We do.
There's another little cook book called "low to no additives" written by some mums in SA which has some good recipes in it. We try not to buy anything processed, i usually even make our own bread and yoghurt. Although not atm as we are in the middle of packing house. Once you get into the swing of it it is pretty easy. I just tend to just shop at local markets, the greengrocer and butchers. I do have have to go to the supermarket for some things, but not too often.
Farmers markets are good for additive free sauces, breads and cakes i find.
