Many people enjoy eating bananas, but the next time they buy some, they should be aware of a few things. The next time you enjoy this delicious tropical fruit, read the text below and use caution.

A fully ripe banana releases a substance called tumor necrosis factor (TNF), which combats aberrant cells. A banana indicates its ripeness by having more dark patches or spots on it. Ripe bananas are better for strengthening the defenses of the immune system. Additionally, Japanese researchers have verified that the TNF present in bananas increases immunity, which helps prevent cancer. Thus, eating bananas can help prevent some illnesses and tumors.

It is also proven that the fruit content changes as it becomes riper. That is why as the banana is riper it becomes more yellow and the antioxidant level increases. In a ripe, with black spots banana the starch turns into sugar which is easier to digest.

Japanese scientists in their experiment have also found that the banana produces TNF (anti-cancer substance), increased number of white blood cells and improves the immune system. It is recommended to consume 1-2 bananas a day to boost the immunity.

Bananas with brown spots are proven to be healthier than the ones with green peel or the fresh ones with no patches or spots.

Cancer cells can be defeated with the help of TNF. The impact that the banana has on the body is linked with the one of Lentinan which stimulates the immunity and is also known as anti –cancer agent. To conclude, ripe banana contains anti-cancer properties because it triggers the white blood cells formation and prevents cell mutations.

Note: In order to prevent vitamin loss, place the fully ripe bananas in a fridge or consume fresh bananas with dark spots immediately.
