While you can buy baked beans that are nothing but salt, sugar and starch, (plus xanthan gum - I don't know what it is, but it's in everything in Sainsbury's "value" range), you can also buy The King Of Beans. (I shop at Sainsbury's, which is the middle-to-posh supermarket chain in the UK - between Morrison's, Tesco and Asda and Waitrose, so that's what I base things on). Sainsbury's fresh pasta, for example, is very tasty; we had the tortellini with gorgonzola and walnut last night.
Maybe UK consumers are just pickier; but there's a definite trend towards sourcing in-season produce from the UK, that produce being of a decent standard, and organic stuff is a significant minority of product lines. Overpriced, of course, but the aforementioned vast buying power will rectify that once the economies of scale ramp up.
