> I'm not arguing that we don't eat more ultra-processed foods. We do eat too many highly refined foods with little nutritional value. My argument is against blaming food additives, dyes, GMOs, HFCS, etc... Eating more whole foods, vegetables, and fruits would make you healthier, but that's due to the nutritional value, fiber, feeling more full for longer leading to reduced caloric intake, etc... Not because you got rid of food dyes.
But the prevalence of the above ingredients serves to increase consumption of processed foods relative to whole foods, both by increasing “addictiveness” aka how much people eat, and by decreasing its cost. HFCS is the best example of this, having heightened addictive properties via increased satiety suppression and dopamine response compared to other sugars, while being heavily subsidized to the point that final prices see a 15% reduction. As a result, HFCS is added to many products it has no business being in, because it increases sales (and so consumption, of processed foods).
