    This study compared the effect of Korean vegetarian and omnivorous diet on plasma carnitine concentrations and urinary carnitine excretion. Twenty lactoovovegetarian and twenty omnivorous female college students comsented to participate in this study. Daily nutritional intake and plasma and urinary nonesterified carnitine(NEC), acid-soluble acylcarnitine(ASAC), acid-insoluble acylcarnitine(AIAC), and total carnitine(TCNE) were determined. Daily protein, fat, retinol, vitamin B₂and vitamin B₁₂intakes were significantly lower for vegetarians, however, fiber, carbohydrate, β-carotene, folic acid and vitamin C consumptions were much higher for vegetarians than omnivoured. There were no differences in plasma NEC, ASAC, AIAC and TCNE concentrations between the two groups. Urinary carnitine excretion was lower in vegetarians, but only the differences in ASAC and TCNE excretions were statistically signigicant. These results suggest that the lower excretion of ASAC in vegetarians may be a reflection of their lipid metabolic state and that Korean vegetarian diets may accommodate lower carnitine intakes through dfficient urinary conservation of carnitine.
