A very useful wee guide to food additives, with easy-to-understand smiley faces or frowny faces to indicate whether they're going to kill you or not. I wrote an article on food additives a few months back, and found this a brilliant resource. I was also gratified to know that the orange colouring in Cheezels (the NZ version of Cheetos) isn't harmful. Unfortunately, blue Froot-Loops are little rings of death. I'm not sure about the purple ones yet. And MSG? Don't even get me started.
