Green Bananas: Why Some Never Ripen and What It Means for Your Health
Some bananas stay green because they’re harvested immature or exposed to cold storage, which can disrupt the normal ripening process. Green bananas have more resistant starch, which digests slower and can be gentler on blood sugar, while ripe bananas taste sweeter as starch converts to sugars. Optimal storage is about 56–59°F to minimize ripening disruption. Both green and ripe bananas provide nutrients like potassium and vitamin B6, so the best choice depends on individual health goals and tastes.
