               Thiamin (vitamin B1) is a water-soluble vitamin that

          was the first identified member of the TB complex group.

               Functions: Helps convert carbohydrates to energy; aids

          in nerve cell functioning.

               Sources: Brewer's yeast; lean cuts of pork;

          whole-grain or enriched cereal grain products; legumes;

          liver, heart and kidneys; nuts and seeds.

               Deficiency: Thiamin deficiency causes beriberi, a

          disease whose symptoms include anorexia, weakness, lack of

          coordination, muscle wasting, paralysis of the eye muscles,

          mental confusion, rapid heartbeat, edema, and enlarged

          heart. Deficiency is sometimes seen in this country in

          people with alcoholism and certain medical conditions.

              Excess: High intakes appear nontoxic since excess

          thiamin is easily excreted by the kidneys.
