Dubbed "Nature's Wonder Fruit", bananas provide the major vitamins thiamine, riboflavin, niacin, folate, beta-carotene and they are the best fruit source of vitamin B6. Bananas naturally are a good source of fibre and potassium while having no fat or cholesterol.
Why is the banana so popular with young people and athletes? It’s because bananas are a quick and easy source of carbohydrate which is needed to provide energy for the muscles and the brain. Let us explain.
Muscle power
What are the best food choices before sport? Food that is high in carbohydrate. These are needed to top up the natural fuel used by muscles in sport. When a muscle is used it burns glucose that has been released from the muscle ‘petrol tank’ called glycogen, which is made from the carbohydrate found in food. If meals are low in carbohydrate, the muscles get low in glycogen, and you will run out of energy before the end of sport.
Favourite high carbohydrate foods are pasta, bread rolls, steamed rice, mashed potato and fruit. The banana is the favourite fruit of so many active young people. They are easy to eat, rich in carbohydrate, and they help you to do your best in sport.
Brain power
To do well in school your brain has to be working well. The fuel your brain uses to think clever thoughts is glucose, the same fuel that your muscles love to use. The glucose in your blood comes mainly from carbohydrate foods like pasta, rice, bread, baked beans and bananas. The glucose in blood is used whenever you think or learn something new. Now you can see why the banana with its carbohydrate, fibre and vitamins can help you to learn better at school.
Myth 1: The banana contains fat.
Despite its creamy texture a banana contains no fat at all. Being a plant food, the banana contains no cholesterol either (only animal foods have cholesterol).
Myth 2: The banana is constipating.
A medium banana provides around 2.5 g of fibre, which is one tenth of the needs of an adult and about one sixth of what a 10 year old needs for good bowel health. Rather than being constipating, the banana is a great help in keeping you regular.
Myth 3: The banana is fattening.
In fact an average banana contains only 376 kJ or 90 Calories, (weight for weight about the same as cottage cheese). And because it's so filling, the banana is ideal for morning recess or as an after school energy-boost.
