Resveratrol Health Benefits

There has been a lot of attention given to resveratrol and its apparent health benefits in recent years and following widely publicized television coverage, a huge increase in demand for the product but lets take a look at what resveratrol really is and why there is such interest.
Resveratrol is a substance produced by some plants when they are under threat from bacteria or fungus. It is anti-microbial, helping to fight infection by acting as a defender against attacking bacterial or fungal cells. Resveratrol exists in two forms, the cis type and the trans type, the trans type being the one which shows great promise as a health supplement.
There are many different sources of resveratrol, it is found in the red wine grapes and the wine made from them, it can also be found in peanuts, blueberries and a variety of other foods. Its concentration in wine varies a lot with the grape variety and where it was grown. It is thought by some to be the reason for the ‘French Paradox ’, the apparent ability of Mediterranean people to consume seemingly unhealthy diets without all the ill effects.
In animal trials, resveratrol has shown several health benefits. In a famous experiment, mice given a high fat diet and resveratrol supplements had a much reduced risk of death compared to those given the high fat diet without supplementation.
The mice in that experiment had fairly normal levels of blood sugars and insulin though their cholesterol levels were high. Interestingly the anti-aging effects seen in mice appear to have been mainly in older mice rather than in mice given resveratrol supplements from an earlier age.
Life extending properties were also shown when an Italian team of scientists experimenting with fish found that resveratrol could extend their lifespan considerably. This was the first such demonstration in a vertebrate, previous experiments having been on fruit flies and worms.
Resveratrol shows great promise in the fight against some cancers. Experiments on lab mice show success with skin cancers and test tube experiments show resveratrol fights other cancers such as colon and breast cancer.
A challenge for scientists will be in working out a reliable method of getting the right dose of resveratrol actively fighting cancer effectively. This challenge arises because resveratrol needs to be preserved for long enough in the body to reach the bloodstream without being broken down. One possibility is that of taking resveratrol in such way as allows it to be absorbed from the mouth directly into the bloodstream. Various ways of taking resveratrol are being considered from mouthwashes to lozenges and even gum.
