Bananas are a nutritionally complex and unique fruit, possibly because they don’t come from a tree at all, but a giant fruiting herb, the world’s largest.
Bananas are the only fruit to contain all the major vitamins. They’re high in dietary fibre, potassium and magnesium, and have two to three times more carbohydrate than other fruits, but no fat.
Despite its creamy texture, the average banana contains only 501kJ (weight for weight, about the same as cottage cheese).
Best of all, bananas may help make you feel good. According to Peter D Kramer, author of Listening to Prozac, “Serotonin [a brain neurotransmitter] is known to affect sleep, appetite and the like. Raising the level of serotonin seems to enhance security, courage, assertiveness, self-worth, calm, resilience. It makes people feel safe.”
Bananas, among other foods, stimulate the production of serotonin.
