Canned and frozen vegetables are also non-perishable. While some extremely poor people lack a working freezer or storage space, most consumers can easily use these options.
Canned food such as canned tomatoes or canned pickles (if pickled with vinegar/salt/spices) is not considered ultra-processed food. It's considered processed food and can be considered as part of a healthy diet. Well, same could be said about UPF -- your health is unlikely to detoriate long term if you have 1 frozen meal per week. It's just quantity that matters and lack of moderation.
Absolutely nothing I've seen anywhere justifies the idea that access to food is the problem. In most cultures, you don't need cooking classes because the food is ingrained into their culture, and recipes are passed down. Americans have a much weaker link to their heritage. You might know a few dishes, but in my experience, absolutely nobody knows how to cook.
By cook, I don't mean "can add one box of prepared goods to another box of prepared goods with a can of prepared goods on the side", I mean buying meat, veggies, fruit, and grains and cooking a dish from home, mostly from scratch.
edit: 13 million Americans are in food deserts. If the problem were that small, it'd be similar in size to people who are addicted to substances other than alcohol. This is affecting almost everyone. There MUST be another, bigger solution.
It's an observation, not a suggestion. That's literally how many low-income (not impoverished) people live in rural areas. They grow (and hunt) some food at home but not enough to be self-sufficient, and also have a regular job. Sometimes those jobs involve working long hours at peak times. This is a pretty normal lifestyle.
