I was also reading an article about nutritional quality of food itself has been declining over the last 50 years. So to get the same nutritional amount, you need to eat more food period.

There’s also bigger systemic issues about food access that is driving people to “choose” it. Lack of time, cost, availability, transportation all factor in that are beyond a simple idea if a person having a pure choice between two equal (or even somewhat equal) options.
