As bananas ripen from green to yellow to brown, their starches turn into natural sugars, making them sweeter, softer, and easier to digest. Brown bananas also contain higher levels of antioxidants like dopamine and catechins, along with more vitamin C and B6, which support immunity and overall health.
However, their higher sugar content can raise blood glucose more quickly, so they’re best enjoyed in moderation—especially for people managing blood sugar. While often overlooked, brown bananas are nutritious, gentle on digestion, and a healthy choice when matched with individual dietary needs.
