I'm not going to read through all six pages right now, but in many poor areas, especially in large cities in the U.S., there are no nearby grocery stores that sell fresh produce, just convenience stores and fast food outlets, and only poor public transit options.

Furthermore, many school districts cut out home economics classes (cooking and sewing) for being "expensive frills" decades ago, so younger poor people may never have had any training in how to cook from scratch.

I once belonged to a food co-op that was located near both affluent and poor neighborhoods, and one of the excellent services it provided was free classes in how to cook from scratch on a low budget. But such efforts are all too rare.
