiency of protein in the diet.
- It commonly affects children aged one to four years who consume a diet low in protein but relatively high in carbohydrates.
- The main cause of Kwashiorkor is an inadequate intake of protein, which is essential for the growth and maintenance of body tissues.
- Symptoms of Kwashiorkor include edema (swelling) in the legs, feet, and abdomen, poor growth, muscle wasting, skin changes, hair changes, and weakened immune system.
2. Other Diseases:
- The other diseases listed in the options, namely Whooping Cough, Diphtheria, and Tetanus, are not directly caused by protein deficiency.
- Whooping Cough (pertussis) is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis.
- Diphtheria is an infectious disease caused by the bacterium Corynebacterium diphtheriae, which primarily affects the throat and nose.
- Tetanus is a serious bacterial infection caused by the bacterium Clostridium tetani, which enters the body through open wounds.
Conclusion:
Among the given options, Kwashiorkor is the only disease that occurs in one-to-four-year-old children from a protein-deficient diet. The other listed diseases, namely Whooping Cough, Diphtheria, and Tetanus, are caused by different bacteria and are not directly related to protein deficiency.
