I think in most of human history, fructose was a rare treat, not very easy to find. We have bred fruits to have a lot more sugar in them than they used to.

Thanks everyone for the welcome. What I meant about low carb and PCOS is that a lot of women with PCOS find that the lower they go with carbs, the better their PCOS symptoms are -- the facial hair, weight issues, as well as ovulation problems. And yeah, I'm sure insulin is related to PCOS, so lowering the carbs would help that, right? Dairy does seem to be a problem for me -- yogurt and cheese give me migraines, and milk gives me gas and postnasal drip. Fun!

I have done a low carb diet, and also a modified paleo diet, and found that definitely carbs do make me gain weight (very rapidly). I have a friend who is doing a raw vegan diet who says that animal protein can also raise insulin, and that a raw vegan diet that is mostly green veggies and low glycemic nuts, seeds and a few fruits like tomatoes is better to control insulin levels and lose weight. I don't know whom to believe. I know that I need lots of protein and I do also eat some green veggies. I do get tired of meat sometimes. Is there any information about the paleo diet and its effects on insulin?
