Mature bananas produce a TNF substance (tumor necrosis factor) which fights against cells that are different, or tumor cells.
Japanese researchers find that exactly the bananas with black spots are eight times healthier than green bananas or other berries. Compared to grapes, apples, watermelons, pineapples and pears, bananas have the most anticancer ingredients, writes “Amazing stories around the world”.
The more black spots, the more enriched cells that develop immunity. Then the banana is best for digestion because sugar is most easily absorbed, and in its “young” days, starch is not yet turned into sugar.
