Red Wine And Its Disadvantages.

The benefits of red wine appear to be linked to the presence of resveratrol, melatonin and flavonoids.
Flavonoids are thought to help protect the body from cancer because of their antioxidant properties. They help the body neutralize certain free radicals that can trigger the cellular activity that may lead to cancer.
Melatonin — a substance present in red wine and some foods and that humans naturally produce in small amounts — is thought to delay the oxidative damage and inflammatory processes typical of old age.
Resveratrol is produced naturally by grape skins during red wine's fermentation process. Several studies have suggested that resveratrol may explain the "French paradox" — why the French appear to be able to consume a diet higher in fat than the norm while enjoying a comparatively lower incidence of heart disease.
Red wine has been credited with more than keeping your heart healthy and delaying the aging process. It has also shown promising results in preventing prostate cancer, diabetes, Alzheimer's disease, leukemia and some common food-borne illnesses.A woman tastes one of southern Italy's full-bodied red wines, near Guagnano, in Puglia, the heel of boot-shaped Italy. Red wine has been touted as beneficial to cardiovascular health, but new research suggests that drinking more than a certain amount of that favourite Merlot or Shiraz may actually be harmful over time.

Not all effects are positive
But the long list of potential health benefits does not necessarily mean red wine should be a staple in every household.
Wine is an alcoholic beverage, and pregnant women — or women contemplating having a baby — should avoid alcohol. It can be dangerous to the fetus.
Alcohol can also increase a woman's risk of developing breast cancer. Two drinks a day can increase a healthy woman's risk by 10 per cent — or more if there is a family history of the disease.
Red wine can also trigger migraines in people who are susceptible to them, probably because of the accumulation of histamines and tannins from prolonged contact with the skin of the grape during the fermentation process.
Wine can also elevate your triglyceride levels. High triglyceride levels are associated with health problems such as diabetes.
Drinking wine — or any other alcoholic beverage — can also lead to weight gain. A glass of wine contains about 120 calories and no nutrients — that is, empty calories. Get together with friends, have a few glasses of wine along with a small plate of hors d'oeuvres, and you're approaching your total recommended caloric intake for the entire day. If you're not active, before long, your waistline will be in expansion mode.
