“All you need is love.
But a little chocolate now and then doesn't hurt.” Charles M. Schulz
By Alex P. Vidal
IS too much chocolate-eating dangerous to our health?
Can it cause diabetes and obesity as feared?
Over-eating of chocolate can be tantamount to slow
motion suicide, although it contains health benefits if we eat moderately.
Some of the health benefits of chocolate are:
--Cacao, the source of chocolate, contains
antibacterial agents that fight tooth decay. However, chocolate with high sugar
content will negate this benefit, according to Cocosymposium. Dark chocolate
contains significantly higher amounts of cacao and lower amounts of sugar than
white chocolate, making it more healthful.
--The smell of chocolate may increase theta brain
waves, resulting in relaxation.
--Chocolate contains phenyl ethylamine, a mild mood
elevator.
--The cocoa butter in chocolate contains oleic acid,
a mono-unsaturated fat which can raise good cholesterol.
--Men who eat chocolate regularly live on average
one year longer than those who don’t.
--The flavanoids in chocolate help keep blood
vessels elastic.
--Chocolate increases antioxidant levels in the
blood.
--The carbohydrates in chocolate raise serotonin
levels in the brain, resulting in a sense of well-being.
The health risks of chocolate are:
--Chocolate may contribute to lower bone density.
--Chocolate can trigger headaches in migraine
sufferers.
--Milk chocolate is high in calories, saturated fat
and sugar.
--Chocolate is a danger to pets (chocolate contains
a stimulant called theobromine, which animals are unable to digest).
TIME
Christmas is a time for eating chocolate.
Consumption has come a long way since the first
“eating” chocolate was introduced in England by the Bristol firm of Fry and
Sons in 1847.
Much debate and mythology surround people’s craving
for this confection, which has been blamed on depression, the menstrual cycle,
sensory gratification, or some of the 300 plus chemicals that it contains.
The sensuous properties of chocolate depend on the
fat it contains.
Roger Highfield explains in The Physics of Christmas
that
Cocoa butter can solidify in half a dozen different
forms, each of which has a different effect on “mouthfeel” and palatability.
Form V predominates in the best chocolate, making it
glossy and melt in the mouth.
Unlike other plant edible fats, which are usually
oils, Highfiled explains that cocoa butter is enriched in saturated fatty acids
so that it is solid under normal conditions and has a sharp melting point of
around 34C, just below the temperature.
Heat is absorbed when this occurs, giving a
sensation of coolness on the tongue.
“Another reason we like chocolate is the stimulatory
effects of caffeine and related chemicals. Every 100 grams of chocolates
contain 5 milligrams of methylxanthine and 160 milligrams of theobromine (named
after the cocoa tree, whose botanical name, Theobroma cocoa, means “food of the
gods”). Both are caffeinelike substances,” Highfield points out.
Originally, chocolate was a stimulating drink. The name
is derived from the Aztec word xocalatl, meaning “bitter water.”
PHYSICIAN
In the 17th century a physician from Peru
wrote how it is “good for soldiers who are on guard.”
Highfield stresses that indeed, some people have
suggested that it was Casanova’s favorite bedtime drink—to give him a boost
when he needed it.
Medical textbooks do note, however, that when taken
in large quantities, these stimulants can induce nausea and vomiting.
This effect can also be observed in children (and
others) who of overindulge on Christmas Day.
He cites that every 100 grams of chocolate also
contains 660 milligrams of phenylethylamine, a chemical relative of amphetamines,
which has been shown to produce a feeling of well-being and alertness.
“This may be why some people binge on the stuff
after an upsetting experience—or perhaps to cope with the stress of Christmas
shopping,” Highfield theorizes.
He also observes the following:
-Phenylethylamine may trigger the release of dopamine,
a messenger chemical in the brain that plays a role in the “reward pathway”
that governs our urge to eat or have sex.
-Phenylethylamine raises blood pressure and heart
rate, and heightens sensation and blood glucose levels, leading to the
suggestion that chocoholics “self-medicate” because they have a faulty
mechanism for controlling the body’s level of the substance.
However, if a person consumes too much phenylethylamine
or has an inability to remove it due to the lack of a key enzyme (monoamine
oxidase), blood vessels in the brain constrict, causing a migraine, according
to Highfield.
CANNABIS
More recently, it has been found that chocolate also
contains substances that can act like cannabis on the brain, intensifying its
other pleasurable effects.
Highfield says three substances from the N-acylethanolamine
group of chemicals can mimic the euphoric effects of cannabis, according to a
study by Daniele Piomelli, Emmanuelle di Tomaso, and Massimiliano Beltramo of
the Neurosciences Institute in San Diego.
Their works date back in 1990, when scientists found
a site in the brain that responds to cannabinoids, the class of compounds that
include the active ingredient in cannabis.
Recently they have discovered the specific
substances in the brain that bind to this site. One is a fatty molecule dubbed
anandamide after the Sanskrit word for “bliss.”
Piomelli investigated chocolate, which is rich in
fat, because he correctly suspected that it might contain lipids related to
anandamide.
Piomelli was first inspired to look into the
mood-altering effects of chocolate when he became addicted to the stuff one
gray winter in Paris.
Now that he has moved to California, which is as
sunny as his homeland of Italy, he is no longer a chocoholic.
