> Too much protein can definitely kill you, or at least make you ill, as discovered by the Europeans who explored the northern parts of America and who had initially tried to live from the meat of hunted animals, until they learned from the natives that they must eat enough fat besides the lean meat, in order to survive (most wild animals have little fat, except the bone marrow, which must be extracted).
That's an issue of too little fat, not too much protein. The question is whether, when your other nutritional needs are being met, an excess of protein is an issue.
