I do not know where you speak from but basic fresh ingredients are cheaper per mass unit where I live than processed foods and these are also taxed higher than basic food items because of being deemed unnecessary for a balanced diet.

Cooking also does not take very much time and it is easier today to have access to cooking aids that almost cook by themselves or require minimum atention.

And where in particular have I shamed anyone for eating junk food? What I stated is that junk food should not be considered an option for a diet, even less when trying to move people away from meat consumption, which is also considered a bad dietary option both by health and ethical reasons.
