I think many would be surprised what is UPF. One hell of a lot of food and drink.
Colman's mustard in the little jar? UPF.
Salt and vinegar crisps? UPF.
Hovis sliced loaf? UPF.
Wraps (except Crosta and mollica to the best of my knowledge)? UPF
Fajitas seasoning mix, ice cream (except good quality vanilla), ice lollies, ready popped popcorn, baked beans (except organic), most cereals, a lot of jams (not Bonne Maman), most chocolate, most sweets, most frozen or refrigerated items like burgers, pizzas, sausages, yogurts, cheese spread, chocolate spread, some peanut butters, jelly, Philadelphia (buy own brand), flavoured coffees, hot chocolate powder, cocoa powder, cakes, biscuits, bakery items, doughnuts (bastards), tinned soup, fizzy drinks, most crisps unless just salted, milkshakes, fruit squash, gin, vodka, whisky, rum, and most spirits. It's a bloody mine field. If you read the ingredients and there's a long list or there's ingredients you can't pronounce or most people wouldn't have in their cupboards then it's likely to be UPF.
