EAT, PEOPLE CHOOSE TO STARVE.
The first thing you need to know is, when walking through the woods you are walking through a sea of food. Some of it is of little or no nutritional value to you, some is toxic to you, and some is good for you, it just may be disgusting. Anything you see, you can eat. It just may make you sick if it is the wrong thing, or be of no value to you. When you eat a food of little nutritional value, your body consumes calories just to digest it, and you starve faster than you would if you did not eat. Remember the forest is full of food so sit down and eat your bowl of maggots. If that disgusts you, now you know why people choose to starve, they won’t eat their maggots.
YOU CAN EAT ANY MUSHROOM, ONCE.
That does not mean you will live to eat it a second time. A person can eat a mushroom one-day with no ill effect and it will kill them the next time they eat it. The list of polypore and edible mushrooms you can eat would fill an encyclopedia set, and the list of polypore and mushrooms that will kill you or make you sick is just as large. A good field book on picking common wild polypore and edible mushrooms is your best bet to avoid problems with eating mushrooms from the wild. Some mushrooms are good to eat, some will make you sick, some will get you stoned, and some have medicinal value.
