    Dietary protein intake and renal function.

    Abstract
    Recent trends in weight loss diets have led to a substantial increase in protein intake by individuals. As a result, the safety of habitually consuming dietary protein in excess of recommended intakes has been questioned. In particular, there is concern that high protein intake may promote renal damage by chronically increasing glomerular pressure and hyperfiltration. There is, however, a serious question as to whether there is significant evidence to support this relationship in healthy individuals. In fact, some studies suggest that hyperfiltration, the purported mechanism for renal damage, is a normal adaptative mechanism that occurs in response to several physiological conditions. This paper reviews the available evidence that increased dietary protein intake is a health concern in terms of the potential to initiate or promote renal disease. While protein restriction may be appropriate for treatment of existing kidney disease, we find no significant evidence for a detrimental effect of high protein intakes on kidney function in healthy persons after centuries of a high protein Western diet.

    First, should be noted that I presume the OP isn't pregnant.
    Then - this link is rather alarmist and makes few real points. The first reason it gives not to eat lots of protein is because if you do you'll eat too many calories and too many calories=fat. Well, duh; I'd hope most on MFP understand that eating too much food makes them fat :).

    The liver function has a 'may' - and yes, if you have other problems, this MAY be an issue.
    Just as if you have an allergy, eating peanuts may be deadly.

    The last one is not only based on rather questionable science by modern standards, but also not against protein per se.

    This is 13 years old. I can't believe even they they couldn't find evidence that a high protein diet beniftted bodybuilders.
    Athletes that didn't do strength training, sure I can understand that.
    "Taking in excess protein means you'll just be excreting it," Pagenkemper says. "Basically, high protein is just an expensive way to feed yourself."
    It also say they can't know what the right amount is.

    So I believe the logic behind your claim people may end up getting too much protein is faulty.

    MFP is a guideline only.
    If I go over protein or fiber, I don't consider it a bad thing. For me, those are just minimums. I watch calories, carbs, and sugars and try not to go over on those though. Fat too, unless I ate avocado or nuts that day :)

    Don't stress it :)

    If you go too far over on fibre you may end up doing a poo in your pants.
