In a previous thread I mentioned a swamp survival course I took. Grubs, snails, minnows, and other creepy crawlies were a mainstay of my diet for a week. All are high in protien. And yes, cooking most is recommended. The white beetle grubs and hoppers were best. Sometimes I made a stew of my day's find, rather than using each variety as an individual course. Adding a few wild seeds, berries, some chopped roots etc. and boiling for a few minutes in a canvas "bag". Bark would work as well. A snake or small bird was a welcome addition to the meal, usually roasted on a green stick. I actually gained weight on this diet, mostly because I didn't hesitate to start gathering and consuming, rather than waiting until I was having the second hunger pains. Earthworms are another good source of protien. Drop them in water and let them clean themselves out firs, usually a few hours. Unless they are big enough to split open and wash. I don't recommend eating anything dead, though. You can eat some putrid meat after a thourough washing and cooking, but it is playing Russian roulette, and a long way from a stomach pump!
