Actually they use natural food dyes- I was surprised and pleased at this when I was considering getting them for my 2-year-old. My favorite crackers are Wheat Thins, I don't buy them because I'll devour a whole box. I picked up a box of Nairns oatcakes and thought they tasted like sawdust. My 2-year old loved them though. I picked up another box, this time of the mixed berry oat biscuits and love them.
