Recent research has shown that black beans provide special support for digestive tract health, and particularly our colon. The indigestible fraction (IF) in black beans has recently been shown to be larger than the IF in either lentils or chickpeas. It has been shown to be the perfect mix of substances for allowing bacteria in the colon to produce butyric acid. Cells lining the inside of the colon can use this butyric acid to fuel their many activities and keep the lower digestive tract functioning properly. By delivering a greater amount of IF to the colon, black beans are able to help support this lower part of our digestive tract. Lowered colon cancer risk that is associated with black bean intake in some research studies may be related to the outstanding IF content of this legume.
