One of the other benefits of my personal experience of nursing Bear has simply been becoming so aware of what I put in my body. When I had IBS years ago, there was a time that I was lactose intolerant. I only avoided obvious dairy, though, and still ate dairy that was in prepared food in trace amounts. Since we discovered that Bear is sensitive to dairy, soy, corn, wheat & nuts, as well as most seeds, the entire way I eat has changed. I've always tried to eat whole foods, including lots of fruits & vegetables, but now, 95% of my diet is made from scratch. I even started making my own rice milk (though it's not very good!).
I have also become quite the label reader. High-fructose corn syrup is in everything. It's actually quite frightening. Soy is in everything. And why does food have so many fillers in it?
My tastes have changed. I ate peanut butter for the first time in at least 8 months, and it didn't taste that good. It used to be my #1 favorite food! I think I'm going to have to get some of the grind-your-own kind, rather than the roasted-peanuts-ground-up-with-salt-added kind. I also think back to some of my formerly favorite foods & wonder if I'd even like them anymore.
All in all, I wouldn't change anything that I've been through in the past year. I'm thinner than I've ever been naturally (as in not because of IBS/sickness or anorexia), and I feel pretty good. I think I'd feel great if I could get 7-8 hours of straight sleep, but you can't win 'em all :)
