that sounds round up to me as I have heard more like .7 or .8 and even then im not sure how much its nudged up by modern mania around it given how common it may have been in history and even then it should be based on where your weight should be as opposed to at to me. eggs have 7 or 8 grams and a burger can have 20 or 25 grams. Plants have protein to and a serving of rice and beans can be like 15 to 20. Im betting the average american without trying eats 80 grams or more of protein a day.
