Heart-Protecting PropertiesFlavanols Dilate blood vessels Boost blood flow to the brain
for 2-3 hours Protect against build-up of
plaque in arteriesVitamins D&E Reduce high blood pressure

Stimulating PropertiesAnandamide Neurotransmitter Dark chocolate = best source of anandamide Derived from “ananda”
meaning “bliss” Binds to cannabinoid
receptors Same as the active
ingredient (THC) in marijuana but has a much milder effect
![Page 8: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/8.jpg)
Stimulating PropertiesAnandamide Slips easily across the blood-brain barrier Anxiety relief, appetite enhancement Form of forgetfulness that may be part of
the brain’s system of getting rid of unimportant or unpleasant memories
Chocolate also contains two chemicals that slow the normal breakdown of anandamide so that it has a prolonged effect
![Page 9: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/9.jpg)
Stimulating Properties
Fun Fact!
Endorphins are also
triggered by music
and laughter.
Endorphins Hormone Binds to opiate receptors Controls pain, stress,
frustration Generates feelings of pleasure

Stimulating PropertiesSerotonin Neurotransmitter Chocolate is a good source of
tryptophan, amino-acid that is the precursor to serotonin
Serotonin causes feelings of pleasure and relaxation
Serotonin further broken down in melatonin, important for causing sleep
Tryptophan
Serotonin
Melatonin
![Page 11: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/11.jpg)
Stimulating Properties Tryptophan naturally found
in proteins; body cannot manufacture its own
Carbohydrates actually best for serotonin production
Tryptophan scarcest of all the amino acids
Carbohydrates increase ratio of tryptophan in bloodstream
Tryptophan
Serotonin
Melatonin

Tryptophan
Serotonin
Melatonin
Stimulating Properties
Fun Fact!
The best way to raise
serotonin levels is through vigorous exercise
Melatonin Hormone that
assists in sleep When eyes stop
detecting light, serotonin is broken down into melatonin

Stimulating Properties
Fun Fact!
Dog’s don’t have enzyme
needed to metabolize
theobromine;
Become highly over stimulated
Phenylethylamine Quickens pulse and makes you
feel alert Feelings similar to falling in love
Theobromine Mild, natural stimulant Molecular “cousin of caffeine Cough suppressant

HEALTH RISKS

Health Risks Chocolate does contain sugar and fat
which provide a lot of calories Weight gain from excessive chocolate
consumption cancels any health and especially heart benefits
MODERATION Recommended daily dose is 3 oz or less
of DARK CHOCOLATE

IS CHOCOLATE ADDICTING?
![Page 17: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/17.jpg)
Is Chocolate Addicting? Acts like a drug on a small scale Influences same parts of brain as
morphine, marijuana, and opiates In a study by University of Michigan
researchers, volunteers’ desire for chocolate was diminished after taking an opiate-blocking drug
![Page 18: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/18.jpg)
What Causes Chocolate Cravings?
1) Low blood sugar Brain sends a signal telling body it needs
fuel Body often misinterprets as cravings for
sugary foods Chocolate provides a “quick hit” of sugar
2) Low serotonin levels Brain recognizes it needs more serotonin Chocolate boosts serotonin levels
![Page 19: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/19.jpg)
What Causes Chocolate Cravings?
3) Stress! Serotonin calms anxiety
4) Culture Especially American women
Complex carbs are best to eat in all these situations!

Why Do Women Crave Chocolate More Than Men?
40% of women experience chocolate cravings
10% of men experience chocolate cravings
7-10 days before menstrual period, women often have lowered serotonin levels
Increased hormone and insulin production lead to low blood sugar
![Page 21: CHocolate](https://reader036.vdocuments.site/reader036/viewer/2022070423/5681668d550346895dda5ad0/html5/thumbnails/21.jpg)
Does Chocolate Relieve Pain From Menstrual Cramps? Cramps are caused by release of hormone
called prostaglandin from lining of uterus Prostaglandin causes uterus to undergo
contractions Inflammatory effect and constriction of blood
vessels cuts off the oxygen supply to uterine muscles, causing pain
Despite chocolate’s pain-relieving properties, its caffeine and theobromine content is thought to aggravate symptoms more than relieve them
