Health benefits of red wine

Updated on June 20, 2013

The effects of red wine on health has attracted a lot of research effort in last decade because of its high concentration of antioxidants, especially resveratrol. It is found that the effects of red wine include protecting people against cardiovascular diseases, some cancers, gum diseases, and others.

Some studies suggest antioxidants in red wine called polyphenols help protect the lining of blood vessels in your heart. These antioxidants come in two main forms: flavonoids and nonflavonoids. Flavonoidsare found in a variety of foods, but red wine has higher levels. Nonflavonoids are found in red wine, which have recently been of particular interest because they appear to help prevent arteries from becoming clogged with fatty blockages. Resveratrol is a member of nonflavonoid that is abundant in red wine and researchers are most interested in. Resveratrol is a group of compounds plants use to defend themselves against attacks such as untimely stress, possible injuries, or UV irradiation and certain diseases such as fungus and infection. It has been shown to have a number of potentially beneficial properties, including antioxidant, anticoagulant, anti-inflammatory and anti-cancer effects. Most of the effects of red wine on skin and health, as discussed below, are attributable to this powerful antioxidant.

1. Red wine helps prevent the possibility of various neuro-degenerative illnesses such as Parkinson's disease and Alzheimer's disease and suspend the progression and possibility of dementia.

2. Red wine is good for cardiovascular system. Tannins and flavoniods in red wines can raise the levels of high-density lipoproteins (HDL) and reduce low-density lipoproteins (LDL) in the blood. Red wine can serve as blood thinners for people with high blood pressure, and it also appears to inhibit platelet aggregation, helping to prevent the formation of clots in blood vessels. Thus it can prevent development of various cardiovascular diseases, heart attacks, as well as strokes. It was reported that French people have lower incidence of coronary heart disease because of their high red wine consumption even though their diet is high in saturated fat. Apparently, it can alleviate ill effect of fatty foods. A double-blind, cross-over study, reported in the September issue of the American Journal of Hypertension (vol 18, issue 9, pp1161-7), also showed that after consuming either 250ml of regular or dealcoholized red wine, patients saw a significant decrease in central systolic blood pressure, the top reading of the blood pressure. Central systolic blood pressure fell 7.4 mm Hg and 5.4 mm Hg after consumption of red wine and non-alcoholic red wine, respectively. Some researchers have attributed this cardioprotective quality to the significant amounts of resveratrol naturally present in grape skin.

3. Red wine can prevent certain cancers. Experts believe that regular and moderate consumption can help fight possible cancer cells from proliferating. The FDA has suggested that one to two glasses of red wine might help reduce one's cholesterol and decrease the chances of cancer. Studies have even shown that alcohol might benefit many bodily organs, including the heart and the brain. At the 71st Annual Scientific Meeting of the American College of Gastroenterology in Las Vegas in 2006, researchers reported that drinking more than three glasses of red wine a week could cut the risk of colorectal cancer by almost 70 per cent,.

4. Red wine can cure and prevent various gum diseases. The polyphenols in red wine can reduce the presence of free radicals that causes the infection and bacteria proliferation inside the mouth.

5. Red wine helps reduce the harmful effects of food poisoning. Red wine can help the body get rid of toxins and prevent dysentery and diarrhea.

6. Red wine can provide healthy skin. Thousands of polyphenol can prevent the damages brought by cell oxidation process and results to healthy and young looking skin.

Red wine has many wonderful effects on our health if consumed moderately.

      You've done your homework! I'm going to link my hub to this one. I recommend visiting and have a look at The Wine Diet by R Corder if you haven't already.
