oof, it's a rough journey. i also have had to put my foot down and eliminate PUFA oils (the machine oils they use in so much food and especially snack production, and most restaurants) and lower my carb intake - and eliminating fructose.

idk what your issues are exactly but seed oils and fructose are the worst. in some cases the cooking method makes a big difference, deep frying potatoes, for example, produces toxic acrylamides, pretty much everything in the snack section is this, if it's not also laced with - oh yeah, not to forget, some more baddies to watch out for is modified starches like maltodextrin. that one causes me huge probems with dental nerves and neuromuscular stuff, is part of how my vision so rapidly declined in the last few years. plus, obviously, stay the fuck away from artificial sweeteners, they are all toxic to the kidneys.

most of the food in this category in supermarkets is literally the reason for all the cancer and diabetes.
