The idea of digestive tract support from black beans may sound surprising. Many people think about black beans (and beans in general) as problem causing foods in the digestive tract, perhaps largely because of gas production. But recent research has shown that black beans actually provide special support in the lower large intestine (colon) where gas if often produced. The indigestible fraction (IF) in black beans has recently been shown to be larger than the IF in either lentils or chickpeas. It is the perfect mix of substances for allowing bacteria in the colon to produce butyric acid.
