UConn Study Reveals Health Benefits of Walnuts for Colonic Health and Cancer Prevention
A recent clinical trial at the University of Connecticut School of Medicine has found that consuming a handful of walnuts daily may enhance colonic health and aid in cancer prevention. Led by Daniel W. Rosenberg, the study focuses on the benefits of ellagitannins found in walnuts, which convert in the gut to a potent anti-inflammatory agent, urolithin A.
Over three weeks, 39 participants, aged 40 to 65 and at elevated risk for colon cancer, consumed ellagitannin-rich walnuts after eliminating similar foods from their diets. Researchers observed a significant increase in urolithin A levels and a notable reduction in inflammatory markers, particularly in obese patients. This suggests walnuts may positively impact immune cells in colon polyps.
Advanced imaging technology revealed that higher urolithin A levels correlated with reduced proteins associated with advanced colon cancer, indicating walnuts could be instrumental in enhancing colon health. The findings align with earlier studies emphasizing walnuts’ anti-cancer effects.
Rosenberg recommends incorporating walnuts into daily diets for potential long-term health benefits. The study was supported by the American Institute for Cancer Research and the National Cancer Institute.
