Pellagra constitutes a disorder provoked by an inadequacy of vitamin __________________________?
Show answer Hide answer
Answer: B. Niacin
Explanation
Pellagra develops directly when the human body lacks sufficient niacin or vitamin B3. Inadequate dietary intake prevents the metabolic synthesis required for normal cellular function and health. Clinical diagnosis confirms niacin deficiency as the primary biochemical trigger of this specific disease. Niacin, also known as vitamin B3, plays a critical role in cellular energy metabolism. Dietary sources rich in niacin include meat, fish, whole grains, and fortified food products. The deficiency historically manifests through the classic symptoms known widely as the four Ds.
Populations consuming unfortified corn as a primary staple diet frequently face severe pellagra risks. Public health nutrition programs combat this deficiency by fortifying common flours with essential vitamins. Understanding vitamin deficiencies helps medical professionals design effective dietary interventions for vulnerable communities. Riboflavin deficiency typically results in distinct clinical conditions such as ariboflavinosis and mouth sores. Pyrodoxin deficiency manifests as neurological symptoms and anemia rather than the classic pellagra syndrome. The correct option is clearly listed among the choices, making the none alternative incorrect.
