Is Extra Protein Dangerous For Your Kidneys?

Of the entire myths that abound in the case of vitamin, the assumptions that encompass protein consumption and kidney harm appear to be the one everybody talks about most frequently. How did it begin? From the analysis, I did this explicit fantasy 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 completed on increased protein intakes, and the result’s that increased protein consumption is totally protected. Within the short-term, the physique adapts to the upper protein intakes which adjustments 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 research,2 even with the quantity of protein consumed, the creator states: “There have been no adjustments in any of the variables concerning blood lipids and a complete metabolic panel.


We examined the 2 people with the very 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 enhance in glomerular filtration (GFR). Glomerular what? The glomerular charge is the most effective take a look at to measure your degree 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 effectively your kidneys are working. The take a look at estimates the quantity of blood that’s filtered by your kidneys over a given time period.


The take a look at is named ‘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 just isn’t supported by the info.
