Everyone knows that there are regions of the world where certain things are considered palatable and even enjoyable but if eaten here most people would not be able to stomach it. In fact, the more I read the more I was convinced that living in survival mode the hardest part to become accustomed to would be the food.

The Most Chewy

 Though it's high in protein and minerals, and heavily used in processed meats, few of us ever try lung “meat” by itself as a food. If you try to cook lung slices, you'll quickly find out why it's not a popular item: It's as chewy as a rubber tire. In fact, I would argue that it is un-chewable by human teeth. I have both fried it and boiled it, to no avail. While I could chew it like bubble gum, and it didn't taste bad, I just couldn't chew it down small enough to swallow any of the pieces.

The Most Bitter

Tree nuts like bitternut hickory and black oak are acrid and bitter, and yet they represent some of the highest food values of the annual fall harvest. But I think the attractive, shiny green leaves of wintercress wins the battle of bitter wild foods. It sucker punches you by starting out with a taste like mustard greens, then coating your mouth with bitterness unlike any other safe wild food. Vile! Yet it is very funny when you trick someone else into eating it.

The Most Greasy

Leg bone marrow is by far the greasiest wild food out there. It's the closest thing to fast food in the wild. Just crack open some deer leg bones, scoop out the marrow and use it to fry other foods by melting it in a skillet over the fire. And, believe it or not, the marrow solids fry up like little bits of bacon. Delicious! Try it for yourself on your next hunt. There are about 1,000 calories in the marrow of four deer legs.

So that first one got me. I am not sure I could eat lung and apparently I am not the only one. Another food that is hard to disgest for me personally would be any sort of brain, eyes, etc.  Hopefully we will never have to attempt this but if you do then at least we know what is edible!
