Show me a scientific research that concludes that high amounts of Protein are harmfully. Protein consumption will be maximazed in small doses during the day, providing constants supply of amino-acids. The consuption of 100g of Protein will certainty decrease its absorption, but so will ANY substance taking in excess. Small doses of 30g to 40g during the day are optimal.
Why are you asking me, when you have a google right under your nose? Try it, and you will find just those answers you like. If I do the search, you don't like what I find. You can try to figure that question out by thinking what happen to protein you eat. You seem to think that it goes right to your muscles and make them bigger, but that isn't all what is in to it. You body chop proteins to amino acids, which you can utilize in your system up to a certain amount. How about that extra amount of amino acids which you have eaten. Where that goes? Where those protein farts comes and what make them smell so bad, like you has been decomposed inside? Well, If we simplify the subject to the max and beyond, all the way at the point where it is simple enough for you to understand, that is just what has happen. Excessive protein goes bad in you digestion and it produce gas, ammonia etc. in your system, and only history will prove what will be long term effect to all that, because there isn't any study about teen nerds who has too high protein intake. You guys always miss the big picture: It isn't just smoke, booze, pollution, yellow snow or excessive protein, but all that shit together in your system. What ever you eat today, will probably kill you 10 years from now, so if you want to live to see your first pubic hair, you must be very careful.
