The correct answer is: Pellagra is caused by a deficiency of niacin (vitamin B3), while scurvy is caused by a deficiency of vitamin C.
Niacin is a water-soluble vitamin that is essential for the proper functioning of the body. It is involved in many important bodily processes, including energy production, the synthesis of DNA and RNA, and the metabolism of carbohydrates, fats, and proteins. Niacin can be found in a variety of foods, including meat, poultry, fish, eggs, dairy products, whole grains, legumes, and nuts.
Vitamin C is also a water-soluble vitamin that is essential for the proper functioning of the body. It is involved in many important bodily processes, including the synthesis of collagen, the absorption of iron, and the maintenance of a healthy immune system. Vitamin C can be found in a variety of foods, including citrus fruits, tomatoes, broccoli, and leafy green vegetables.
Pellagra is a disease that is caused by a deficiency of niacin. It is characterized by a variety of symptoms, including diarrhea, dermatitis, dementia, and death. Scurvy is a disease that is caused by a deficiency of vitamin C. It is characterized by a variety of symptoms, including fatigue, weakness, bleeding gums, and skin lesions.
Both pellagra and scurvy are preventable diseases. They can be prevented by eating a balanced diet that includes foods that are rich in niacin and vitamin C.
