I understand that it's healthier to eat foods that are more natural/made with natural ingredients. I have no issue with that.
My issue is that putting so much food that people eat regularly (especially people on lower incomes) into one category and labelling it all as if it were all equally bad just removes all nuance and can make healthy choices feel unachievable to people who have less money or less time to spend in the kitchen.
Literally, cheap sliced wholemeal bread is a UPF in the same category as cheap white sliced bread. Same category as a bag of Quavers or gummy bears.
Wouldn't it be better to have one or two more categories to reflect the benefits of eating food that is higher in fibre (e.g. wholegrains, not that weird stuff they add to "healthy" processed snacks) and lower in fat and sugar? Or food that has some additives but is made with a higher proportion of whole foods?
