You're spreading misinformation/FUD. At a minimum, Ultra Processed Food means it contains ingredients that are added because they "have" to to get it to your mouth, not because anyone wants you to put those ingredients in your body.
I agree that UPF is not rigorously defined yet, but to claim it is "so broad as to cover everything from kimchi to Snickers" is absurd. If it's literally just kimchi, it's not processed. If it's kimchi that has a shelf-stable additive, and a dye to make it look pleasing, and chemicals to hide the taste of the machines that made it, then it's processed.
If your FUD stems from your own ignorance about the subject matter, that's a you problem, quit flaunting it around. If it stems from being a hired shill of General Mills, et al., then I hope you're getting paid well.
