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.
Cattails have almost everything to live off. Not sure if this helps also many mushrooms have various proteins.
Dear Lord, do not tell people to eat wild mushrooms! As an avid outdoorsman, you never eat wild mushrooms. It's akin to playing russian roulette. Differentiating between poisonous and non-poisonous takes a careful eye and knowledge of where they grow. Besides, other than trace elements, mushrooms are not a good source of protein, fat, vitamins or fiber. Avoid it all costs unless you are an expert.
