..... However, if you eat a carbohydrate-rich meal, your body triggers a release of insulin. This, experts say, causes any amino acids in the blood to be absorbed into the body -- but not the brain. The exception, however, is tryptophan, which remains in the bloodstream at high levels following a carbohydrate meal. This means it can freely enter the brain and cause serotonin levels to rise.

What can also help: Getting an adequate supply of vitamin B-6, which can influence the rate at which tryptophan is converted to serotonin. Vitamin B6 is found in foods such as pork, chicken, turkey, fish, bread, oatmeal, wheat germ, rice, eggs, vegetables, soya beans, peanuts, milk, potatoes and some fortified breakfast cereals.
