Discovered: an amino acid that helps the gut heal itself

Every few days, your gut rebuilds itself completely - cell by cell, guided by signals we still don’t fully understand. For years, scientists have known that diet can influence this process, but the exact messenger between what we eat and how the gut heals has remained a mystery.

In this episode, we look at new research from MIT that uncovers a surprising link between diet, the immune system, and regeneration in the intestine. It’s a story about how a single nutrient can activate immune cells to release molecules that tell the gut when it’s time to repair.

It challenges the way we think about food, not just as fuel, but as information. Because the gut isn’t just digesting what we eat… it’s listening.
