Interesting read, but it does not say HOW MUCH do you need to eat before you see the side effects. It's not like she drinks it by the gallon! I don't really think it would do her harm. If used in moderation (like most things in life - chocolate, ice-cream, excersice) I don't think it would be harmfull, my opinion
BTW I think in the 13 month's of dd's life, she only had about 100ml ish of the stuff. Don't think that is enough to cause bladder problems or cancer
