Can powdered whey protein be stocked long term as an emergency food supply and substitute animal protein if there's none avaliable ?
EDIT: Asking on behalf of a couple friends who drink it every day in the gym and said they could fetch a good supply on short notice if it's useful.
If stored properly, yes. It has a shelf life of about a year, but will keep as long as 18 months in cool, dry conditions. It will provide you the same nutrition as cooked meat in a pinch.
