What vitamin is associated with Pellagra?

Question

BlackTom AI · Accepted Answer

Examining the question, we need to identify which vitamin is associated with Pellagra, a nutritional deficiency condition.
Option 1: 'Niacin (B3)'. Pellagra is classically linked to a deficiency of niacin (vitamin B3) or tryptophan malnutrition, leading to the characteristic dermatitis, diarrhea, and dementia. This makes the statement scientifically accurate in the context of Pellagra.
Option 2: 'Vitamin C'. Vitamin C deficiency causes scurvy, not Pellagra. Scurvy is characterized by symptoms like gum disease, gum bleeding, and poor wound healing, which are distinct from Pellagra symptoms.
Option 3: 'Riboflavin (B2)'. Deficiency of riboflavin leads to ariboflavinosis, with signs such as cheilosis, glossitis, and angular stomatitis. This condition is unrelated to Pellagra and does not produce the classic triad.
Option 4: 'Thiamin (B1)'. Thiamin deficiency causes beriberi, which presents with neuropathy, weakness, and cardiovascular symptoms. These manifestations differ from Pellagra, indicating this option is not correct for the question.
Putting it together, the association described in the question aligns with niacin (B3) deficiency as the cause of Pellagra, while the other vitamins are linked to different deficiency diseases with distinct clinical pictures.
