Banana
Overview
Why eat a banana?
A banana is portable, quick energy wrapped in its own packaging, giving about 112 calories per 126 g serving along with fiber, potassium and vitamin B6. It is one of the easiest ways to add fruit to a busy day, whether that is before a workout, in oatmeal or blended into a smoothie.
Good to know: Bananas are naturally sugary at about 12 g of sugar per 100 g, so if you are watching blood sugar, pairing one with nuts, yogurt or peanut butter makes for a steadier snack.
Potassium for blood pressure
One 126 g banana supplies 451 mg of potassium (10% DV), a mineral that helps balance sodium and supports normal blood pressure and muscle function.
Notable vitamin B6
With 0.37 mg of vitamin B6 per 100 g (22% DV), bananas help the body process amino acids and make neurotransmitters and red blood cells.
Fiber with the sweetness
At 3.3 g of fiber per serving (12% DV), bananas slow digestion a little and feed gut bacteria, which is linked to better digestive comfort.
