The colors of bananas

The secret is to prefer green bananas rather than ripe or yellow according to your needs and it is important to know that the nutritional value of bananas changes with ripening.

Basic truth is that the riper the bananas, the sweeter they are. This is because the enzymes contained in them convert to starch and when the fruit ripens, this starch is converted into mono and disaccharides such as sucrose, glucose and fructose (simple sugars). It is precisely when the starch turns into simple sugar that the ripe banana is also easier to digest. However, several studies have found that when they ripen, bananas lose some of their vitamins and minerals.

Conversely, when the banana is ripe, it also produces various antioxidants and anticancer properties, while when it is completely yellow or has dark spots, it produces a substance called TNF (tumor necrosis factor), which has the ability to fight malignant cells.

Therefore, for most people it is more convenient to consume bananas when they are fully ripe, especially well yellow and with spots on their skin. However, people who suffer from diabetes are either at risk or just want to avoid a rapid rise in sugar levels, can include bananas in their diet, but when they are still green.
