Calories in a Banana

Peeled BananaThe humble banana is one of the best energy foods and a favorite among athletes.

Easy to eat, tastes good, and is wrapped up in a biodegradable wrapper.

However, like most fruits, it has a high sugar content. You should not let this put you off. Bananas have fiber – an essential part of any healthy diet. Greener bananas have more resistant starch, a fiber that your body has a challenge absorbing. This means it will fill you up quicker.
