Because it’s working for me! I want to keep all the estrogen I can out of my body…evista works to help bone density and at the same time keeps estrogen at bay!

An endocrinologist, and now this breast cancer surgeon, are adamant about the sugar/insulin/estrogen connection. My biochemistry background is non-existent but I've also seen studies on Google Scholar linking breast cancer and sugar or high-glycemic index diets, though some is theoretical.

I assumed it was the usual 'overweight' causes higher cancer risk yaddayadda stuff but one oncologist described fat as 'an estrogen machine.' I don't know if that's even precisely true and might depend upon other non-sugary foods in the diet causing the fat storage. But the endocrinologist I saw specifically cited sugar and it's effect on insulin production as triggering increases in estrogen. Any resulting fat storage just adds another estrogen-production issue.

I half-dismissed it sugar is currently under attack in general for just about every health evil and I suspect that excess weight caused by a diet of fried foods would likely also be estrogenic. But I've read more about the insulin and estrogen connection and am persuaded that sugar should be a no-go for me at least.
