Mushrooms are about 90% water, but the non-water part is indeed roughly half protein.

Say you were going to eat 8oz of beef.

How many oz of mushrooms would one have to eat to get the same amount of protein?

>56oz according to google which lists beef at 7g/ounce and mushrooms at 0.9/ounce

Edit: legumes are more practical, green peas give you 2g/oz and peanuts can be 7g/oz shelled according to google, (though they are different proteins than the beef). Mushrooms are good for texture and some like shitaki can give the umami taste, but they aren’t a nutritional meat substitute on their own.

Like 1-3kg of non-dried mushrooms?
