The expression "Going bananas" is from the effects of bananas on the brain. Bananas contain three natural sugars - sucrose, fructose and glucose combined with fiber. A banana gives an instant, sustained and substantial boost of energy and can help us keep fit. It can also help overcome or prevent illnesses and conditions such as nerves. Bananas are high in B vitamins that help calm the nervous system.
A banana is a natural remedy for many ills. When you compare it to an apple, it has four times the protein, twice the carbohydrate, three times the phosphorus, five times the vitamin A and iron, and twice the other vitamins and minerals. It is also rich in potassium and is one of the best value foods around. Bananas might be the reason monkeys are so happy all the time!
