Red Wines Could Be Dangerous - forwardone - 10-30-2008 11:33 AM
Wines from 13 different countries contain potentially hazardous levels of metals, according to a chemical analysis by British scientists.
The findings suggest that the health benefits of drinking red wine may often be counter-balanced by risks posed by excessive levels of metals such as copper, manganese and vanadium, researchers at Kingston University said.
Wines whould also be labelled with their ion metal content, and manufacturers need to introduce new methods to remove the potentially hazardous material from their products, they said. Metal ions are charged atoms, which play an important role in body biochemistry but which can also be hazardous in excess amounts.
The study, by Professor Declan Naughton and Andrea Petróczi, used a system of risk assessment known as target hazard quotients (THQ), developed by the US Environmental Protection Agency, to examine the risks from metal ions in wine.
The THQ gives an indication of risk based on published upper safe limits for chemicals, and probable levels of consumption and body weight. A value of one is considered safe, though higher scores may also pose no risk because the system is designed to avoid underestimating hazards.
Only wines from Italy, Argentina and Brazil did not exceed the threshold risk THQ of one, the scientists reported. Wines from other countries, including popular producers such as France, Germany, Austria and Portugal, regularly exceeded this.
Typical THQ values ranged from 30 to 80, while Huungarian and Slovakian wines reached as high as 300. Both red and white wines scored poorly in the survey. Details of the research are published in Chemistry Central Journal.
“These values are concerning, in that they are mainly above the THQ value of 1.0,” Professor Naughton said. “Excess intake of metal ions is credited with pathological events such as Parkinson’s disease.

I drink red wine every day and have been for MANY years.
Most of the red wine I've been drinking for the last 14 of those years is locally produced in a mountainous region, the vines are not sprayed with chemicals and the water supply is natural.
We musn't forget that fish is claimed to be good for us, with omega 3 etc., but it also contains mercury, no matter where it's caught in the world and that ain't good for anyone.

Who knows what to believe anymore?
Doctors generally suggest that during pregnancy NO alcohol should be consumed.
Now, on this morning`s news, I saw that a recent study shows that in moderation, a couple of glasses a week, children of those who do have that amount progress as well, if not actually better, than those who`s mothers abstained.

Hey Forwardone,
As far as i know a glass a day is good for you. Red wine is a particularly rich source of antioxidants flavonoid phenolics, so many studies to uncover a cause for red wine's effects have focused on its phenolic constituents, particularly resveratrol and the flavonoids. Resveratrol, found in grape skins and seeds, increases HDL cholesterol and prevent blood clotting. Flavonoids, on the other hand, exhibit antioxidant properties helping prevent blood clots and plaques formation in arteries. Drinking in moderation is good rule.
