Thiamin

Thiamin is one of the B vitamins. It plays an important role in metabolizing carbohydrates and fat to produce energy for the body. Thiamin is essential for normal growth and development. It helps to maintain proper functioning of the heart, nervous, and digestive systems.

Deficiencies: Syndromes related to thiamin deficiency include beriberi and Wernicke-Korsakoff, which are also associated with chronic alcoholism. Alcoholism, in fact, can lead to thiamin deficiency. Thiamin deficiency may also result in neruodegeneration, wasting, and even death.

Food sources: Thiamin is present in many dietary products, but is found in large amounts in lean pork, legumes and yeast. Whole grain products, breads and cereals are the major dietary contributors.
