Is Extra Protein Dangerous For Your Kidneys?

Of the entire myths that abound in the case of diet, the assumptions that encompass protein consumption and kidney injury appear to be the one everybody talks about most frequently. How did it begin? From the analysis, I did this explicit delusion began from analysis on sufferers with kidney illness. And why is that?


Folks with kidney illness have problem of filtrating protein, and that’s why in some instances they’re on a low-protein eating regimen. So, the conclusion was made that as a result of sufferers with kidney illness couldn’t filtrate protein, then it should be that an excessive amount of protein should be onerous on the kidneys. Superior proper?



In actuality, research have been finished on larger protein intakes, and the result’s that larger protein consumption is totally secure. Within the short-term, the physique adapts to the upper protein intakes which modifications some markers of kidney operate.


That is a part of the variation course of to the extra protein. Nonetheless, long-term consumption of upper quantities of protein do not need a detrimental influence on kidney operate.1,2,three,four,5


After I speak about Dr. Jose Antonio’s newest examine,2 even with the quantity of protein consumed, the writer states: “There have been no modifications in any of the variables relating to blood lipids and a complete metabolic panel.


We examined the 2 people with the best recorded protein intakes (four.66 and 6.59 g/kg/day) and located no deleterious results on renal operate in both particular person.”


We all know from earlier research that top in protein diets trigger hyperfiltration and we should always count on an preliminary improve in glomerular filtration (GFR). Glomerular what? The glomerular charge is the perfect take a look at to measure your stage of kidney operate and decide your stage of kidney illness.


However as a study5 concludes, “A nutritious diet wealthy in protein elevated eGFR (Estimated glomerular filtration is a take a look at that’s used to evaluate how nicely your kidneys are working. The take a look at estimates the quantity of blood that’s filtered by your kidneys over a given time frame.


The take a look at known as ‘estimated’ as a result of the glomeruli are the tiny filters within the kidneys. If these filters don’t do their job correctly then the kidney is claimed to have lowered or impaired kidney operate). Whether or not long-term consumption of a high-protein eating regimen results in kidney illness is unsure.”


The declare that protein consumption results in kidney stones or kidney failure will not be supported by the details.
