Also try to remember that a TON of marketing depends upon us parting with our money. A lot of these purist brands and youtubes/evangelists are in it for the profit, too.
They know their audience; those of us with the time and mind and budget to worry about it, and a lot of the more obsessive messaging is unnecessary.
Most of us here are aware of UPF's, so the messaging really ought to be aimed to those who are struggling, both financially and intellectually with eating a balanced diet. There are kids who do not know what a real chicken is, or a vegetable. This is where to issues lie, but strangely the marketing seems to only target the already mindful, more affluent amongst us. I wonder why that is?
No one offers a solution because of capitalism. Ocado and waitrose whoppers have options, these companies will procure items of a higher standard for a higher price, and offer us the luxury of choice (notice Lidl, Asda and Tesco rarely supply nitrate free bacon, decent bread even organic meat in many places - trust me!).
The issue really lies at the Heron Foods, Iceland level, where customers are truly stuck for choice, where the budget is compromised severely. This is the section of our population who are eating too much UPF, suffering health consequences, etc. Yet there's no real galvanising force to change it.
Most of us here are just fine. We can make our choices, and I am sure, even with the occasional sausage roll and left over easter egg it won't affect our longevity or general health.
Please try to be aware of this, it can become an obsession, and within some social groups/communities it can lead to competitive eating, self denial and orthorexia.
