The bananas are really delicious and rarely someone can resist them. If you are one of those who enjoy eating bananas, then you should read this article and be careful the next time you buy some. There is one thing you should pay attention to before you decide to indulge in this tasty fruit.
A completely ripe banana produces TNF (Tumor Necrosis Factor). This substance has the ability to fight abnormal cells. According to a Japanese research, this substance found in the banana has anti-cancer properties. So, there is a good reason why Japanese love and consume bananas. According to the same research, the TMF successfully increases the capacity of the immune system. In conclusion, the study suggests that eating ripe bananas may prevent carcinogenesis and lifestyle-related diseases. The riper the banana is more black spots or patches on the skin develop. Those dark spots increase the immunity enhancement quality. As the quality of anti-cancer effects is associated to the level of ripeness of the fruit, the riper the banana is, the better anti-cancer quality has.
It is a well-known fact that as the fruit ripens, the nutrient content quite changes. The levels of antioxidants in the banana increase as the banana itself ripens and becomes yellow. When the banana is completely ripened and it has dark patches on the skin, the nutrient content changes to simple sugars. These sugars are easier to digest.
The bananas that have reached the stage of multiple dark spots on the skin have a significantly bigger amount of TNF. They are believed to be 8 times more effective in enhancing the property of white blood cells than the green bananas or the fresh ones, without the dark patches or spots on the skin.
The TNF ( Tumor Necrosis Factor) is helpful in fighting abnormal cells in the body due to the fact that it is a cytokine, a substance secreted by certain cells of the immune system that have an effect on other cells. The research that was done in regard to the ripening bananas actually proved that the levels of TNF in bananas with dark spots on the skin, before the entire banana turned brown have significantly increased. This research found out that the activity of banana is similar to the activity of Lentinan. Lentinan is a chemical immunostimulant that is administered intravenously as an anti-cancer agent. In conclusion, the ripened banana can act as an anti-cancer agent because it stimulates the production of white blood cells and prevents their mutation.
The experiment conducted by the Japanese scientists actually dealt with various ripe fruits such as banana, apple, grape, persimmon, pear, watermelon and pineapple and tended to prove their health benefits. All of the fruits were compared and the banana gave the best results. The banana significantly enhanced the immunity of the body, produced anti-cancer substance TNF and increased the number of white blood cells.
It is recommended to eat 1-2 bananas on daily basis and thus increase your body immunity to diseases like flu, cold and many others. When the bananas are fully ripen, keep them in the refrigerator in order to reduce further vitamin loss. You can eat them immediately if they are fresh with brown spots on the skin. Avoid over-ripe bananas whose skin is split open or turned completely brown.
