There is certainly truth in the idea that one would rather not consume pesticides when eating food, but hey at least bananas have a thick skin. It must be better for you than eating say strawberries or grapes. This might be one of the few foods where organic doesn’t matter much.
But hold on! The real reason to buy organic bananas is for the workers. Trabajadores in countries like Dominican Republic and Guatemala have to deal with a chemical barrage every day they work with the bananas. Workers on organic farmers are free from that daily assault on their bodies.
That is why I buy organic bananas
