Grasses

• All grasses are safe to eat. You can chew on the leaves and swallow the juices, but you must spit the indigestible fibers. You can even eat grasses if you don't have water to drink.
  
  

Insects

• Grubs, grasshoppers and ants are edible. These are good sources of protein and taste good when stewed with other ingredients.
  
  

Acorns

• All acorns can be eaten as long as their bitter tannic acids are leached. Acorns are also an excellent source of fats, calories and protein. You can boil the acorns to remove the tannins.
  
  

Fish

• All freshwater fish are edible. In survival situations, you can use a sharpened stick to catch fish. For smaller fish, you can use a cloth or T-shirt as your fish net. The best way to cook fish in the wilderness is to grill them.
  
  

Birds

• All birds are also safe to eat. Game birds like pheasants and grouse can be captured with hunting elements like snares or a throwing stick. You can grill a bird or stew it with other ingredients. In spring time, bird eggs can also be an excellent food for survival.
  
  

Mammals

• Small mammals like rabbits and squirrels can be hunted with practice. You can use traps, snares or throwing sticks to hunt them. You can also have some treats with bigger mammals like wild boar, but you need strategy and practice to catch them.
  
  

Wild Fruits

• Wild strawberry, cherry, blackberry, raspberry, gooseberry, black currant, red currant and red berries can serve as your desserts in the wild. You can find and get them easily; thus, they can be your sole survival foods in the absence of other types of foods.
