A few, almost traditional survival foods include; jerked meat and pemmican, dehydrated foods, with fruit being the most readily purchased and even fruit cake. One should remember that in a long term survival scenario the body is already under stress. Major dietary changes, no matter how nutritous or beneficial can negatively affect us. Foods prepared for storage( dehydrated,freeze dried etc.) have had the water content reduced to save wieght and extend shelf life. Remember, when you eat this food that water must be replaced,either in preparation or intake. Canned foods are heavy ( water content), also subject to heat and cold degradation and may have elevated sodium levels. Worldwide we are playing a big gamble with food, relying on a handfull of major crops ( rice,wheat,soy and corn) of decreasing genetic diversity. I like to play out the opposite strategy in my own reserve supplies; foods in several stored mediums of a wide variety. Think like a gourmet omnivore, nothing is worse than going on a long hike and finding everyone brought granola <img src="images/graemlins/tongue.gif" alt="" /> Some foods can be a nutritional suprise also. Captain Cook introduced limes into the hardtack and salted beef rations to eliminate scurvy. His german peers never knew the malady, a common shipboard ration being easily stored saurekraut <img src="images/graemlins/shocked.gif" alt="" />
