Depression According to a recent survey undertaken by MIND amongst people suffering from depression, many felt much better after eating a banana. This is because bananas contain tryptophan, a type of protein that is known to help you relax, improve your mood and generally make you feel happier.	PMS The vitamin B6 it contains regulates blood glucose levels, which can affect your mood.	Anaemia High in iron, bananas can stimulate the production of haemoglobin in the blood.
Blood Pressure This unique, tropical fruit is extremely high in potassium yet low in salt - very helpful in managing blood pressure.	Brain Power Research has shown that the potassium-packed fruit can assist learning by making pupils more alert.	Constipation Because they are high in fibre, including bananas in the diet can help restore normal bowel action - without resorting to laxatives.
Hangovers It has been said that one of the quickest ways of curing a hangover is to make a banana milkshake sweetened with honey. The banana calms the stomach and, with the help of the honey, builds up depleted blood sugar levels, while the milk soothes and re-hydrates your system.	Smoking Bananas can also be helpful to people trying to give up smoking. The B6 and B12 they contain, as well as the potassium and magnesium found in them, help the body recover from the effects of nicotine withdrawal.	Stress Potassium is a vital mineral, which helps normalise the heartbeat, sends oxygen to the brain and regulates your body's water balance. When we are stressed our metabolic rate rises, thereby reducing our potassium levels. These can be rebalanced with the help of a high-potassium banana snack.
