Wine and arteries: what relationship?

Wine and other alcoholic beverages were given the honor because of their medicinal properties. Wine, or more accurately it contains alcohol, has a protective effect against heart disease.

Populations consuming wine would be better protected than others. This protective effect was more pronounced in the elderly or people suffering from metabolic syndrome (abdominal obesity + diabetes + hypertension). Keeping in mind that alcohol consumption has remained subdued.

The protective effects of wine

Alcohol is primarily responsible for this protective effect, and as beer and spirits are equally beneficial. However, wine is a product rich in various components, along with alcohol, and each year we discover new molecules benefactors in wine, particularly red wine. This, indeed, has a positive role in lipid metabolism, has anti-oxidant, vasodilator, decreases platelet aggregation and inflammation are the primary factors of atherosclerosis. Those responsible for these effects are flavonoids, which are also found in chocolate, tea and pepper, polyphenols (in particular procyanidins that are found mostly in the wines of south-west), resveratrol , quercetin and many other components being identified. The revestratol is a natural antibiotic that is found mainly in grape Tannat and Merlot, and lesser amounts in the Pinot Noir and Cabernet Sauvignon.

The real or supposed virtues of the wine did not have much impact on French consumers are witnessing an annual decline in consumption, which stood at 43 liters per capita per year in 2007, a consumption three times lower than the 1960.

Disillusionment with the wine (but not distilled spirits, which, in contrast, are up) accompanied by a debate on the supposed benefits of wine consumption or abstinence. For oncologists, alcohol has more disadvantages than advantages, and its consumption, since the first glass, increases the risk of cancer disease. Whenever possible alcohol in all its forms, must be avoided.

This position is not unanimously, including the world of medicine, where alcohol, in small quantities daily (equivalent to 2 glasses of wine) has incomparable virtues of the cardiovascular system and metabolism due to its anti-oxidant. Wine consumption also protect against the ravages of Alzheimer's disease.

Different effects depending on context

The effects of wine would be different depending on the food environment: a diet rich in omega-6 fatty acids, such as the Eating present further increase the production of free radicals, carcinogens that a diet rich in omega-3. Similarly, among women, a diet rich in vitamin B12 (green vegetables) protect against the potential effects of wine on the risk of breast cancer. The association between smoking + alcohol is particularly harmful for cancer of the throat and esophagus, while the wine itself does not increase the risk. Finally there are many cases where one might think that the wine has a protective role against cancer, as in the case of prostate cancer.

The ideal is to consume wine in small quantities, during meals, especially during a Mediterranean diet rich in vegetables and omega-3.
