It's not really healthy to eat ripe bananas period. Ripe bananas have a higher glycemic load than maple syrup and plain white bread, and the idea that bananas are especially high in potassium is basically a lie.

Glycemic load is not everything, the total amount of carb is much more important. Eating one ripe banana is comparatively more healthy than a meal full of carbs (e.g. a plate of pasta). Now if you eat fruits and drink juice all day long that's a problem...

It's also perfectly healthy to eat a ripe banana if you are doing a physical activity, as the insulin spike will likely help your muscles use the sugar and you won't store it.

So you eat unripe (green) bananas?
