What is the simplest food you can survive on?

The Ultimate Survival Foods

When it comes to surviving on a single food source, context matters entirely. In terms of biological sustenance over a medium-term period, the humble white potato stands out as the ultimate candidate. This is largely due to its remarkable nutritional profile, containing nearly all the essential vitamins and minerals required to keep the human body functioning, though it requires a little dairy or fat to cover every single dietary need indefinitely.

However, the calculation changes completely when looking at long-term storage and extreme energy requirements. For enduring harsh conditions and stockpiling for the future, pemmican takes the crown. Originally developed by Indigenous peoples of North America, this traditional ration is a concentrated mixture of dried meat and rendered animal fat. It boasts incredible energy density and a shelf life that can span decades without refrigeration, making it the superior choice for true survival preparedness.
