If you need to stay calm, bananas can help.
Let’s say at school you are having a test or some kind of presentation, and you are very stressed out. You should eat a banana before, they reduce PMS symptoms, bloating and they help you relax. Bananas lower you blood glucose, which keeps you anxiety levels lower.
In the expression “An apple a day keeps the doctor away” the fruit apple should actually be changed to “a banana”.
