Am working with a mental health specialist who asked to research foods that affect your mood.

I am a student dietitian from the UK and I am working with the mental health specialist. She has asked me to research on foods that can affect your mood. So far I have had little success and am writing to ask if you know more about this area of dietetics. I would be very grateful if you could contact me with any information you have or possible contacts to try.

Here are a few of the nutrients that affect mood. Carbohydrates (starch, fruit, milk, and desserts) have a major effect on endorphins in the brain. Caffeine (coffee, tea, cola beverages and chocolate) also affects the brain in keeping it awake. Caffeine has a half-life of 5 hours so the stay awake effects last 10 hours. Alcohol (spirits, liquor, wine, beer, liqueur) is a depressant. Tryptophan (turkey and other poultry foods), an amino acid, induces sleep.
