You should be really careful the next time you decide to buy bananas if you enjoy their company. Rarely anyone can resist them because they are so delicious, but there is one thing that you must be aware of before buying these tropical flavor fruits.
Banana that is fully riped produces a substance called TNF (Tumor Necrosis Factor) which has the ability to combat abnormal cells. As the banana ripens, it develops dark spots or patches on the skin. It’s immunity enhancement, quality will be higher the more dark patches it has. Banana contains TNF witch has anti-cancer properties according to a Japanese scientific research. According to their study this substance can help in increasing the immune system capacity. Eating the ripe bananas may just prevent certain lifestyle diseases and carcinogenesis.
Nutrient content of fruits change slightly as they ripen is known for a fact. As a banana ripens it turns yellow and its level of antioxidants increases. The starch content changes to simple sugars that are easier to digest in full ripe bananas with dark spots on skin.
In an experiment carried out by Japanese scientists it was found out that banana increased the number of white blood cells, enhanced the immunity of the blood and produced the anti-cancer substance TNF. The recommendation is to eat 1 to 2 bananas a day to increase your body immunity.
It’s believed that bananas that have brown spots are more effective that the green skin banana or fresher bananas without the same dark patches or spots.
TNF is helpful In fighting abnormal tumor cells in the body. It has been proved that the activity of banana is comparable to that of Lentinan, a chemical immune stimulant that is intravenously administrated as an anti –cancer agent. So ripe banana can act as an anti-cancer agent by stimulating the production of white blood cells In the human cell line and prevent cell mutation.
