Thiamin excretion of young men adapts rapidly (t 1/2 = 1 day) to increases or decreases in thiamin intake, but is independent of the amount of carbohydrate (38–80% of energy), protein (75–200g), riboflavin (2.5–3.5 mg), water (2-fold range), and energy (in range 3200–4700 kcal/day) present in the diet. The thiamin RDA should be expressed in terms of mg/day rather than in terms of mg of thiamin per 1000 kcal of total energy or carbohydrate energy in the diet. Most stresses had little or no effect on thiamin excretion. Pyramin excretion was strongly influenced by dietary pyrimidines. |
