Research into bananas
Maintain digestive function -- Like most fruits, bananas are rich in dietary fiber and can help sweep the colon of accumulated waste. However, a study published in Anaerobe in December 2011 also found that bananas can improve digestive function. The results showed that women who consumed two medium-sized bananas per day demonstrated reduced bloating and greater amounts of beneficial Bifidobacterium gut bacteria, than the control groups. "We concluded that daily consumption of bananas is a well-tolerated eating behaviour, which may induce bifidogenesis in healthy women experiencing body weight problems," wrote the authors.
