How many complex carbohydrates are there in one medium banana?

A medium Banana (120g) carries 24g of Carbohydrate per portion. If not fully ripened (i.e it still has slightly green end points and no brown spots) then it will have a low GI, around 52, therfore its digestion will be slower; thus keeping you fuller for longer and not giving your bodu such a sugar rush. (Its Glysemic load is 12). A bana is great feel good food, and a great pre and post exercise snack (always eat some form of protein with carbohydrates to avoid a "sugar rush" and keep your energy levels constant).
