> Processed foods are much cheaper per calorie than "healthy" options.
Attractive is a separate topic. Regardless of budget, for many people a chocolate cake will always be the most attractive food, regardless of cost. Doesn't mean we should have people living on chocolate cake diets.
OP said processed foods are cheaper per calorie than healthy, i.e. eating healthy is more expensive and more difficult.
Nothing at all was said about 'processed foods are more tasty, thus eating healthy is more difficulty', so I didn't reply to it.
Then OP provided Doritos as an example. And I countered by showing that the worlds staple foods eaten by billions, non-processed, are much cheaper than eating processed foods like Doritos example OP gave. That's all.
Now as for your point on taste: try eating a nice daal at your local Indian restaurant and tell me you'd rather eat bags of doritos every day for breakfast, lunch or dinner. If you prefer Doritos then I don't know what to tell YOU.
If you are seriously comparing the attractiveness of “legumes” (what legume and recipe is that?) with the attractiveness of Doritos I don’t know what to tell you.
If you cook something that is nearly as attractive as ultra processed foods, the price skyrockets.
