Bananas have the ability to improve the overall functioning of the digestive system. This is due to their fiber content, which is present in both soluble and insoluble forms. Fiber on numerous occasions has been proven by scientist to have beneficial effects on the digestive system. It can stimulate the peristaltic action of the gut – which can help fight constipation by facilitating the movement of stool down the colon.

Fiber also stimulates the production of digestive juices, which help break down food particles. Its presence in the gut also improves the growth and proliferation of beneficial microorganisms, where the resistant starch found in it serves as food for these organisms (2).

Bananas also contain reasonable amounts of vitamin C, which has been associated with a reduced risk for gout by numerous scientific researches (5).

Moreover, banana contains copper. Iron is directly involved in the production of red blood cells, while copper and vitamin C assists its absorption into the body.

The relationship between copper and iron is very profound. In fact, there are cases where iron-deficiency anemia cannot be relieved by the consumption of iron but can be successfully treated by the consumption of copper (6).
