The Claim

Lentil-derived polyphenols, particularly from the seed coat, undergo digestion-dependent transformation into bioactive compounds that suppress NF-κB and MAPK inflammatory signaling pathways and activate the Keap1–Nrf2 antioxidant pathway in intestinal epithelial cells, resulting in reduced oxidative stress and improved barrier integrity.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Polyphenols from lentil seed coats are broken down during digestion into compounds that directly reduce inflammatory signaling and activate antioxidant defenses in intestinal cells, leading to lower oxidative stress and stronger intestinal barrier function.

See the scientific wording

Lentil-derived polyphenols, particularly from the seed coat, undergo digestion-dependent transformation into bioactive compounds that suppress NF-κB and MAPK inflammatory signaling and activate the Keap1–Nrf2 antioxidant pathway in intestinal epithelial cells, contributing to reduced oxidative stress and improved barrier integrity.

Why this might work

When you eat lentils, the outer coat breaks down in your gut and turns into new compounds that enter intestinal cells. These compounds block signals that cause inflammation and turn on a defense system that cleans up harmful molecules. This reduces damage to the gut lining and helps it stay tightly sealed.
