Since the 80's I've been reading labels when I buy my groceries. Things have got so bad now, that it takes me an extra half hour in the store just reading labels. I buy about half my food at the natural health food store, where things are organic and non-gmo & the rest at the supermarket. I too had to give up gluten products because I could no longer tolerate it & became quite ill from it.
This has added much more time to my reading labels....I discovered that gluten is in everything & not always on the labels in my country. I would be quite happy now if I could just take a pill for my daily nutrition, & not have to do the food thing.
