The French Paradox
|There is a strong link between consumption of saturated fat and mortality by myocardial infarction. But in France, the incidence of the disease is a third, even a quarter of that in northern Europe and the USA.|

In the late 1980s two researchers, Jacques-Lucien Richard and Pierre Ducimetière, sought to understand what has become known as the French Paradox, which was revealed to the entire world by the WHO in 1991 after years of research.
Working from the observation that France has the highest alcohol consumption of any country, studies established a link between these data.

This link, which has been verified on several occasions, is called the U graph. On average, in the populations studied, moderate consumption of alcohol reduced the risk of coronary heart disease and high consumption increased the risk, as did no consumption.

Risk of mortality by cardio-vascular disease
One of the main factors is High Density Lipoprotein (HDL) cholesterol, or "good cholesterol", (LDL is the "bad cholesterol"); its level rises in line with alcohol consumption (particularly HDL2, which acts on the artery walls, unlike HDL3 which has no particular effect).
|Total HDL||HDL 2||HDL 3|
|No wine||43.4 mg/l||5.7||37.7|
|75 cl of wine/day||49.4 (+ 14%)||10.4 (+ 82%)||39.0|

We do not all react in the same way to HDL cholesterol. Men respond better than women, obese people less well than others, and the picture is made yet more complex by genetics, especially the polymorphism of the protein CETP (Cholesterol Ester Transfer Protein), which helps HDL's transformation into triglycerides. If wine modulates how the CETP gene is expressed, then new there are fresh prospects in the struggle to prevent genetic diseases.
These vinous benefits are only obtained by moderate daily consumption, suited to the morphology of the person in question.
