AI synopsis

What people are saying

Discussions reflect a moderate level of interest with references to past research, like the studies from 2005, and mechanisms involving immune responses. Phrases like 'bioactive peptides' and mentions of absorption processes demonstrate thoughtful engagement and recognition of the study’s potential implications for understanding how food-derived collagen impacts human health.

AgreementModerate agreement

Most discussions accept the findings, emphasizing the significance of collagen peptides being absorbed into human blood.

InterestModerate interest

Participants show moderate interest by referencing prior studies and mechanisms, but don't express strong enthusiasm.

EngagementModerate engagement

There is active engagement through sharing related research and discussing biological mechanisms, indicating a genuine curiosity.

ImpactModerate impact

The discussion recognizes potential implications for nutrition and health, suggesting a positive view on the study's relevance.

Abstract in brief

  • The study found that after humans ingested gelatin hydrolysates from sources like pig skin and chicken cartilage, specific collagen-derived peptides appeared in their blood, with levels peaking roughly 12 hours later.
  • The most prominent peptide detected was Hydroxyproline (Hyp) in its peptide form, which increased significantly post-ingestion, indicating successful absorption of these collagen peptides into the bloodstream.
  • Other collagen-related peptides, such as ProHyp, AlaHyp, AlaHypGly, and LeuHyp, were also present in smaller but detectable amounts, suggesting a variety of collagen peptides can be absorbed from food sources.]

Studies in animals and humans have shown that consuming collagen leads to the appearance of several bioactive collagen peptides in circulation. 4/n https://t.co/hTzar9XeB7 https://t.co/pz0ciw5jGj

@DoctorKarl @ProfCCollins https://t.co/njgU4iKdF4 measured increased Hyp and Hyp di/tripeptides in blood after collagen ingestion. Another mechanism in the Barati review is based on oral tolerance with sampling of protein content by the gut immune system, which wouldn't need absorption into blood.

佐藤先生の2005年の論文にもコラーゲンペプチドの経口摂取前から血中にコラーゲンペプチドが検出されている個体（ヒト）のデータが掲載されています。（下図は当該データを赤色にし赤矢印を追加したもの） 論文中には言及がなかったのですが、興味深いと思いました。

@ScepticalDoctor Different studies may report varying percentages of collagen broken down into peptides vs. amino acids, depending on factors such as the hydrolysis method. https://t.co/zgeulAZCNR This graph compares Free Hydroxyproline vs. Peptide HYP (roughly 3:1 ratio). https://t.co/Jx9wadxjac
