Water
The human body can go 3 weeks without food but only 3 days without water. If you do not have a fresh water supply nearby, make sure you have a few gallons of drinking water available.
Canned Foods
The canned food section is where you can get a majority of the food that you can easily stockpile for years, better yet, can your own food! Anything from fruit and veggies to meat and beans, canned foods can last for years. But consider their weight; if you have to travel, canned foods will not be a good idea.
Dried Meats
Whether you buy the stuff in bags or make it yourself, meat is a huge protein and energy source in times of disaster making it one of the best survival food.
MREs
For those of you who have ever eaten one of these in the military, present company included, you know that these are not the most satisfying of meals. However, these freeze dried feasts are making a comeback, available for purchase at such retailers as REI and available in a Paleo version.
Protein Bars
These are great options for bug out bags as they can be used as meal replacements and they are light. Since there are so many brands available, buy a couple different ones and see which one is your favorite.
Wheat Flour
Even without a leavening agent like baking powder or yeast, wheat flour can still be used to make bread. Simply mix flour, water and salt for a cracker like bread known as hardtack. It is also a source of carbohydrates and protein and can be stored for up to 2 years in a pantry.
Oatmeal
With a shelf life of 30 years, oats may be the best food you can stockpile. Oats can be prepared with nothing but boiling water for a filling meal. In a time of crisis, oats can also be used for animal feed and can even be ground into flour.
Salt
Salt is a multi-tool that every survivalist needs in their arsenal. It can preserve food, treat wounds and add flavor to meals. Your body does not produce sodium, but it needs it. If you are not getting sodium from animal products like meat and milk, add salt to your food to maintain proper health.
