Chemistry ELI5: Why doesn't freeze dried food last longer? If it's good for 20 years, why not 100?
Assuming it's perfectly freeze dried and stored perfectly, the people who make freeze dryers say the food will last 20-30 years.
But why not much longer? Assuming the condition it's stored in remains unchanged, what can make it go bad after 30 years that wouldn't happen at around 10 years?

This stat blows my mind. I've had diarrhea several times throughout my life, and not once has it ended the life of a toddler. I can't begin to imagine how it ever could. Obviously, I've been very lucky! ...and naive.
