The Mood Food ConnectionWhat you eat can affect your mood and how well your brain works.
Minor tweaks in your diet can help you control your moods; at least temporarily, by influencing the level of certain brain chemicals called neurotransmitters.
Meal Size and Mood Response
Meal size can effect mood response. Large meals have shown to reduce mental alertness and performance is the size of a meal. This is especially true for meals containing large amounts of fat, since fat can slow down food absorption. When food absorption is slowed blood flow to the stomach is increased for a longer period of time, resulting in less blood flow to the brain. The result is a very calming effect on the body, resulting in drowsiness, sluggishness, and less ability to focus and concentrate.The food-mood response is short term. Eating a steak at dinner may increase alertness and concentration for two to three hours after eating. Eating a large pasta meal however, produces the opposite effect' a calming response for two to three hours following the meal. Combing both in a single meal can actually counteract the individual effects of these foods.
Neurotransmitters Effects on the Body and Mind
People are more alert when their brains are producing the neurotransmitters dopamine and norepinephrine. People are more relaxed and calm when producing the neurotransmitter serotonin. A stable brain serotonin level is associated with a positive mood state; while reduced serotonoin can result in a depressive state. Of important note is the effect of co-factors on neurotransmitters and resulting mood. Cofactors that are involved in the synthesis of these neurochemical transmitters that can affect neurotransmission include Vitamin B6, zinc and magnesium. They are cofactors in the enzyme aromatic acid decarboxylase, which converts dihydroxy-phenylalanine to dopamine and 5-hydroxytryptophan (5-HTP) to serotonin. Thus a deficiency in vitamin B6 can result in a decrease of a particular neurotransmitter.
Positive Moods and Stress Reduction
Another group of chemicals that can influence mood and appetite are the endorphins. These are the body's natural opiate-like chemicals that produce a positive mood state, decreased pain sensitivity, and reduced stress. Endorphins are released when a person is in pain, during starvation, and during exercise.
A food substance related to endorphins is phenylethylamine, which is found in chocolate.
Calming vs. Energy Foods
Serotonin Producing Foods.Foods that increase the production of serotonin in the brain and have a calming effect on the body are foods that are high in carbohydrates (e.g., pasta, rice, candy, grains, fruits, etc.). These foods raise levels of serotonin, and temporarily will have a calming effect on the mind and body. Carbohydrates affect brain serotonin because they increase the amount of tryptophan in the brain. Tryptophan is the amino-acid precursor of serotonin. It is this diet-neurotransmitter relationship that can help explain why many people may feel drowsy in the afternoon after eating a large carbohydrate meal. The subsequent rise in serotonin in the brain is what lead to drowsiness. The following foods increase serotonin levels which contribute to a calming, anti-anxiety mood:
- Chocolate.
- Oatmeal
Dopamine and Norepinephrine Producing FoodsDopamine and norepinephrine are two other important brain chemicals that appear to be influenced by foods. Both dopamine and norepinephrine are part of the "fight or flight" chemicals that can increase alertness, increase reaction times, and increase concentration. Levels of dopamine and norepinephrine are increased by the consumption of protein-rich foods. The following foods increase dopamine and norepinephrine levels which contribute increasing alertness, focus and decreasing drowsiness:
