The Claim
Phosphatidylcholine acyl-alkyl C34:3 may partially mediate the association between physical activity and reduced colorectal cancer risk, accounting for approximately 7.4% of the total effect, though this mediation effect was attenuated with longer time lags.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A specific lipid molecule called phosphatidylcholine acyl-alkyl C34:3 may explain a small portion of why people who are more physically active have a lower risk of colorectal cancer, but this connection becomes weaker when there is a longer delay between activity and cancer diagnosis.

What the research says
1 studyStudy: Identifying Metabolomic Mediators of the Physical Activity and Colorectal Cancer Relationship
This study found that people who are more physically active have higher levels of a specific fat molecule (PC ae C34:3), and this molecule helps explain why being active lowers the risk of colorectal cancer — about 7.4% of the benefit comes from this one molecule.
