Animal protein vs Plant protein for our Kidneys

Important points :

"Anti-inflammatory drugs abolish the hyperfiltration and protein leakage response to meat ingestion, suggesting that animal protein causes kidney stress through an inflammatory mechanism."

"Between 1990 and 2010, some of our leading causes of death and disability haven’t changed. Heart disease was the leading cause of loss of life and health then and remains the leading cause today. Some things got better, like HIV/AIDS, but others got worse, like chronic kidney disease, a doubling in the tens of thousands of deaths and the hundreds of thousands whose kidneys fail completely, requiring kidney transplants or lifelong dialysis. About one in eight of us now have chronic kidney disease whether we know it or not. And, most of those with kidney disease don’t know it—about three-quarters of the millions affected are unaware their kidneys are starting to fail, which is particularly worrisome given that early identification provides an opportunity to slow the progression and alter the course of disease."

"Animal protein intake has a profound effect on normal human kidney function, inducing what’s called hyperfiltration, increasing the workload of the kidney."

"This may help explain why our kidneys fail so often. Unlimited intake of protein-rich foods, now generally regarded as “normal,” may be responsible for dramatic differences in kidney function between modern human beings and their remote predecessors who hunted and scavenged for meat here and there. Sustained, rather than intermittent, excesses of protein require us to call on our kidney reserves continuously, causing a kind of unrelenting stress on our kidneys that can predispose even healthy people to progressive kidney scarring and deterioration of kidney function. On the other hand, administration of an equal quantity of vegetable protein does not appear to have the same effects."

"Eating meat, for example, increases the workload on the kidneys within hours of consumption, but apparently, taking care of plant protein appears to be a cinch."

"Short-term studies have indicated that substituting plant protein, like soy, for animal protein is associated with less hyperfiltration and protein leakage, therefore, slowing deterioration of kidney function. However, the long-term effect had not been adequately studied, until this study was published in 2014. A 6-month double-blind, randomized, placebo-controlled trial, soy versus dairy protein, and the consumption of whole soy tended to preserve renal function compared with milk in individuals with lowered renal function. Similar results were reported in diabetics. Even just giving isolated soy protein appeared to make things better, compared to dairy protein which made things worse."

"What is going on? Why does animal protein cause that overload reaction, but not plant protein? It appears to be an inflammatory response triggered by the animal protein. We know this because administration of a powerful anti-inflammatory drug abolished the hyperfiltration, protein leakage response to meat ingestion."
