Is a Handful of Walnuts a Day the Secret to a Healthier Gut and Colon? Study Sheds Light

New clinical trial results from the UConn School of Medicine reveal that consuming walnuts may reduce systemic inflammation and help lower the risk of colon cancer. The findings, published in Cancer Prevention Research, underscore the health-promoting effects of ellagitannins, polyphenols found in walnuts that are metabolized by the gut microbiome into powerful anti-inflammatory compounds called urolithins.
The research, led by Dr. Daniel W. Rosenberg and a multidisciplinary team at UConn, highlights the unique role of urolithin A—formed in the gut after walnut consumption—as a key anti-inflammatory agent with potential cancer-inhibiting properties. “Ellagitannins in the walnut are importantly providing the anti-inflammatory and anti-cancer properties that we’re seeing in patients in our clinical trial research, particularly the gut’s conversion of ellagitannins to a potent anti-inflammatory agent, urolithin A,” said Dr. Rosenberg, who has studied walnut health benefits for over a decade.
