Bananas are one of the meals that may be eaten without reservation during supper. Some experts even recommend eating this fruit an hour before bedtime to enhance sleep. It does, indeed, include: minerals (potassium, magnesium) that promote muscle relaxation; and tryptophan, an amino acid that allows the production of serotonin, which is required for the production of melatonin, a hormone that regulates sleep. It's not without cause that the banana is known as "the meal of good mood" in Australia. It includes, among other things: vitamin B6, which is involved in the release of neurotransmitters involved in mood modulation, such as serotonin and dopamine; magnesium, which is necessary for nerve impulse transmission; and tryptophan, a natural antidepressant.
