In a survival situation, one has to make the most of everything available to eat. Most wilderness areas are abundant with natural food, ranging from plant varieties to insects as well. The food source available to you in your particular situation depends on the type of habitat you find yourself in.
The trick is to vary your diet to ensure you receive the appropriate nutrition that includes protein, fat, carbohydrates, vitamins, and minerals. Fish and meat are great sources of fat and protein and provide nearly everything a survivor needs, but it’s also the hardest food to find and catch. However, don’t concern yourself with meat just yet, as in the first stage of survival, plants are the best source, due to being easily accessible, and they contain the required carbohydrates as well.
