You can easily get bread like this. This is the brand of bread I often buy, and you can find it in a lot of/most UK supermarkets. I've only seen fresh GF pasta in one supermarket (Morrisons, I think), but it does exist. Coeliac UK has a list of restaurants/caterers who they've accredited as being able to provide safe gluten free food, if you need to avoid it to a coeliac level (I hope I'm not breaking a rule here? Just trying to recognise that different people have different levels of gluten-avoidance).
