: 我只想说......
: 营养师朋友说:人体胃酸比胶原蛋白强
: 所以那种吃的胶原蛋白都吃心安的
: 请自行google新闻喔~啾咪

A new view concerning the effects of collagen hydrolysate intake on skin
properties / Vivian Zague
"Iwai et al. [10] reported that a considerable amount of
CH-derived hydroxyproline in a peptide form appeared in
blood of healthy human volunteers who ingested CH from
porcine skin, chicken feet, and cartilage after 12 h of fasting."
CH = collagen hydrolysate
10.引用文献 Iwai K, Hasegawa T, Taguchi Y et al (2005)
Identification of food-derived collagen peptides in human blood after
oral ingestion of gelatin hydrolysates. J Agric Food Chem 53:6531–6536.
吃下去的胶原蛋白其实是可以被吸收(peptide 型式),出现在血液里头
而这peptide有没有活性,能不能改善皮肤? 还需要再证明
"However, there are no data relating the structure of food-derived collagen
peptides and their mechanisms for improving skin properties."
其实这篇review动物实验已经有效果了,只是在人身上是否能复制相同结果就不知道了
不过这篇是2008年的,搞不好现在已经吵完了也说不定 XD
