While there may be chemical compounds in some varieties of wine that are known to be beneficial, fact is that alcohol is a toxic poison and is definitely not good for the heart, even in small doses. Alcohol free wine would be good for health in general, but who would drink it (not me for sure, I like my poison full strength)

"It's not just the red wine the French love to quaff"

There are many other ingredients that could explain their low rates of heart troubles. For instance, the French:

are the fifth highest consumers of fish and seafood in the world, which adds a huge boost of omega-3s to their intake. These special fats steady the heart's beating, minimise the risk of arrhythmia and keep our tiny blood vessels supple and 'elastic'. Think of those classic French seafood recipes such as coquilles St Jacques, oysters, bouillabaisse, sole meuniere, garlic prawns in butter.

love garlic and add it in generous quantities to just about everything. Forget the Med Diet. The French are masters at garlic consumption, which has been under study for years for its cholesterol-lowering effect.

shun Western-style fast foods such as burgers and fries with their 'bad' trans fat and over-processing.

rarely snack but prefer to dine properly on three main meals without anything in between. Vegetables and salad are always part of their meals.

eat small portions of most things, even though their cuisine is rich and high in fat.

walk everywhere.

P.S. I believe olive oil may also be a key factor

It looks like rain, father.

Any particular type of red wine, Shiraz, maybe?
