Thanks to their low sodium and high potassium content, bananas are particularly good for people with high blood pressure. Bananas also contain tryptophan, which the body converts into serotonin, a brain chemical that helps you relax, improves your mood, and makes you fall asleep more easily. That’s why some doctors suggest eating a banana an hour before sleep.
At roughly 105 calories, a medium banana is the perfect size for a mid-morning or mid-afternoon snack. Bananas also provide an abundance of natural sugars, making them a great source of easily digested and readily available fuel.
