Banana Peels: The Tropical Gold Mine You’re Tossing

Unlike your regular banana flesh, the peel packs vitamin A, B vitamins, lutein (an antioxidant that supports eye health), other antioxidants, and substantial amounts of soluble and insoluble fiber. What’s shocking is that green banana peels are even healthier than their yellow counterparts. Green peels contain many probiotics and resistant starch, a carbohydrate variety that mimics dietary fiber. This starch helps manage blood sugar levels and fosters a prolonged sense of fullness. While the texture might seem off-putting at first, chefs around the world commonly leave the banana peels on when cooking.
