Study: A handful of walnuts a day may protect against colon cancer


Walnuts are already an excellent choice for a quick snack or salad topping because they are full of healthy fats and Vitamin D. Now, researchers have found yet another health benefit to eating walnuts: a handful of walnuts a day may help prevent colon cancer.

A study from the University of Connecticut Health Center found that a handful of walnuts per day reduces the risk of getting colon cancer.

Researchers fed mice a diet rich in walnuts and found that mice eating walnuts had fewer tumors. The researchers discovered that walnuts help the growth of good bacteria in the gut, which helps protect against cancer.

“There is accumulating evidence that eating walnuts may offer a variety of benefits related to health issues like cancer. This study shows that walnuts may also act as a probiotic to make the colon healthy, which in turn offers protection against colon tumors,” Daniel Rosenberg, one of the researchers said.

A serving of walnuts per day is an ounce of walnuts, so about a quarter cup or 12-14 walnut halves, according to the California Walnut website. It’s easy to eat a handful of walnuts for a snack or sprinkle walnuts over oatmeal or a salad. If you’re feeling particularly creative, put some walnuts in your food processor and make walnut butter to serve on toast.
