Commercial Freeze Dried foods are convenient, but that’s about it. The 30+ year shelf life is attractive, no doubt. Some of them are pretty tasty.
The downsides: They are very expensive. Sodium levels are way, way off the chart.
And the calories are pretty low (especially for the cost). The “2 Servings” blurb on the package is apparently 2 chipmunks. They are usually pretty light on protein, and fats don’t lend themselves to the freeze drying process, so they tend to be very lean, have lots of refined carbs or added sugar to boost the calorie level.
For my money I want the staples - Flour, Rice, Salt, Sugar, Beans, Pasta, Oil, etc, packaged and stored properly.
For example Flour will tend to have pantry moths or larvae if it is not addressed. Canned goods are a much better choice for most people and aren’t so expensive. Most of what the “Prepper” vendors are selling isn’t anything a savvy shopper can’t provide for themselves.
We have both freeze dried and 5 gallon buckets with sealed Mylar bags filled with staples.
