At about 100 calories a piece, bananas are an excellent source of easy-to-digest sugar and natural electrolytes. They're also a favourite post-event recovery food, and for a good reason: One medium banana contains 422 mg of potassium, which your body needs to regulate fluids and prevent muscle cramps and spasms. Because you sweat out potassium during physical activity, it's important to replenish as soon as possible afterwards.
Bananas are slightly higher in energy than other fruits because the calories come mainly from carbohydrate, which makes them brilliant for refuelling before, during or after a workout.
Bananas contain a lot of B6 (per banana 0,7 mg of vitamin B6) which helps the muscles and nerves to work together in a better way.
If you have a hang-over… take a banana shake. Because of the B6 and potassium, your hangover will be gone in a second…
