New research has emerged proving that
chocolate is good not only for the soul, but for your mind and body as well.
According to a video released by the
American Chemical Society (ACS), chocolate contains hundreds of compounds, and
many of them come with benefits that go far beyond a few delicious moments of
sweetness.
Studies have already established that
chocolate contains a number of beneficial ingredients. For instance, resveratrol,
an important compound in chocolate, may not only protect your brain and nervous
system, but actually prolong your life.1
Dark chocolate is also an inflammation
fighter, listed along with turmeric and following a Mediterranean-style
diet as one of the healthiest, most natural ways to reduce the inflammatory
processes underlying the chronic, degenerative diseases that afflict most of
the developed world.
Five pieces of evidence highlighted in
the ACS
video show that other factors enhance the sweet, smooth goodness of
chocolate, and those involve naturally occurring chemicals. Read on.
Antioxidants – The
Not-So-Sweet Things Chocolate Has to Say about Free Radicals
One of the most compelling reasons to
make chocolate a part of your regular diet may be for the antioxidants it
provides.
Few foods, and certainly not dessert
foods, have as much therapeutic potential as this “candy” aisle treat, as
evidenced by a wide range of accumulating scientific research linking its
consumption to over 40 distinct health benefits.2
While most of us have heard about the
importance of antioxidants, a primer might help, beginning with the explanation
that the formation of free radicals – atoms, ions and molecules with unpaired
electrons – in your cells can damage your DNA to the point that your risk of
developing diseases like Alzheimer’s, heart disease and cancer are elevated.
This is why the antioxidant polyphenols
in chocolate are so valuable, as they have the ability to stop free radical
mediated oxidation. This helps to decrease your risk of those and other
diseases by directly interfering with one of the major preventable causes of
chronic degenerative diseases.
A factoid from ACS's Journal of Agricultural and Food Chemistry
indicates that naturally occurring polyphenols in cocoa, the fundamental
component in chocolate, actually boost levels of HDL, the "good"
cholesterol, while at the same time reducing the atherogenicity of so-called
“bad” variety – LDL – by preventing its oxidation.3
Supporting evidence from the Cleveland Clinic study4 noted:
"Antioxidants are believed to
help the body's cells resist damage caused by free radicals that are formed by
normal bodily processes, such as breathing, and from environmental
contaminants, like cigarette smoke. If your body does not have enough
antioxidants to combat the amount of oxidation that occurs, it can become
damaged by free radicals. For example, an increase in oxidation can cause
low-density lipoprotein (LDL), also known as 'bad' cholesterol, to form plaque
on the artery walls."Chocoholics Aren't Weak-Willed – They Just Know What Makes Them Feel Good
If you’re one of these individuals who
gets a nice mood boost whenever you sink your teeth into a bar of pure,
unadulterated chocolate, it is not happenstance. There's actually a chemical
reason called anandamide, a
neurotransmitter produced in the brain that temporarily blocks feelings of pain
and depression.
It's a derivative of the Sanskrit word
"bliss," and one of the great things about chocolate is that it not
only produces this compound, it also contains other chemicals that prolongs the
"feel-good" aspects of anandamide.But there’s more to this brain chemical than just how it makes us feel.
As a scientist on the topic, Daniele Piomelli, from the
“Anandamide
is also synthesized in areas of the brain that are important in memory and
higher thought processes and in areas that control movement. That implies that
anandamide's function is not just to produce bliss.”5
Anandamide has been compared to the
sensation derived from marijuana, but Piomelli says "We are talking about
something much, much, much, much milder than a high."6 There’s
also evidence that this compound has the ability to help “sweeten” up your love
life as well.Need a Brain Boost? A Surge of Energy? Reach for Chocolate!
Natural stimulants in chocolate produce
a boost in both physical and brain energy, primarily from caffeine and
theobromine. But one clinical study involving 24 healthy female subjects showed
“synergistic” effects on cognition and mood, which incidentally translated into
improved blood pressure.7 Everyone
knows chocolate contains caffeine, a stimulant that can help heighten physical
energy and alertness, but studies also show that it can inhibit inflammation in
the brain that causes migraines.8
Also regarding brain health, a Johns
Hopkins study found that dark chocolate may shield the brain from damage after
a stroke by increasing cellular signals.9 Mice
which had ingested epicatechin, a compound found in dark chocolate, suffered
significantly less
brain damage after undergoing induced stroke than mice which had not been
given this compound. What this means for ischemic stroke victims (related to
clot obstructions in the vessels supplying blood to the brain, a condition
known as antherosclerosis)10 is that
the epicatechin in dark chocolate may actually protect the brain.
Flavonols are the main flavonoids found
in cocoa and chocolate, as a British study found.11 A pilot
study evaluated the relationship between cerebral blood flow and a dose of
flavanol-rich cocoa, which showed a marked increase in the cerebral blood flow
to gray matter. The study results indicated that the flavonols in cocoa have
the treatment potential against vascular impairment, which leads into the next
point…
Raw Chocolate =
Improved Heart Health… and Other Life-Saving BenefitsAccording to that same study,12 cocoa flavonols could be used to treat problems with vascular impairment, including dementia and strokes.13 Additionally, the ACS studies found that the polyphenols and catechins in chocolate may lower the stroke risk in men. More specifically epicatechins, which help prevent not only clotting but inflammation, is helpful, researchers say, in preventing some types of strokes.
What's interesting is that a 7-study
meta-analysis14 sought
to find a link between chocolate consumption and certain cardiometabolic
disorders, such as coronary heart disease, stroke, diabetes and metabolic
syndrome. Along with those disorders are related problems like hypertension,
elevated fasting glucose and triglycerides, and high cholesterol, abdominal
obesity. But rather than negative effects, scientists found that chocolate –
specifically the dark unprocessed raw cacao kinds – actually reduced
the risk of such disorders.
Don't Worry - Eat
Chocolate
Beyond the fact that chocolate contains
the feel-good anandamide compound, there are additional clinically-confirmed
reasons why chocolate has been referred to as “the
new anti-anxiety drug.” Another ACS study (in the Journal of Proteome Research)
revealed that one-and-a-half ounces of dark chocolate a day for 2 weeks reduced
stress hormone levels. Volunteers for the study, categorized as “highly
stressed,” were found at the end of the two-week period to have lower levels of
the “figh-or-flight” stress hormone cortisol.
But remember that many chocolate brands
are high in sugar, calories and unhealthy saturated fats, so buyer beware.
First, be sure that the chocolate you're eating is dark chocolate. There is also a big
difference in chocolates’ health effects, depending on how much you eat. As mentioned in the
Cleveland Clinic study:
“'...Be
careful about the type of dark chocolate you choose: chewy
caramel-marshmallow-nut-covered dark chocolate is by no means a heart-healthy
food option.'15 Be aware that milk chocolate does not have the same
healthy effect as unadulterated dark chocolate, because milk
often prevents absorption of polyphenols.
It’s also important to remember the
word moderation.
There’s a measured and tested amount of chocolate – 6.7 grams a day (or one small
square of chocolate two or three times a week) – that provides the best health
benefits. While it undoubtedly comes as a pleasant surprise that chocolate is
actually good for you, eating the right amount is crucial if you want it to be
a benefit and not a liability.”
If you’re craving a decadent chocolate
treat but want to avoid the downsides, take a look at this video so you can
make your own organic
chocolate bars. Also, please be aware that many popular and seemingly
artisan-quality chocolate companies are now owned by multinational corporations
who use GMO ingredients, disregard fair trade standards, and otherwise are not
interested in supporting organic and sustainable production methods.
As examples, Cadbury Schweppes bought
Green & Black in 2005, who in turn was bought by Kraft Foods in 2010.
Dagoba was bought by Hershey’s in 2006. You will find this pattern recur quite
often if you peek beneath the “wrapper” of the chocolate industry. So, please
remember to choose carefully, and consider whether the companies you support
are supporting you back.
