When the intestinal lining breaks down, harmful gut bacterial antigens can slip into the bloodstream alongside nutrients. This breach in the gut’s protective barrier, known as “leaky gut,” is more than a digestive issue—it’s a sign of inflammatory bowel disease (IBD) and has been increasingly linked to a number of chronic conditions.

A team of researchers working in the lab of UNLV cellular biologist Prasun Guha has uncovered a key mechanism underlying leaky gut and identified a promising and natural way to repair it. And a potential solution is already in many of the foods we eat every day.

In a study published in the journal Nature Communications, the team shares how phytic acid (or InsP6), a natural compound found in whole grains, beans, lentils, nuts, and seeds, plays an important role in maintaining the integrity of the intestinal barrier.
