「許多人不知道有關BCAA(支鍊胺基酸)的真實資料,
因此浪費了大把的辛苦錢在BCAA補品上,
這對於習慣服用BCAA的人來說可能是一件刺耳的消息,
但我希望這能幫助你對於吃進嘴裡的食物再多加思考,
並且將不必要(甚至可能有害)的東西從採購清單中劃掉。」
以下是幾點為何Alan Aragon認為服用BCAA是浪費錢的行為,
每一點都有引用文獻,但礙於篇幅我就精簡不直翻了:
1. 日常飲食中的蛋白質就包含了18~26%的BCAA。
2. 與等價的BCAA相比,乳清有著更強的合成/抗分解效力。
3. 因為高品質的蛋白質擁有BCAA所沒有的許多必需胺基酸,更能幫助合成效應。
4. 幾乎沒有研究證據表明BCAA對於肌肉蛋白質合成或是增加肌肉重有額外幫助。
5. 有些研究宣稱BCAA可以減少痠痛,但比較對象總是沒有攝取等量的蛋白質。
6. 有些人認為空腹做心肺運動,若沒有攝取胺基酸補品,肌肉就會分解,
但研究做起來不是這樣。當蛋白質攝取量一樣時,沒有攝取胺基酸補品並不影響身體組成。
7. 大概只有某些必須進行低蛋白飲食的人,
(例如:某些肝腎疾病) 會真的需要BCAA。
「儘管如此,如果你不介意花錢購買功能相同但卻異常昂貴的調味水,
那就隨你便吧!」
