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.
You can but it isn't ideal as a a source of protein. It is best used as a supplement to get more protein into a diet that already contains it. Also most types of whey don't digest particularly well and can upset your stomach.
