Description
What people eat shapes their gut microbes, and a new scoring index rates diets by how friendly they are to those microbes. Yatian Wang, Guoshan Zhang, Shen Lin, and Xiaoyuan Zhuang asked in 2026 whether that score tracks irritable bowel syndrome. Their case-control study covered 350 adults, half with the syndrome and half matched without it.
Patients scored far lower on the gut-friendly diet index than controls. Those with the highest scores had lower levels of several blood markers tied to a leaky gut and inflammation, and they reported milder symptoms. The top third of scores came with much lower odds of having the syndrome. The authors caution that symptoms may change diet rather than the other way round, so forward-looking studies are needed.
