3. Naukowe uzasadnienia wpływu na zdrowie człowieka

Thiamine (as thiamine diphosphate, a co-enzyme for several oxidative decarboxylation reactions and for transketolase) has a central role in energy-yielding metabolism, especially in the metabolism of carbohydrates and of branched-chain amino acids (Bender, 1999; EC, 2003). Thiamine (as thiamine triphosphate), has a function in nerve conduction (Bender, 1999; IoM, 1998). Thiamine deficiency can result in three distinct syndromes: Beriberi, a chronic peripheral neuritis, which may or may not be associated with heart failure and oedema, acute pernicious (fulminating) beriberi, in which heart failure and life-threatening metabolic acidosis predominate, with little or no evidence of peripheral neuritis, and central nervous system disturbances, Wernicke's encephalopathy with Korsakoff's psychosis (SCF, 1993).
