Low-Fiber Diets Linked to Gut Lining Damage by Bacteria

Two recent studies published in the Proceedings of the National Academy of Sciences and Nature Metabolism reveal that gut bacteria damage the intestinal mucus lining when deprived of fiber.

Researchers found that in the absence of plant fiber and Proteins Imitating Fibre, gut microbes consume the host's protective mucus, producing harmful phenols instead of beneficial anti-inflammatory compounds.

The findings suggest that consuming plant-based foods is essential for microbial metabolism, as these nutrients help bacteria produce antioxidants that protect intestinal cells from stress.
