Bananas don’t seem overly sweet when just turning yellow, but the sugar content rises as they ripen. A medium ripe banana usually has about 14 grams of sugar. As the skin turns brown, the starch changes into sugar, making it taste even sweeter. Bananas are a favorite for quick energy, especially before exercise. Bananas are not just sweet; they are also rich in potassium, vitamin B6, and dietary fiber. Athletes often eat them for quick energy during workouts or competitions, relying on their natural sugars for fuel. In many countries, bananas are a daily staple, eaten fresh, baked into breads, or blended into smoothies.
