You might not be able to pass off the daily glass of red-wine as good for your heart anymore.
After years of believing the "The French Paradox," — the high cholesterol diet but low heart disease phenomenon in the French that was attributed to red wine intake, a study released at John's Hopkins University in Baltimore today showed no correlation between red wine and the incidence of heart disease, cancer and inflammation.

The study looked at 783 men and women over 65 years of age in two Italian villages in the Chianti region between 1998 and 2009. Resveratrol, the antioxidant in red wine, chocolate and grapes thought to be the main reason for the beneficial effect of wine, was measured in the urine over 24 hours.
Levels of this antioxidant were measured at three year, six year and nine year follow-ups and multiple markers of heart disease and cancer were documented including:
- Coronary artery disease.
- Cholesterol.
- Blood pressure.
- Mortality.
A total of 268 participants who previously had no heart disease at the start of the study died (34.3 per cent), while 34 (4.6 per cent) developed cancer..
Previous evidence has been conflicted, with some studies showing that the phenols in red wine and chocolate were correlated with decreased cholesterol, blood pressure and diabetes and others showing no benefit or a negative impact.
'People desperately want to believe red wine is good for you. But wanting something to be true doesn't make it so.'- Dr. Chi-Ming Chow
In popular culture, the positive results have received more attention and have led to a $30 million US resveratrol supplementation business in the U.S., the researchers said.
Current recommendations from the World Health Organization, American Heart Association and Heart and Stroke Foundation in Canada is no consumption of alcohol. However, if alcohol must be consumed, the maximum amount should be four drinks a week for women (spread out, not all at once) and seven drinks for men.
There is a relationship in some studies that suggests a modest benefit for a moderate amount of alcohol, but that heart disease tends to increase after that.
Dr. Chi-Ming Chow, a cardiologist at St. Michael's Hospital in Toronto and spokesperson for Heart and Stroke Foundation says this study proves what they've suspected all along.
"People desperately want to believe red wine is good for you. But wanting something to be true doesn't make it so," he says.
The World Health Organization released a report today on the worldwide negative impacts of alcohol, saying that every 10 seconds, someone is killed by alcohol.
"The rumour about wine being good started about 20 years ago with the French," says Chow. "But all the heart organizations will tell you they would prefer you not to drink and take the chance of overdoing it."
He says if you have to drink alcohol, red wine contains grapes and flavonoids that other alcoholic beverages don't, so it's probably the best for you.
As for the French Paradox, the jury is still out on what causes it. But it probably isn't the wine.
