Question

Deficiency of which of these vitamins has been seen in people who consumed a low-protein, corn-based diet?

1) Vitamin A
2) Vitamin B
3) Vitamin C
4) Vitamin D

Answer 1

Deficiency of Vitamin B3 is commonly associated with a low-protein, corn-based diet and can lead to pellagra, which can be prevented with a nutritious and diverse diet.

Step-by-step explanation:

Deficiency of Vitamin B3, also known as niacin, has been observed in people who consume a low-protein, corn-based diet. This condition, historically known as pellagra, is characterized by symptoms such as dermatitis, diarrhea, and dementia, and can be fatal if left untreated. Pellagra was common in areas where corn (maize), which is low in niacin and contains niacin-binding compounds, was a staple food. Ensuring a diet that includes sufficient protein and a variety of nutrients can help prevent such deficiencies.

Vitamin deficiencies can lead to a range of health issues. For example, inadequate Vitamin A can result in night blindness and increased susceptibility to infections, Vitamin C deficiency can cause scurvy, characterized by weakened connective tissues and bleeding gums, and Vitamin D deficiency can result in rickets or osteomalacia. Thus, consuming a balanced diet with enough vitamins is essential for maintaining good health.
