There seems to be confusion over what products make a food an UPF. I gave the example up the thread that any manufactured product (the example was oat milk) with the ingredient list including rapeseed oil, includes UPFs as the production of rapeseed oil for food manufacturing, subjects the rapeseed to a range of processes including bleaching that puts it in that category.
Food has been divided into categories according to the extent of processing. They are called the Nova categories and are as follows:
1) Unprocessed and minimally processed foods;
2) Processed culinary ingredients;
3) Processed foods
4) Ultra-processed foods.

watermeadow I am sorry but your confidence in the diet of older people is unwarranted. Products like salad cream, tomato sauce, brown sauce, mayonnaise, mustard all include UPFs. It isn't just cheap ready meals.
I have randomly pulled 4 items from my larder. Cream of tomato soup, baked beans, horse radish sauce and a tin of ratatouille, which I thought contained nothing but vegetables, but all include UPFs as follows
_tin of cream of tomato soup_: rapeseed oil, modified maize starch, acidity regulator, citric acid, basil extract, flavourings
tin of baked beans modified maize starch, flavouring
horseradish sauce rapeseed oil (main ingredient), modified maize starch, stabiliser (Xanthan gum)
tin of ratatouille modified maize flour, acid regulator, citric acid.
It is the build up of UPFs in all sorts of foods we might think as 'safe' and eat without worry that is the cause of the problem. All supermarket bread contains UPFs.
