The reason people add preservatives to food is to extend its shelf life, which makes it more profitable.
When you are in a survival situation, food with a long shelf life is critical.
That is why I think people who think that natural foods are part of a good survival program are mistaken.
Once you are rebuilding a new world on your 40 acres, then maybe you will be forced to do natural farming, but until then, I would say that
preservatives are your friend.
Before refrigeration and modern storage methods like canning people ate the worst things and had a very high salt intake.
There is no magic bullet if the power goes out. You either have to learn the old methods, or hunt every day.
But maybe there are some new methods as well. Honey is an antibacterial agent because it has hydrogen peroxide in it. Yet people would say, honey is a
natural preservative.
They wouldn't dream of preserving food with hydrogen peroxide.
Honey will keep forever but it is no good as a preservative of other things, because once mixed with other foods it loses its ability to preserve
since it works by lack of water. Honey has very little water so bacteria cannot grow.
But honey is pasteurized. And some people would say, well I like raw honey because it is much better for you. Thats a typical myth, because the reason
it is pasteurized is to kill botulism spores which are often found in honey.
Infant botulism has been associated with honey contaminated with botulism spores. Mothers are warned not to feed raw honey to their infants, as
Clostridium botulinum spores in honey have in a few cases resulted in infant botulism.

I think when it comes to surviving, if hydrogen peroxide works then I want to know about it.
In the old days, we have to remember that there was a very high infant mortality rate.
And life for most people, was brutish and short.
