I would check out that link to make sure there is some hard science to back it up, because cancer does like estrogen and a large load of
blood glucose does cause a temporary insulin surge. I would guess unrefined
sugar and most carbohydrate foods probably cause a bit less of a glucose load in the bloodstream and therefore less of an insulin surge than refined sugar products, and my guess is that there should be a lot of information out there in the diabetes literature.
