Antiberi-beri factor, also known as thiamine, is an essential nutrient needed by the body to maintain proper functioning of the nervous system and metabolism. Thiamine is found in a variety of foods such as grains, meat, and vegetables. Other synonyms for antiberi-beri factor include vitamin B1, thiamin, and aneurin. Thiamine is important for the conversion of carbohydrates into energy, as well as for the production of DNA and RNA. A deficiency in thiamine can lead to beriberi, a disease characterized by weakness, numbness, and an enlarged heart. Ensuring adequate intake of thiamine is crucial to maintain overall health and well-being.
