The body needs adequate amounts of thiamin, riboflavin, and niacin to function properly. What are the potential side effects and deficiency diseases associated with inadequate intake of these nutrients?

Thiamin deficiency - Beri-beri, polyneuritis, and Wernicke-Korsakoff syndrome.

Riboflavin deficiecy - cheilosis, angular stomatitis, and dermatitis.

Niacin deficiency - Pellagra (with diarrhea, dermatitis, and dementia)

Explanation:

Thiamin, riboflavin, and niacin belong to a group of vitamins known as the B-complex vitamins. The three substances are known to function as co-enzyme in different processes within the body and hence, their deificiency has several implications.

Thiamin deficiency is known to cause Beri-beri, polyneuritis, and Wernicke-Korsakoff syndrome.

Riboflavin deficiecy is known to cause cheilosis, angular stomatitis, and dermatitis.

Niacin deficiency is known to cause Pellagra with diarrhoea, dermatitis, and dementia
