Lmao, my grandma and my mom also used salt, sugar, and fat to “hook us”. The local bakeries and delicatessens have been doing it for centuries. If you want to blame someone, blame the irresponsible consumers, not the producers making perfectly legal products which are completely non-harmful if used appropriately. Otherwise, by equating salt, sugar, and fat to addictive drugs, you are ultimately calling God the biggest drug pusher of all, since we can’t live without consuming those substances He invented.
Your grandma made processed foods for mass consumption? Who would’ve known...
