## Summary

Spermidine, a compound found in foods like wheat germ and aged cheese, may help slow liver scarring. In mice and lab studies, it changed how key liver cells talk to each other, reducing fibrosis. Human dietary data also linked higher spermidine intake to lower fibrosis risk.

## Practical Takeaway

This study suggests dietary spermidine may be associated with lower liver fibrosis risk, though human trials are needed.
