Check out "Additive Alert" and "Failsafe" - both have websites and books.

Do we just stop buying canned/ packaged foods and go for the organic stuff instead? I buy stuff with no "bad" additives - there is a lot out there you just have to read labels. I also cook a lot from scratch

What about things like cheese, milk, bread, pasta, etc. How/ where can we get the healthy versions of these? Bread from Bakers Delight, cheese with no colours added, normal pasta and milk

What about costs? We're pretty limited on funds at the moment can we get this cheaply or is it going to cost us the earth? I have found it cheaper

What about healthy alternatives to take away, I know we can make our own pizza but what else? We make hamburgers, pizza, "subway" nuggets and chips
