Re: Too much protein bad for kidneys?
Too much protein can definitely be hard on the kidneys, but for your stats, that isn't too much protein if you're active and/or working out. However that IS too much to be getting from shakes. Shakes should be used as a supplement to diet, not in place of diet. Like any nutrient, protein is best obtained from real food. Is there a reason you drink so many shakes instead of eating real food?
