Bananas with dark patches – anti Cancer

over ripe bananaGuess science is only discovering now what grandma knew a hundred
years ago. Bananas with dark patches on yellow skin – Anti Cancer ! The
fully ripe banana produces a substance called TNF which has the ability to
combat abnormal cells.
So don’t be surprised very soon the shop will go out of stock for
bananas. As the banana ripens, it develops dark spots or patches on
the skin. The more dark patches it has, the higher will be its’
immunity enhancement quality . Hence the Japanese love bananas for a
good reason. According to a Japanese scientific research, banana
contains TNF which has anti-cancer properties. The degree of
anti-cancer effect corresponds to the degree of ripeness of the fruit,
i.e., the riper the banana, the better the anti-cancer quality. In an
animal experiment carried out by a professor in Tokyo U comparing the
various health benefits of different fruits, using banana, grape,
apple, watermelon, pineapple, pear and persimmon, it was found that
banana gave the best results. It increased the number of white blood
cells, enhanced the immunity of the body and produced anti-cancer
substance TNF. The recommendation is to eat 1 to 2 banana a day to
increase your body immunity to diseases like cold,flu and others.
According to the Japanese professor, yellow skin bananas with dark
spots are 8 times more effective in enhancing the property of white
blood cells than the green skin version.
