Personally, I've reduced my food waste by eating almost primarily freeze-dried foods. They have a 30 year shelf life in most cases and just need a bit of hot water to be rehydrated, and it tastes just like fresh. The process of freeze-drying apparently keeps the nutritional value intact, as opposed to other preservation methods. It's great for planning meals for the week, and it's excellent for making delicious backpacking recipes!

It seems in any given pack of fresh blueberries/strawberries/brocolli/whatever, inevitably some part of it gets moldy or subpar eating conditions. With the freeze dried equivalent, I know I have as-good-as-fresh ingredients that won't spoil anytime soon. I don't see myself ever buying fresh berries or brocolli or chicken ever again now that I've discovered freeze dried foods. It's just too efficient and convenient to have all these good quality foods on-demand that virtually never spoil.

Edit: well actually I'd still buy fresh food... If I had my own freeze drier and freeze-dried them myself!
