Yes, all fruits are good for you.
Bananas provide a number of essential vitamins and minerals that your body needs to function well. Bananas also contain high levels of potassium, which is very helpful in the prevention and reduction of headaches and blood pressure. Bananas also contain tryptophan, an amino acid that helps your brain produce serotonin to help you avoid depression and lessen anxiety. Furthermore, bananas have low-glycemic index so they won’t cause spikes in insulin levels like other carbohydrates might do, keeping you feeling fuller for longer than other foods would without too much sugar or fat build up on your stomach lining either.
Moral of the story: always eat fruit! Especially bananas! They’re healthy AND delicious :)..
