Not Such a Diet Food
Bananas have lots of good nutrients but they are not a diet food. Bananas are higher in calories than other fruits – at about 105 calories – and they have less fiber, so you won’t feel full as long.
A banana might be a good snack, but for calorie counters, there are better snacks out there. They are mid-level on the glycemic index, so diabetics may want to avoid them.
And you probably don’t want to eat a lot of bananas anyway!
