Bananas
 
Bananas are good for our health and it is recommended that you should take at least one or two daily. However, do you know that a fully ripe banana produces a substance that's beneficial to our health. This substance is known as TNF (Tumor Necrosis Factor) and it has the ability to fight abnormal or cancerous cells.

As the banana ripens, you will notice that dark spots and patches will develop all over its skin. The more these dark patches and spots that it has, the higher the immunity enhancement quality that it will be. The Japanese people have been known to consume fully ripen bananas particular when they fall ill.

Based on the scientific research conducted by the Japanese scientists, it was found that TNF are known to have anti-cancer properties. The degree of the anti-cancer effect is related to the degree of the ripeness of the fruit. In another words, the riper the banana, the higher or better of the anti-cancer quality.

In an animal experiment that carried out by Professor Senji of Tokyo University, he found that among the fruits that were fed to lab mice, banana produces the best overall health benefits. Other fruits which were used in the experiment includes grape, apple, water melon, pineapple, pear and persimmon. Banana is able to increase the number of white blood cells, enhances the immunity of the body and produces anti-cancer substance, TNF.

Moreover, according to the professor, yellow skin bananas with dark spots and patches on it are eighth times more effective in enhancing the property of white blood cells, as compares to the ones which are still green.

And so it is recommended that you should eat at least one to two bananas daily to increase your body immunity to diseases such as flu, cold, and etc.

Bananas with dark spots
I have even heard that the Japanese will even consume bananas which have already turn black (the whole banana and not just with black spots and patches) when they are really sick, particular when it has something to do with cancer. I used to disbelieve this fact until I have read it myself. So don't throw away bananas which look bad as they might be the cure for your sickness. It might save your life!
