Can Protein Put Strain On Your Kidneys?

You may have heard erroneous reports how ‘too much protein will put unnecessary metabolic strain on your kidneys’, but the truth is this…THESE CLAIMS ARE UNFOUNDED. In other words, there is no substantive evidence to suggest that a protein intake in excess of 1.4-2.0g protein per kg body weight will cause strain on the kidneys. Yes, people consume in excess of this, but this should be done methodically and under expert supervision (if at all), as always it is at the consumers discretion.

With anything it is moderation, due care and attention, and staying abreast of current information that counts. With regards to whether protein (in the above mentioned quantities) puts strain on your kidneys…the answer is a resounding NO!

    while i totally agree with this; with a small execption i must add.
    i work in a small local gym where a lot of the lads want to look good and add abit of size. so i naturally give them the required exercise regime's along with, in most cases some instruction to up there protein uptake. to be sure i was right i put a fair bit of research in, but also because i have CKD STAGE 3A, and thru personal experience when i get to a certain levl of daily protein intake my kdney count drops. this meaning i really had to make sure i wasn't giving these lads info that could eventually damage them. i have found todate no evidence of high levels of daily protein intake having an effect on healthy kidneys.
    however if you believe or know you have any underlying kidneys problems, then best to have a checkup before undertaking a high protein diet.
