Bananas contain vitamin C, B6 and potassium. Eating a diet low in sodium and rich in potassium may help decrease the risk of high blood pressure and stroke. Bananas are also a good source of fiber which helps with digestion making you feel full for a longer period of time helping with weight management.

Bananas are an excellent source of potassium and vitamin B6, and a good source of vitamin C, fiber, riboflavin, magnesium, biotin, and carbohydrates. Since they have a lower water content than most fruit, bananas typically have more calories as well as a higher sugar content. A 31/2-oz (100 g) serving is a small (61/2-inch) banana and provides 89 calories, 1.1 g of protein, 0.3 g of fat, and 22.8 g of carbohydrate, with 2.6 g of fiber and 12.2 g of natural sugars (glucose, fructose, and sucrose), 358 mg of potassium, 27 mg of magnesium, and 5 mg of calcium.
