This article points at the wines with the highest health benefits. It also discusses in which wines to find specific chemical compounds such as polyphenolsresveratrolprocyanidins and OPCs. The French paradox The French paradox refers to the observation that the French suffer a relatively low incidence of coronary heart disease, despite having a diet relatively rich in saturated fats.

The phenomenon was first noted by Irish physician Samuel Black in Oxidative stress Oxidative stress is an attack on cells when a biological system cannot readily detoxify the redox reactive intermediates or easily repair the resulting damage.

Oxidative stress is involved in many diseases, such as atherosclerosis, Parkinson's disease, heart failure, myocardial infarction, Alzheimer's disease, fragile X syndrome and chronic fatigue syndrome, but short-term oxidative stress may also be important in prevention of aging by induction of a process named mitohormesis.

Free radical scavengers Antioxidants are free radical scavengers: Oxidation is a chemical reaction that Antioxidants research papers electrons from a substance to an oxidizing agent.

Oxidation reactions can produce free radicals, which start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions by being oxidized themselves. As a result, antioxidants often are reducing agents such as thiols or polyphenols.

Polyphenols Polyphenols are a group of chemical substances found in plants. Flavonoids are the most abundant polyphenols in the diet. Tannins of the wine contain some flavonoid polyphenols. It is in the first years of the wine that some polyphenols help prevent cardiovascular diseases and some cancers, among other health benefits.

Other sources of flavonoids include all citrus fruits, berries, ginkgo biloba, onions, parsley, pulses, tea especially white and green teaseabuckthorn, and chocolate with a cocoa content of 70 percent or greater.

Resveratrol in red wines are antibiotics produced by plants when under attack by pathogens such as bacteria or fungi.

Resveratrol is a phytoalexin produced naturally by several plants — including vines. The health benefits of resveratrol on humans are unproven. In mouse and rat experiments, anti-canceranti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects of resveratrol have been reported.

Most of these results have yet to be replicated in humans. Resveratrol is found in the skin of red grapes. Malbec has a thick skin and contains much resveratrol. Vine grapes grown in cooler climates have higher resveratrol levels than those from warmer climes such as California and Spain.

The varieties with most resveratrol in the wine include malbecpetite sirah, st.

Health benefits of procyanidin flavonoids Proanthocyanidins are essentially polymer chains of flavonoids such as catechins. They are also known as OPCspycnogenol, leukocyanidin and leucoanthocyanin.

They are found in many plants, and grape seeds and skin. The effects of proanthocyanidins include neutralizing oxidants and free radicalsdepressing blood fat, and inhibiting destruction of collagen, the most abundant protein in the body.

These influences, along with other mechanisms, explain their benefit in venous and capillary disorders, including venous insufficiency, capillary fragility, diabetic retinopathy and macular degeneration.

Some research indicates that the vascular benefits of red wine drinking depend on the presence of oligomeric proanthocyanidins. Additionally, studies have shown that OPCs may prevent cardiovascular disease by mitigating the negative effects of high cholesterol on the heart and blood vessels.

These procyanidins are the most abundant flavonoid polyphenols in red wine — up to one gram per litre is found in some traditional style red wines. Repartition is discussed below.
