If you eat bananas every day, what happens to your body?

Eating a banana daily could help your brain function

It has been shown that our diet directly affects our brain health, and a diet that is rich in vitamins and minerals can improve our brain's function (via Healthbeat). This healthy function can be greatly enhanced by the great amount of vitamin B6 in bananas. From eye health to cancer prevention, vitamin B6 is essential to our health, as Healthline explains. In addition to improving brain function and regulating positive mood, vitamin B6 has a number of other brain-specific benefits as well. The long-term effects of vitamin B6 on Alzheimer's disease are still unclear, but research suggests that it may also be helpful. My Food Data estimates that a cup of banana slices provides 32 percent of a person's recommended daily allowance of vitamin B6.
