Should red wine be consumed to prevent cardiovascular illness?

The “French paradox” – the property attributed to red wine of decreasing the risk of coronary thrombosis – is observed for all alcoholic drinks. It has been observed for consumption of approximately 1 to 1 ½ glasses* per day (between 10 and 20g of alcohol). Beyond that level, the benefits are outweighed by the bad effects. These beneficial effects are observed only when consumption is regular and daily; it should not be consumed all at once at the weekend.
 
*The standard glass of wine = 10 cl = 10 g of alcohol
