If you want any of the healthy benefits of resveratrol found in
grapes, don't lay there on the couch and allow your spouse to feed you
peeled grapes. The resveratrol is in the skin of the grapes. Let them
bruise the grapes for you instead, before they delicately drop them into
your mouth. Okay, the practice isn't probably one seen in America, but
it is a way to point out the fact that resveratrol is abundant mostly in
the skin of grapes.
Resveratrol is found heavily in red
wine, which is the best source of this phytoalexin. The longer the skin
remains on the grapes while it's fermenting, the more resveratrol you
have in the final product. This explains why white wine doesn't contain
as much and grape juice, with no fermentation contains very little.
You
may wonder why the attention to resveratrol, besides another good
excuse for a glass of red wine. It's simple. It is one additional
protection against heart disease, clogged arteries and cancer. It does
occur in other natural products like eucalyptus, lilies and spruce,
their consumption is dubious at best. It also is in edible products such
as mulberries and peanuts but they don't contain as much.
The
scientific community discovered resveratrol when it looked at the
"French Paradox". The French, noted for their consumption of rich fatty
foods, don't have a high incidence of heart disease. Scientists
wondered why and discovered it was their habit of including red wine
with the meals.
Resveratrol is produced by some plants as a
way to protect itself from fungi or other pathogenic organisms or after
an injury. It produces a chemical substance called phtoalexinsare to
ward off damage. This substance is a powerful antioxidant that scavenges
artery-damaging free radicals.
When it was put to the
test against a synthetic antioxidant and vitamin E, resveratrol lead the
scavenging pack as the best defense for your arteries. It not only
stopped the cycle of the formation of plaque and scar tissue on the
artery, it increased the nitric oxide, which relaxes the vessel walls
and increases the blood flow. Scientists discovered that when you eat a
high-cholesterol diet, your nitric oxide is reduced by a third.
People
taking resveratrol supplements reversed the decrease in their main
arteries. It also keeps the blood cells from getting sticky. It inhibits
thrombin and another polyphenol in wine, quercetin inhibited 12-HETE a
different chemical that makes blood cells stick together. When blood
cells stick together, it creates another potential factor for heart
attacks.
But the heart is not the only organ that gets
protection. Many different studies find increasingly optimistic
information on the potential of resveratrol for the fight against
cancer. It has the ability to differentiate between a cancer cell and a
normal cell and protect the normal cells while it fights the cancer
cell. Unlike the chemotherapy offered today, it doesn't damage healthy
cells. It also plays a role in activating certain hormones, enzymes and
genes while turning off those that are not beneficial. In fact, studies
done with yeast shows that it activates the yeast's longevity gene.
When
it was discovered that Resveratrol activated the longevity gene a
number of anti-aging products came on the market to take advantage of
this fact.
Other studies show that it might be beneficial
to the control and prevention of Alzheimer's by controlling the
abnormally high level of beta-amyloid, an abnormal peptide produced in
abundance by Alzheimer's patients, which causes oxidative stress and
eventually kills brain cells. It also might protect stroke and spinal
cord injury victims from more damage from the complications of their
injury or stroke.
While there are other questions about the potential for liver damage, breast cancer and long-term effects, a glass of wine with a meal isn't as damaging as once thought and the healthy benefits of resveratrol may even make you a little healthier.
