Hi Hugh,
I have been fortunate enough to have met and talked to a number of Preppers and others preparing in the event TSHTF. One of the common things I’ve learned from them is the value of a food with a very high caloric and energy content. They have all shared that oils (Olive, Avacado, et cetera) are one of the most difficult items to procure in nature. They also happen to be the most dense food. In other words, an ounce of edible oil has far more calories then an ounce of protein or an ounce of carbs.
For those attempting to survive on low-calorie dehydrated or freeze-dried meals, do the following: Add a teaspoon or two, or three, to the soup (or food) you are preparing. A few tablespoonfuls can easily double the caloric content and energy available in a meal. I’ve done that in the Sierra Nevada when I’ve been backpacking for over 30 years. It works great! So be sure to stock up on as much edible oils as possible. Keep them sealed and in the dark. – M.A.
