Welcome
to the wonderful world of Chocolate
Heart-Health
Benefits of Chocolate
But did you know that chocolate
could result in health benefits? Researchers have
discovered that chocolate has specific heart-health
benefits. This is good news for chocolate lovers.
What are flavonoids? Flavonoids
are naturally-occurring compounds found in plant-based
foods recognized as exuding certain health benefits.
Flavonoids are found in a wide array of foods
and beverages, such as cranberries, apples, peanuts,
chocolate, onions, tea and red wine. There are
more than 4,000 flavonoid compounds; flavonoids
are a subgroup of a large class called polyphenols.
Have you had your flavonoids today? Flavonoids
have become a hot topic in the media and in scientific
journals.
Flavonoids provide important
protective benefits to plants, such as in repairing
damage and shielding from environmental toxins.
When we consume plant-based foods rich in flavonoids,
it appears that we also benefit from this “antioxidant”
power. Antioxidants are believed to help the body’s
cells resist damage caused by free radicals, formed
by normal bodily processes such as breathing or
environmental contaminants like cigarette smoke.
When the body lacks adequate levels of antioxidants,
free radical damage ensues, leading to increases
in LDL-cholesterol oxidation and plaque formation
on arterial walls. In addition to their antioxidant
capabilities, flavonoids also:
- Are thought to help
reduce platelet activation
- May affect the relaxation
capabilities of blood vessels
- May positively affect
the balance of certain hormone-like compounds
called eicosanoids, which are thought to play
a role in cardiovascular health
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. Next, 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.
More research needs to
be done to determine how much chocolate we can
eat in order to acquire cardio-protective benefits.
Until then, enjoy chocolate in moderate portions
of a few times per week. Don’t forget to
eat other flavonoid-rich foods like apples, red
wine, tea, onions and cranberries. As soon as
more research has been done, it will be posted
on this website. |
