Freedom Foods Ultra Rice Maple Crunch was recommended for our 3 year-old as part of a dairy free/gluten free diet. Because he's on Autism spectrum he can be quite fussy with food, but he loved it so much, he ate three bowls for lunch (I was so excited, as he's been hard to feed).
It is clearly marked as Gluten-Free, Wheat-Free, Nut-free (great) and also clearly states that it contains nothing artificial. Silly me, I didn't read the label and see that it was Maple FLAVOURED syrup, not the pure stuff. What followed was a total regression in his behaviour: 2 hours of hell. Behaviours that hadn't manifested themselves for the past month suddenly reappeared including, stripping off his clothes (4 times in 30 minutes), drawing on walls, climbing up bookshelves/kitchen benches. Before diet modification this behaviour would have been done separately ( ie we'd have a day or week of stripping off, then maybe a day of drawing on walls, with some climbing thrown in another day) so it was very rare for all these behaviours to appear all together, and in such a short period of time.
Once I realized there was a reaction, I read the box properly (yes, I know I should have done it beforehand), and noticed that it included Butterscotch as an ingredient (under the heading Nature Identical). It's a mistake I won't be making again - Maria by email. (Freedom Foods responded that they are working to replace this flavour with a nature-identical flavour within 6 months, which might be failsafe)
