15 Nov 2018 --- A Cranberry Institute and USDA-funded study into the potential protective effects of cranberries on the gut microbiome has found that adding cranberries to a meat-based diet can reduce the rise in secondary gut bile acids that have been associated with colon and GI cancer. The feeding trial – published in The Journal of Nutritional Biochemistry – found that the addition of whole cranberry powder to this common diet lessened potentially carcinogenic secondary bile acids and blunted the decline in beneficial short-chain fatty acids (SCFA) in the gastrointestinal (GI) tract.
