Too much protein will lead to premature kidney failure by way of amyloidosis (systemic protein deposition), over filtration requirements, etc. The average young healthy person (male) can only use 40-50g/ day which is easily obtained in your diet. Food for thought...American urine is the most expensive in the world. True story.
"Most adults would benefit from eating more than the recommended daily intake of 56 grams, says Donald Layman, Ph.D., a professor emeritus of nutrition at the University of Illinois."
I'll listen to a doctor before I listen to someone who doesn't know what they are talking about. It is very healthy if you work out consistently to consume .5g of protein per pound of body weight. So since I weigh 160 I will continue consuming 80 grams of protein a day. This would be too much protein if I wasn't working out every day.
