Protein is not a nutrient that anyone is deficient in. Any plant that humans eat provides enough protein if you consume enough to meet your calorie requirements. You have never met a person who is in protein deficiency who was not also literally in starvation from not having eaten. The whole “we need a cheap source of protein” thing is a myth. It’s everywhere, it’s inescapable. It’s literally the building blocks of all life on Earth. It’s like people in the 50s extolling the health virtues of smoking, it’s pure marketing bullshit that we have become completely steeped in.
