Knowing How Food Affects Mood for you and your
clone
Good morning! Time to wake up, roll out of bed, and
sleepwalk into the kitchen for a cup of coffee.
Good afternoon! Time for a moderate glass of whiskey or
wine to soothe away the tensions of the day.
Good grief! Your lover has left. Time for chocolate, lot
of chocolate, to soothe the pain.
Good night! Time for milk and cookies to ease your way
to Dreamland.
For centuries, millions of people have used these foods
in these situations, secure in the knowledge that the food
will work mood magic. Today, modern science knows why.
Having discovered that our emotions are linked to our
production or use of certain brain chemicals, nutrition
scientists have been able to identify the natural chemicals
in food that change the way you feel by
Influencing the production of neurotransmitters
Hooking onto brain cells and changing the way the cells
behave
Opening pathways to brain cells so that the other
mood-altering chemicals can come on board
The following chemicals in food are those most commonly
known to affect mood:
Alcohol is the most widely used natural relaxer: Contrary
to common belief, alcohol is a depressant, not a mood
elevator. If you feel loosey-goosey and exuberant after one
drink, it's not because the alcohol is speeding up your
brain. The chemical actually relaxes your controls, the
brain signals that normally tell you not to put a lampshade
on your head or take off your clothes in public.
Anandamide is a cannabinoid, a chemical that hooks up to
the same brain receptors that catch similar ingredients in
marijuana smoke. Your brain produces some anandamide
naturally, but you also get very small amounts of the
chemical from (what else?) chocolate. In addition,
chocolate contains two chemicals similar to anandamide,
which slow the breakdown of the anandamide produced in your
brain, intensifying its effects. Maybe that's why eating
chocolate makes you feel very mildly mellow. Not enough to
get you hauled off to the hoosegow or bring in the Feds to
confiscate your candy; just enough to wipe away the tears
of lost love. (Don't worry; you'd need to eat at least 25
pounds of chocolate at one time to achieve any
marijuana-like effect.)
Caffeine is a mild stimulant that
Raises your blood pressure
Speeds up your heartbeat
Makes you burn calories faster
Makes you urinate more frequently
Causes your intestinal tract to move food more quickly
through your body
Caffeine also is a mood elevator. While it increases the
level of serotonin, the calming neurotransmitter, it also
hooks up at specific receptors normally reserved for
another naturally occurring tranquilizer, adenosine. When
caffeine latches in place of adenosine, brain cells become
more reactive to stimulants, such as noise and light,
making you talk faster and think faster.
Tryptophan is an amino acid, a group of chemicals commonly
called the building blocks of protein. Glucose, the end
product of carbohydrate metabolism, is the sugar that
circulates in your blood, the basic fuel on which your body
runs. Mile and cookies, a classic calming combo, owe their
power to this, the tryptophan/glucose team.
Start with the fact that the neurotransmitters dopamine,
norepinephrine, and serotonin are made from the amino acids
tyrosine and tryptophan, found in protein foods. Tyrosine
is the most important ingredient in dopamine and
norepinephrine, the alertness transmitters. Tryptophan is
the most important ingredient in serotonin, the calming
neurotransmitter.
All amino acids ride into your brain like little trains on
tiny chemical railroads. But Mother Nature — clearly
a party animal! — has arranged the switches so that
your brain makes way for the bouncy tyrosine train first
and the soothing tryptophan train last. That's why a
high-protein mean heightens your alertness.
To move the tryptophan train up the track, you need
glucose. That means that you need carbohydrate foods. When
you eat carbs, your pancreas releases insulin, a hormone
that enables you to metabolize the carbs and produce
glucose. The insulin also keeps tyrosine and other amino
acids circulating in your blood so that tryptophan train
can travel on lots of open tracks to the brain. With more
tryptophan coming in, your brain can increase its
production of soothing serotonin. That's why a meal of
starchy pasta (starch is composed on chains of glucose
molecules) makes you calm, cool, and kind of groovy.
Some foods make you more alert (such as meat, fish, and
poultry) or calm you down (such as pasta, bread, potatoes,
rice, and other grains), depending on their ability to
alter the amount of serotonin available to your brain.
Phenylethylalanine — sometimes abbreviated PEA
— is an amino acid that your body releases when you
are in love, making you feel, well, good all over. A big
splash occurred in the late 1980s, when researchers
discovered that chocolate, the food of lovers, is a fine
source of PEA. In fact, many people think that PEA has a
lot to do with chocolate's reputation as of the food of
love and consolation. Of course, to be fair about it,
chocolate also contains the mood-elevator caffeine, the
muscle stimulant throbromine, and the cannabinoid
anandamide.
