WHAT TO EAT
Eating foods that are high in carbohydrates, such as pasta, potatoes, cereals and bread boosts the production of serotonin. The carbohydrates absorb the tryptophan, which in turn is converted into serotonin in the brain thus encouraging feelings of calmness and relaxation. It is claimed that these effects occur within half an hour of eating a carbohydrate snack and seemingly last for several hours.
However, a meal rich in protein can counteract the calming affects awarded by carbohydrates. This is because high protein foods contain several different types of amino acids (including tryptophan and tyrosine) that swamp the system when eaten and they all compete to get to and stimulate the brain. Tryptophan is a large amino acid meaning that only small amounts make it through thus resulting in the creation of only small amounts of serotonin. Consequently, this can cause a sleepless night or lower ones feelings.
On the other hand, eating carbohydrates means that fewer aimino acids are released thus lowering the competition. The pancreas creates insulin when we eat carbohydrates and the insulin directs most of the amino acids into the blood stream, which are then absorbed by the body cells. Since Tryptophan is the larger amino acid it remains in the blood stream ensuring that it has easier access to the brain. Therefore, the serotonin levels are increased making one feel more relaxed and focused.
