Yes, resversatrol really works, protecting the body from carcinogens. You can also find it in red wine, which is better than pills.
If that was true, and I accept there are other factors so lets compare like with like nations, wouldnt muslim countries therefore have a higher incidence of cancer?
It also depends upon the level of carcinogens one is exposed to, there are carcinogens in all kind of unexpected places (granite frinstance is a source of radon gas), but are associated with a first world lifestyle.
And Islamic countries are mainly in the Global South with a lower life expectancy and causes of mortality other than wasting disease are more significant.
Also, male circumcision practised in Islam reduces the risk of at least one form of cancer.
Really Islame, I don't believe there are any Islamic countries that can be directly compared to Kafir countries in all of these things.
