               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.
