Native to Southeast Asia, bananas are probably one of the most consumed fruit in the world. They are now grown in many warmer parts of the world. They are full of vitamins, nutrients, fibers, minerals and natural sugars containing about 105 calories on average. Moreover, they are free of saturated and trans fat and cholesterol. By eating a banana you can indulge your sweet tooth without ruining your waistline.
There are many types of bananas available, which vary in color, size and shape. The most common type is the yellow banana, which is green when unripe. The riper the banana, the better it is. In fact, this means that the riper bananas contain more Tumor Necrosis Factor, (TNF). This substance can fight abnormal cells and this anticancer property increases as the banana ripens. TNF is a cytokine, discharged by specific cells in the immune system of the body and can influence different cells. This property is very efficient for the battle of anomalous cells. According to various studies, riper bananas with TNF slow down tumor growing and even stop it by creating apoptosis cell death. Moreover, due to the high levels of antioxidants, bananas can boost the immune system and the white blood cells.
