My opinion, for what it is worth...is that while times are good,
you should learn to eat things that are preservable.
Adjust your routine to NOT rely on fresh or frozen foods, and adapt
your routine to things like boxed, dried, and canned foods with a long shelf life.
Have a goal to keep a 6-12 month supply of those foods.
Buy them periodically and be sure to rotate your stock.
That way, no matter if times are good or bad,
you eat the same thing you always eat, and
you don’t have to get used to eating something different.
Watch out for expiration dates if you are keeping “emergency supplies”.
This week I ate my sardines that expired in 2015. Indistinguishable from the ones I ate the week before that expired in 2010.
