The problem with Doritos and IMO all other ultra-processed foods is not that they're bad for us, although they certainly are that; it's that they are designed to push all sorts of sensory ‘buttons’ to make it near-impossible to stop. I'm as vulnerable as anyone else. My solution is to keep them out of my environment. Simply not purchasing them keeps them out of my house. Out of a vending machine is not so bad as the serving size is limited to the size of the bag, but I try to opt for something less processed, like popcorn (what I go for at home when I'm feeling snack-deprived). And at home I can put nutritional yeast on it which gets me B vitamins.

As a sidenote, I've noticed that a number of snack ‘foods’ are cooked with cottonseed oil (lookin’ at you Frito-Lay). Cottonseed oil is a byproduct of growing cotton. I'm being Captain Obvious here — but what's not obvious is that cotton is grown as a textile, not a food, so there's a different set of regulations about what can be sprayed on it.
