对12名严格素食的男性进行了血浆牛磺酸水平和尿牛磺酸排泄量的测定，这些男性已经保持了53 . ±. 26个月（SD）和14名男性非素食对照受试者。血浆牛磺酸水平不同（45 . ±. 7比58 +-。16 μ mol/L）。尿牛磺酸排泄量较低（266 . ±. 279对903 +-。580 μ mol/d），尿N.pi.-甲基组氨酸几乎检测不到，尿N.甲基组氨酸显著减少（296 ± 0.001）。87比427 .+-. 19 μ mol/d）。对素食者的3天饮食日记的分析表明，蛋白质、碳水化合物、维生素B-6、蛋氨酸和胱氨酸的摄入量从边缘到充足;锌的摄入量不足;牛磺酸的摄入量可以忽略不计。长期缺乏饮食中牛磺酸的摄入会导致血浆牛磺酸的减少和尿牛磺酸排出量的严重限制。
Plasma taurine levels and urinary taurine excretion were measured in 12 strict vegetarian (vegan) males who had maintained a vegan diet for 53 .+-. 26 mo (SD) and in 14 male nonvegetarian control subjects. Plasma taurine levels differed (45 .+-. 7 vs 58 .+-. 16 .mu.mol/L, respectively). Urinary taurine excretion was lower (266 .+-. 279 vs 903 .+-. 580 .mu.mol/d), urinary N.pi.-methylhistidine was barely detectable, and urinary N.pi.-methylhistidine was significantly reduced (296 .+-. 87 vs 427 .+-. 19 .mu.mol/d) in the vegans. Analysis of 3-d dietary diaries kept by the vegans indicated marginal to adequate intake of protein, carbohydrate, vitamin B-6, methionine, and cystine; inadequate intake of zinc; and negligible intake of taurine. Prolonged absence of dietary taurine intake causes decreased plasma taurine and severely restricted urinary taurine output.
