I am sure you are quite correct in everything you say. Pretty sad too when a cooking appliance adversely affects one's eating habits. I can't recall ever buying frozen chips in my life except in the past two weeks I have bought two large packs.
Your post reminds me to use my own potatoes and just roast them in the airfryer. I think they'd taste better than the frozen chips which are convenient, but they have an odd taste to my tastebuds.
