I have Coeliac's and things with gluten are out for me unless I want a lot of misery for a couple of days (which sucks because I love bread). This cuts out a lot of things for me. I also typically do a very low-carb diet because, for whatever reason, it vastly improves my mood and how my body feels.

That said, I am moving to grow a lot more of my own food with plans to have my own chickens for eggs and eventually raising most of the meat my wife and I consume. The rest we plan on sourcing from local hunters (wild boar and overpopulated deer are big issues where we're moving) and farmers We also eat a lot of seafood, so probably less land-based meat than most already (definitely less than when I lived in the US).
