It is hard enough to store food that will be palatable to everyone, especially if you are prepping for a large group. It makes one nostalgic for the days of when one just ate whatever was served and were grateful to just fill the stomach. However, there are still times when special foods and preps become critical. One time is when medical dietary restrictions are placed on a person. They must stick to those restrictions or become ill, or possibly even die. Yes, it does complicate matters. When one cannot just eat an MRE or other pre-packaged commercial food.
I cannot speak for all dietary restrictions; I’m certain there are many I cannot even imagine. However, I have found some things that help with more common sugar and salt restricted diets.
Although there are many sugar free products on the market, availability would be compromised quickly if stores could not get resupplied. Obviously, a conscientious prepper will have supplies of artificial sweetener put away for emergency use. But each sweetener has its own characteristics and drawbacks in cooking. Aspartame loses its sweetness when heated and contains phenylalanine so it is not acceptable to those that are sensitive to that substance.
