Too much protein ??

Is it possible to intake too much protein on a daily basis? They say to intake 1 gram of protein per lb. of your body weight. I currently weigh 165 lbs. I am drinking two protein shakes a day, two scoops each time with 12 oz. of skim milk (apprx. 32g of protein per scoop). In addition for my second and fifth meal of the day I am eating protein bars (26g of protein). That's 180g of protein on top of my solid meals. Is this too much? Should I cut back to one scoop of the protein shake into six oz. of skim milk?
 
Now I'm not expert on this matter, but after talking to three one my friends (one doctor, one nurse, and one biology professor) I have learned that the human body can only process so much protein. Each time you eat protein, you can only process around 30g(give or take, depending on the person). Anything over that just gets excreted with your urine.

From what I have read, for someone who regularly lifts, you should be getting 1.0-1.2 grams of protein for each kilogram you weigh. Since 1kg=2.2lbs, you should be getting 75-90g of protein per day. Now obviously is depends a little bit from one person to another, but this is a good general rule. I would say you can take it down to the low 100's and be getting all the protein you need, and then some, and save yourself some money in the process.

EDIT: After doing some online research, I found that almost every website reccomends between 80 and 100 grams for someone of your weight who does regular weight training. There were a couple sites that said as high as 132 for you, but that was by far the highest.

common recommendation for those hitting the weights runs from roughly .8 grams per pound of bodyweight up to 1 gram per pound of bodyweight.

some ppl go even higher and consume upwards to 300 to 500 grams a day. crazy, i know.

if you have pre-existing problems with your kidneys, you need to take care. otherwise you're fine as long as consume plenty of water and even fruits and veggies can help out. :)

Is that worth it though? Does all that protein really help?
 
IMHO, over 300 is not necessary, not for us anyway. personally, i've been taking in around 200 grams for years (i'm at 178lbs now.)

if one gets results with 100 grams, then there is no reason to take in more. i tell ppl to experiement, start low and see how you do. :)
