沒那麽簡單

舉個例子

Optimum Nutrition's Gold Standard 100% Whey protein powder typically contains a protein blend of whey protein isolate, whey protein concentrate, and whey peptides. It also includes ingredients like natural and artificial flavors, lecithin (often soy or sunflower), and sometimes thickeners like xanthan gum. Sweeteners like sucralose and acesulfame potassium are also common. 

後麵這些提升口感和味道的東西才是問題所在。

所以我到不得已的時候才用蛋白粉。能吃真正食物的時候就不去喝蛋白粉。
