Gut Health

Emerging research on the gut microbiome suggests that walnuts may be one food to consider for gut health due to their prebiotic and possible role in providing a variety of associated health benefits.

A study from the USDA and University of Illinois, published in The Journal of Nutrition, found that walnut consumption was associated with positive changes to the gut microbiome. A small sample of 18 healthy adults (ages 35-68) who ate 42 grams (about 1.5 ounces) of walnuts each day for 3 weeks experienced a decrease in secondary bile acids, which may play a role in colon cancer, inflammation, and gastrointestinal diseases. The study also found that eating walnuts resulted in an increase in gut bacteria that is thought to be beneficial for health.
