I don’t have much knowledge of that struggle.
Most of the food we eat comes from the wife’s parents farm.
They raise Black Angus, veggies come from the garden, and are canned, and preserved (what we don’t consume in the summer).
My SIL, and Grandsons are avid hunters, so we have venison, elk, wild boar/pig, etc., in the freezers. They also raise pigs.
We get eggs from a neighbor.
About the only meat we buy from the store is the occasional chicken.
The only thing genetically modified around here is if they breed a Red Angus with a Black. :)
