We in America are equal opportunity grape consumers -- we
love our red and our green grapes. But we decided to settle an
age old question once and for all. Which grapes are better f
or
your health, the red ones or the green ones?

Both red and green seedless grapes that we eat as snacks in
America belong to the European species, Vitis vinifera.  Two
grapes that are native to America are Vitis labrusca and Vitis
rotundita.


The red seedless grapes you find in America are therefore
European Vitis vinifera, American Vitis labrusca or a hybrid of
the two.


The same is true of green seedless grapes; they are European
vitis vinifera,  American Vitis labrusca or a hybrid of the two.


The green grapes most popular in America are "Thompson
seedless grapes". These crunchy sweet grapes make up half of
the green table grapes eaten in America.

California is the top producer of red grapes in the nation. Of
the twelve most popular varieties, a type called "Flame seedless
" are the most popular table grape we eat as snacks.

Though both red and green grapes are delicious, our research
of all existing studies on the health benefits of grapes has
picked a clear winner when it comes to your health --choose
red. Here's why:





The Skin of Red Grapes Contain More Antioxidants Than Green
Ones




Red grapes are red because they contain a pigment called
anthocyanins. All red, blue or purple foods are colored by this
pigment and contain the same antioxidants.



Anthocyanins are flavonoids that has been studied extensively
for their ability to lower rates of cancer, heart disease,
osteoporosis and arthritis. We have written about them as the
reason for much of
the power of purple foods to transform
your health
.  Recently, anthocyanins in cherries and blueberries
have even been linked to lower rates of erectile dysfunction
and for their ability to
help prevent obesity.

The antioxidants in red or purple grapes are particularly potent
against dysfunction of your arteries. The inner wall of the
arteries, called the endothelium, is damaged when exposed to
free radical compounds. These compounds are missing an
electron and when they make contact with your artery walls,
they pluck an electron from wherever they can, causing
damage.  This damage over time can raise your risk for
heart
disease
, stroke, diabetes, obesity and other diseases including
Alzheimer's disease and erectile dysfunction.

Adding foods rich in anti-oxidants simply scavenges these free
radicals and therefore protects your endothelium.

Here is an example. Eating too much sugar triggers free radical
formation. Having chronically elevated blood sugar
(hyperglycemia) is a highly oxidized, damaging state studies
have shown.  

But, a 2012 study from the Cardiothoracic and Vascular
Department, University of Pisa; Italy discovered that
components of red grapes block the oxidative damage caused
by elevated blood sugar levels. As the study concluded "Red
grape components are a source of antioxidant compounds that
ameliorate [endothelial progenitor cell]  viability and function,
while preventing endothelial dysfunction ".


Red Grapes Contain Resveratrol Which Lowers Heart Disease
Risk

































Resveratrol may be the answer to a health puzzle doctors have
tried to figure out for decades.  Called the "French paradox",
it's the puzzle of why the French, who eat rich creamy foods,
heavy in saturated fat, yet have lower rates of heart disease
than we do.

The paradox was first studied in detail in 1992 by French
scientists Renaud and de Lorgereil of INSERM, Nutrition and
Vascular Physiopathology Research Unit.  Their study, called
"Wine, alcohol, platelets, and the French paradox for coronary
heart disease " was an examination of other studies, comparing
coronary rates and types of alcohol consumed in  Scotland ad
France. Scotland was known to have high rates of coronary
disease.

These scientists observed that wine accounted for 57% of the
alcoholic drink consumption in France. They then hypothesized
that the red wine may explain the French Paradox because the
wine caused a decrease in platelet aggregation and thus
coronary heart disease.


Platelet aggregation makes your blood sticky and harder to
move through your arteries. Compared to the French, the
scientists noted that the Scots have higher platelet aggregation
probably because they drink less red wine.

It's the red wine, many scientists now believe. The French
drink red wine and cook with red wine. Red wine, from of
course red or purple grapes, is rich in resveratrol, a powerful
anti-oxidant.

Scientists now increasingly believe that drinking red wine
blocks oxidative damage that would otherwise result from
eating a diet rich in cholesterol, cheese and red meats.



The breakthrough analysis by the French scientists triggered a
wave of other research. The World Health Organization in 2009
found that  the ratio of deaths from coronary heart disease in
France is 200% to 300% lower than other countries such as
the US, UK, and Sweden.



In 2002, scientists identified the components in red wine that
are responsible for the string anti-coronary effect.

The study, from the Department of Viticulture and Enology,
University of California observed that a glass of red wine has
200 mg of phenols compared with just 40 mg in a glass of
white wine.  That is 5 times more healthful phenols in red
grapes than green grapes.

The list of these phenols is long. Red wine contains flavonols
such as
myricetin,

kaempferol,

quercetin, in dominant amounts;

the flavan-3-ol monomers catechin and epicatechin,

oligomeric and polymeric flavan-3-ols, or proanthocyanidins,

anthocyanins,

phenolic acids including gallic acid, caftaric acid, caffeic acid,

p-coumaric acid, and

resveratrol in a dominant amount.

Red grapes are the source of all of these healthful phenols
found in red wine.
