A diet rich in plant-based foods, on the other hand, with an abundance of dietary fibre and bioactive substances such as polyphenols, lowers intestinal hypermeability (leaky gut). Vegetables, fruits, legumes, whole grains, cereals, nuts, and turmeric, for example, decrease inflammation and enhance gut health. Fiber also helps reduce constipation - which can lead to increased intestinal permeability. Turmeric contains a compound called curcumin that has many health benefits. Studies have shown it to be effective in treating irritable bowel syndrome (IBS), chronic diarrhea, celiac disease, inflammatory bowel disease (IBD), and more. It may also be useful in preventing cancer. However, much more research is needed on the effects of curcumin before any definitive conclusions can be made about its usefulness for treating or preventing illness. In conclusion, turmeric can help maintain healthy intestinal permeability by reducing constipation and inflammation. This, in turn, may help prevent the leakage of bacteria, toxins, and other substances into the body that can cause illness.
