Wine May Have
Health Benefits of Red
of white wine can take heart. Israeli scientists have devised
a way to make white wine that boasts health benefits similar to
those of red wine, which is believed to help ward off heart disease.
published in the Journal of Agricultural and Food Chemistry details
a process that yields white wine rich in disease-fighting antioxidants,
much like red wine already is.
traditionally is made without the use of grape skins, while red
wine is made by fermenting the juice from grapes along with the
skins. Grape skin provides red wine with its color, and it also
contains the highest concentration of polyphenols, which are potent
led by biochemist Michael Aviram of the Rambam Medical Center
in Haifa, Israel, developed a method to make white wine using
that oxidized cholesterol in the blood is deposited in the arteries
and can cause blockages and heart attacks. Consuming antioxidants
can help prevent this process.
to prevent this oxidation of cholesterol, we need to consume antioxidants,
preferably natural antioxidants that you get from fruits and vegetables,''
he said in an interview.
what nutritionists call the ``French paradox.''
in southern France, even though they eat fatty food, they get
almost one fifth the rate of heart attacks as, let's say, the
Finnish people who also eat fatty food. Studies demonstrated that
it has to do with the consumption of red wine in southern France,''
researchers argue that the link between wine consumption and reduced
risk of heart disease remains unproven in the absence of long-term
human clinical trials. THERE'S MORE THAN ONE WAY TO SKIN A GRAPE
including me, like white wine. So I said, 'How can I prepare white
wine...with this beneficial health effect on cardiovascular diseases?'''
he could increase antioxidants in white wine by extracting more
grape skin polyphenols during processing.
team used whole squeezed grapes and incubated them for up to 18
hours in the presence of alcohol before removing the skins. This
increased white wine polyphenols up to six times the normal level,
and the revved-up wine showed antioxidant activity similar to
that of red wine.
content of the white wine was still just one quarter of the amount
in red wine. But Aviram said the similar antioxidant activity
between the two wines suggests that white wine contains varieties
of polyphenols with higher antioxidant activity than those found
in the red wine.
also one interesting side effect of the process: the wine had
the same color and aroma of regular white wine. But the addition
of alcohol to the fermentation process produced an increase in
the sugar level of the wine, yielding a sweet, dessert-type white
``I like this
dessert white wine,'' Aviram said, ``but I'd like to get dry white
wine which also will have a red wine-like health property.''
At least one
wine manufacturer in Israel has begun making the white wine using
the technique developed by Aviram's laboratory. He said he expects
the new white wine to be sold in the United States by the end
of the year.
