Resveratrol is a polyphenol type flavonoid currently exciting great interest as a potential boon to health and fitness.Like other flavonoids as well as polyphenols, it is a very useful anti-oxidant in its right, but resveratrol has attracted particular attention as a potential solution to the particular so-called “ French Paradox”.
This is the term used to refer to the phenomenon, which has long been a puzzle to clinical science, by which rates of cardiovascular disease in France have remained low relative to those in the rest of the developed world, despite the widespread national consumption of a diet high inside animal fat and cholesterol, and a firmly entrenched tobacco habit.Of course France also enjoys many of the benefits of the so-called Mediterranean sea diet through its large intake of fresh fruit and vegetables, oily fish and olive oil, but there are good reasons to think that the consumption of red wine may as the real explanation of any apparent paradox.
It is known in any case that the moderate consumption of alcohol has a significant protective effects on the cardiovascular system, reducing disease by as much as 20-30%, but conventional medical opinion is characteristically cautious in acknowledging how the resveratrol in red wine might have any benefits over and above those which would in any case be provided by all the alcohol.However, the role of fat-soluble anti-oxidants in protecting the circulatory product from damaging free significant attack is well comprehended, and it would therefore appear how the resveratrol and other polyphenols found in red wine can basically be beneficial.Laboratory tests, moreover, have shown resveratrol to have significant anti-coagulant and anti-inflammatory influences.
For the purposes of obtaining your intake from resveratrol from wine you need to know that it’ s contained principally in the skins of red and / or black grapes, and is consequently found in significant quantities only in those wines made by an initial pulp fermentation that allows the developing alcohol to help leach both colour besides other substances, including resveratrol, from the skins.It follows that the longer this pulp fermentation is allowed to continue the more resveratrol the wine will contain.So the colour of the wine is really a handy guide.Generally, the richer and darker the colour of the wine the more resveratrol will be identified.Rose types and light reds may contain certain, but white wines produced by a juice fermentation alone will provide little if any.
Usually it is the red wines produced in the sunnnier climates close to the Mediterranean, and the New world, which will be most wealthy in resveratrol, and dark red wines of the type may provide as much as 2 mg of resveratrol in a small 5 oz wineglass.But unfortunately from a health point of view, these also tend to become the strongest in alcohol and the so-called “ congeners” which accentuate hangovers.
But fortunately for those who dislike red wine, or are concerned about alcohol intake, other sources of resveratrol are available.The amount in foods varies broadly, but the best origins are peanuts and inflammed grapes, both of which may provide anywhere between 0.3 and 1.3 mg of resveratrol per cup.Bilberries and cranberries may also be a useful source.
Supplements of resveratrol are also now readily available, principally in the form of red wine or pink grape extracts, which will also contain other anti-oxidant polyphenols.Manufacturers’ recommended doses will typically supply between 10 and 50 mg from resveratrol, which would require a very high, and potentially hazardous, level of wine consumption to achieve regularly.
That said, there is no known toxicity from taking resveratrol, as such, although its blood thinning properties will tend to inhibit the blood’ s clotting ability as well as resveratrol is therefore not recommended for those taking anti-coagulant drugs such as warfarin, or certain types of anti-inflammatory including aspirin.Needless to say, however, toxicity problems of a different kind may manifest if alcoholic drinks are used to excess as the principal or only source.
But as noted above, moderate consumption is generally recognised to be good for health, particularly for the cardiovascular system.So the message seems to be:if you want to enjoy a couple of glasses of wine utilizing your dinner then go proper ahead.And have that period old pleasure enhanced by the knowledge that the resveratrol it contains is also doing you some very nice.
