Don't throw out your brown bananas!
As a banana turns brown, its concentration of antioxidants increases. Antioxidants are important in helping to protect your body against disease-causing inflammation. In brown bananas, the starches transform into simple sugars. Because a brown banana is mostly simple sugar, it's easier to digest. Plus, it tastes sweeter making it an excellent addition to some recipes in place of sugar as a healthier substitution.
