What are the best foods to eat if you are lost in the woods?

You can eat leaves and stuff but a lot of it is indigestible. You are not supposed to eat any fruit, nut, or berry you don't recognize. You can test a berry or fruit by taking a piece and touching the inside to your lips. Wait 5-10 minutes. If there is any stinging, swelling, or anything unusual, it is not safe to eat. If it safe to eat, take a little piece and start mashing it in your mouth for a few minutes and swallow. If there is any tingling, stinging, swelling, etc., don't eat it. If it passes this test, it is safe to eat, so you don't have to worry about dropping dead after eating it.
