小弟原本諗住search下有無D論文會講肉食者同素食者既腸道菌相(microbiota)既比較 但可能關鍵字錯 所以搵唔到
所以我直接搵素食者對於菌相既影響
比較忙我剩係睇下摘要Abstract
呢篇文將素食者同雜食者做對比
Q:「我識人完全唔食菜,條友又無咩事喎」
A: 所有人的菌相都係後天培養,基本上肉食都會有益生菌係條腸入面,但問題佢 好菌同壞菌既比例 同 食纖維既人唔同 極可有能好菌係比較少
篇文有講素食者好菌既比例係高極多
所以推斷攝取大量膳食纖維既人 好菌比例係會提升
例如耳熟能詳既乳酸菌 (Lactobacillus) 同 supplement都會比你既共生菌 比菲氏德菌(Bifidobacterium)
同埋膳食纖維重會促進D 共生菌發揮功能 產生短鏈脂肪酸 提供能量
短鏈同長鏈唔同 可以直接入微血管網到肝 快速提供能量
重有一樣好撚重要既功能 腸入面既菌重會整Vitamin K. (凝血用)
所以肉食者既凝血功能有可能比較弱
另外如果做媽媽 人奶唔夠vita. K既話 個BB會因為缺乏凝血因子 係發育過程內出血死亡
原文:
Additionally, vegans and vegetarians have significantly higher counts of certain Bacteroidetes-related operational taxonomic units compared to omnivores.
Polyphenols, also abundant in plant foods, increase Bifidobacterium and Lactobacillus, which provide anti-pathogenic and anti-inflammatory effects and cardiovascular protection.
Fibers (that is, non-digestible carbohydrates, found exclusively in plants) most consistently increase lactic acid bacteria, such as Ruminococcus, E. rectale, and Roseburia, and reduce Clostridium and Enterococcus species.
High fiber intake also encourages the growth of species that ferment fiber into metabolites as short-chain fatty acids (SCFAs), including acetate, propionate, and butyrate. The positive health effects of SCFAs are myriad, including improved immunity against pathogens, blood–brain barrier integrity, provision of energy substrates, and regulation of critical functions of the intestine.
