I have received conflicting information in the literature. I have read that white
refined sugar promotes tumor growth, while unrefined sugars, e.g. fructose, maple syrup, agave nectar, etc., do not, and are therefore safe to consume. Conversely, I also have read that unrefined sugars do promote tumor growth because they raise the body's insulin levels, which in turn promotes estrogen production. Is there any conclusive science that the medical community is aware of, on any of this?
