This is true. We have been at it for 6 years. We just picked up more sugar the other day. Now I am working on Toilet paper which for some reason I just have not stockpiled. We use the 5 gallon buckets with mylar bags then go to Costco and get a 25-50 lb bag of sugar and then fill up a bucket and seal it shut.
Folks need to remember canned meats and fish.You need about 50 grams of protein a day to remain healthy.Dried beans or rice is good too.
