摘要

我们检测了年轻男性在摄入两种等氮剂量(2 × 20 g蛋白质)的希腊酸奶(GY)和脱脂牛奶(milk)后4小时血中支链氨基酸(BCAA)、胰岛素和葡萄糖的反应。GY组与MILK组相比，亮氨酸和支链氨基酸的峰值浓度和曲线下面积更大，达到最大亮氨酸/支链氨基酸浓度的时间相似。我们证明了不同的蛋白质匹配的天然乳制品引起不同的餐后氨基酸反应。

Differential plasma branched-chain amino acid responses following the consumption of Greek-style yogurt and skimmed milk.

We examined postprandial branched-chain amino acid (BCAA), insulin, and glucose responses in blood for 4 h following the consumption of two isonitrogenous doses (2 × 20 g protein) of Greek-style yogurt (GY) and skimmed milk (MILK) in young males. Peak leucine and BCAA concentrations and areas under the curve were greater after GY versus MILK, and time to maximal leucine/BCAA concentrations was similar between conditions. We demonstrated that different protein-matched wholefood dairy products elicit different postprandial aminoacidemic responses.
