protein powder中的各种氨基酸的比例是经过调配的. 就是说某些比较少,有重要的氨基酸经过强化了. 所以营养价值比较高. 尤其对练肌肉有好处.

还有protein powder不一定是从milk中提炼的.

60g / day protein intake is a very high volume, only necessary if you are serious body builder.

I bought whey protein powder from Walmart. It's not 100% pure, for each 30g serving, only 20g protein, 5g carbs and 2.5g fat.

注意:

蛋白质不是必须的补品, 如果你的身体需要不了那么多(60g/day), 多余的会被分解, 消耗, 然后通过尿排出. 所以会加重肾的负担.

100% protein powder我没吃过, 但我想一定很不好吃. 如果你不吃肉, 想吃protein powder来补充蛋白质, 很可能一样不喜欢吃.
