It is a known fact thatone of the keys to a restful night’s sleep is to calm your brain down rather than rev it up. Thus eating a high-protein meal without carbohydrates may keep you awake. Protein-rich foods perk up the brain because they contain the amino acid, tyrosine. (Tryptophan is the amino acid that the body uses to make serotonin), the neurotransmitter that slows down nerve traffic calming your brain functions.
For students and working adults, high protein, medium-carbohydrate meals eaten for breakfast and lunch, help to keep the body active, and avoided at dinner will help you sleep. Some bedtime snacks you might try are apple pie and ice cream, whole-grain cereals with milk, hazelnuts, tofu and peanut butter sandwiches. The idea is to eat foods high in carbohydrates and calcium, and medium-to-low in protein.
