Of course turkey is paleo. Nothing more paleo than eating one of those huge turkey legs roasted over a hickory wood fire, if you ask me; meaty, fatty, sinewy, and packed with flavor. Ground turkey is somewhat boring in comparison but as a whole, turkey is a wonderful choice. Why wouldn't it be paleo? It's a bird is it not? Or is there something I am missing?
Some of the stuff I had bought in the past had "Ingredients: ground turkey, natural flavor" - as we know, they can hide quite a bit of objectionable stuff under natural flavor. If yours is just ground turkey, go for it. (This was a major CAFO brand, not buying it anymore obviously.)
Whole turkey is wonderful stuff, especially once you've got it down to the bones and make a bone broth to make soup out of the leftovers. Ground is fine too, but you just don't get all the goodies like the organs and bones.
Ground turkey's useful for making meatloaf: dice an onion, garlic, and some tomatoes (or sauce), maybe some A1, throw in a couple of eggs, some coconut/rice flour, maybe some melted butter, oregano, basil, salt, pepper, and other spices, and mix the whole thing by hand, place in greased containers with bacon rashers on top, and bake at 375F for about an hour.
I don't eat it because of the quality of what is available. Not because of the good or bad Paleo issues. I'd much rather use Grass Fed ground beef. If I have turkey it is from a roasted whole turkey or sometimes the breast only. . . but I do like to make Turkey soup so the bones are precious. I cringe when I see someone throwing the carcass out.
It's kinda high in PUFAs, like chicken, but once in a while should be fine. Like any other meat, the conditions in which the animal is raised and what it is fed will affect the quality and fatty acid profile of the final product.
