There has been a lot of attention given to resveratrol and its promising health benefits in recent times and after well 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 protective enzyme made by some plants when they are threatened by infection from a fungus or bacteria. It is anti-microbial, a substance which helps 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, it is the trans type that shows such promise as a health supplement.
Our natural resveratrol sources are varied, it is found in the skins of red wine grapes and the wine made from them, it can also be found in peanuts, blueberries and a variety of other foods. Its presence in red 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 some cultures to consume diets high in fat without suffering the ill effects.
Experiments on laboratory animals have shown several health benefits. In some well documented experiments mice given a high fat diet and also resveratrol had a much reduced risk of death compared to those given the high fat diet without supplementation.
Those mice were found to have approximately normal levels of insulin and blood glucose though their cholesterol levels were high. Interestingly the anti-aging effects seen in mice appear to have been most evident in elderly 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, other tests to that point 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 attacks other cancers like oesophageal and breast cancer.
A challenge for scientists will be in working out how to get 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 promising looking delivery method is taking resveratrol in such way as allows it to be absorbed from the mouth directly into the bloodstream. Various methods of delivery are now under investigation from mouthwashes to lozenges and even gum.
