| Dark Chocolate Is Healthy Chocolate |
Dark Chocolate Has Health Benefits Not Seen in Other Varieties
By Daniel DeNoon
Dark chocolate -- not white chocolate -- lowers high blood pressure, say
Dirk Taubert, MD, PhD, and colleagues at the University of Cologne,
Germany. Their report appears in the Aug. 27 issue of The Journal of the
American Medical Association.
But that's no license to go on a chocolate binge. Eating more dark
chocolate can help lower blood pressure -- if you've reached a certain
age and have mild high blood pressure, say the researchers. But you have
to balance the extra calories by eating less of other things.
Antioxidants in Dark Chocolate
Dark chocolate -- but not milk chocolate or dark chocolate eaten with
milk -- is a potent antioxidant, report Mauro Serafini, PhD, of Italy's
National Institute for Food and Nutrition Research in Rome, and
colleagues. Their report appears in the Aug. 28 issue of Nature.
Antioxidants gobble up free radicals, destructive molecules that are
implicated in heart disease and other ailments.
"Our findings indicate that milk may interfere with the absorption of
antioxidants from chocolate ... and may therefore negate the potential
health benefits that can be derived from eating moderate amounts of dark
chocolate."
Translation: Say "Dark, please," when ordering at the chocolate counter.
Don't even think of washing it down with milk. And if health is your
excuse for eating chocolate, remember the word "moderate" as you nibble.

Quotes from Cleveland Clinic Heart Center
It is not secret that fruits, vegetables and grains convey health
benefits - we've been told that for years. But did you know that
chocolate could result in health benefits, more specifically
heart-health benefits?

Forms of Chocolate
Before you grab a chocolate candy bar or slice of chocolate cake, let's
look at what forms of chocolate would be ideal over others:
When cocoa is processed into your favorite chocolate products, it goes
through several steps to reduce its naturally pungent taste. Flavonoids
(polyphenols) provide this pungent taste. The more chocolate is
processed (such as fermentation, alkalizing, roasting), the more
flavonoids are lost.
To date, dark chocolate appears to retain the highest level of
flavonoids. So your best bet is to choose dark chocolate over milk
chocolate.
Some chocolate manufacturers are studying ways to retain the highest
level of flavonoids while still providing acceptable taste. Stay tuned
for more information in this area.
What about all of the fat in chocolate?
You may be surprised to find out that chocolate isn't as bad as once
perceived. The fat in chocolate, from cocoa butter, is comprised of
equal amounts of oleic acid (a heart-healthy monounsaturated fat also
found in olive oil), stearic and palmitic acids. Stearic and palmitic
acids are forms of saturated fat. Saturated fats are linked to increases
in LDL-cholesterol and risk for heart disease.
Research indicates that stearic acid appears to have a neutral effect on
cholesterol, neither raising nor lowering LDL-cholesterol levels.
Palmitic acid on the other hand, does affect cholesterol levels but only
comprises one-third of the fat calories in chocolate.
This great news does not give us a license to consume as much dark
chocolate as we'd like.
First, be cautious as to the type of dark chocolate you choose: chewy
caramel-marshmallow-nut-covered dark chocolate is by no means a
heart-healthy food option. What wreaks havoc on most chocolate products
is the additional fat and calories added from other ingredients.
Second, there is currently no established serving of chocolate to reap
the touted cardiovascular benefits. However, what we do know is you no
longer need to feel guilty if you enjoy a small piece of dark chocolate
once in awhile. |
