Sugar from what I understand spikes your blood sugar. My main reason not to consume it is because I am trying to avoid dementia, which seems to run in my family. I think sugar overall is bad for us. I read the book Sugar Crush years ago and I forget the specifics now. I just decided not to consume it if I can avoid it. I do have maple syrup from time to time because it is lower on the glycemic index, so it doesn't give the spike. I do have some sorbet from time to time. So, I don’t totally deprivd myself. I have such a restricted diet because I am gluten and dairy free. I don’t think brown sugar is any better than white sugar, but you just need to find a balance if you really want your treat. I have read if you take a walk after consuming food helps. Pair it with fiber, fat, or protein I have read, helps slow down dugestion. Try reading the book, Sugar Crush, or research online. Best wishes.
