I haven't really eaten vegetables other than potatoes for about 5 years now. My garden bed used to be full of collards & kale in winter. Then I found out about oxalates & had to admit that I really didn't enjoy all the green smoothies.

There is definitely something to eating locally grown produce. I use produce stands on the side of the road all the time. Most of it is grown with standard practices but it always tastes better when freshly picked & naturally ripened.

I think anything you can do to increase your resiliency is going to be useful for what's coming.
