This was such good information around protein and kidney disease, I needed to copy and paste it here. The focus is about SALT but lots of information on how protein matters. Both high protein, and animal protein contribute to kidney disease.

Kidney Disease and Diet - Sean Hashmi MD
(My lecture notes)
Since the 1980s there have been no pharmaceutical discoveries around management of kidney disease. Sadly medical management hasn’t changed either. Furthermore, is some bad dietary advice being given that hasn’t kept up with research on the impact of food.
Quick facts:
• 20% of people on dialysis die every year
• The five year dialysis death rate is 50%!
• None of this data has changed in almost 40 years
• One in seven people have kidney disease (KD).
• Three main causes of KD are hypertension (high blood pressure), diabetes and excess body weight.
• Kidney disease kills more people than breast cancer or prostate cancer.
• There are no obvious pain symptoms of kidney disease. “I'll have people come into my office that just felt tired, and they're on the verge of death.”
• Salt (sodium) is a major risk factor for kidney disease. Salt added at the table only accounts for 7% of dietary sodium. The remainder is found in prepared and processed food.
• Hypertension is a primary risk factor for KD. Increasing sodium by only one gm/day raises blood pressure as much as 26%.
• Reducing sodium by one gm/day is equivalent to the effects of the average hypertension medication.
• Protein in urine is a clear indicator of decline in kidney function
• Restricting salt dramatically reduces protein in the urine (up to 50%)
• While high potassium levels are a concern for a few patients, potassium helps lower blood pressure. A whole food plant-based diet is rich in potassium and this diet has been proven to reduce blood pressure. A simple blood test will tell your doctor if you need to be concerned about too much potassium.
• The standard American diet (SAD) is the one lowest potassium diets and those eating SAD and are at 44% increased risk of new chronic kidney disease versus diets rich in potassium.
• SAD leads to loss of potassium and calcium due to higher acid levels resulting from this diet.
• Supplementing with calcium appears to lead to calcification of blood vessels.
• Phosphorus: Caution. Dietary phosphorus increases death risk. Plant-based foods contain similar amounts of phosphorus as animal foods, but phosphorus absorption is 50% less than with animal foods.
- Protein -
• Animal-based protein is very damaging to kidney function
• Reducing protein reduces risk of dialysis, chronic kidney disease and death.
• Dietary recommendation for protein is 0.8 gm per day.
• A 2009 study found reducing protein to 0.6 gm per day reduces risk of death by 32%!
• Low protein diet in non-diabetics led to a 33% reduction in protein in the urine.
• Insulin dependent diabetics saw 44% reduction in protein in the urine from a low protein diet.
• Plant-based proteins have opposite effect to animal proteins on the kidneys. Less protein spillage takes place.
• Kidney function continually declines with age. Unlike other tissue, the body has no ability to generate new kidney tissue.
• Soy is the best protein source for kidneys and for kidney disease.
• Red meat is the worst protein source for our kidneys.
• Soy protein is a good news story for the kidneys, and is likely a better protein source than other plant proteins.
- Other Nutrients -
• TMAO: (from carnitine in animal based foods) is not only a concern in heart disease and atherosclerosis, but also impairs kidney function. It actually creates a vicious cycle of increase serum TMAO.
• Saturated fat: The evidence is clear. Decrease saturated fat
• Fibre: Increase dietary fibre! Fibre is found exclusively in whole plant foods. There is nothing but good news about fibre where our kidneys are concerned.
• Average Paleolithic fibre intake was 80 to 100 grams daily, compared to current American intake of 10 gm/day.
• Sugar is bad, but artificial sweeteners are even worse. As you progress to increased sugar in your diet to use of artificial sweeteners you see increased risk of renal disease, and dialysis.
Bottom line message is eat as close to a whole food, plant-based diet as possible.

From the Physicians Committee for Responsible Medicine (associated with Doctors from George Washington University Medical school):"It's easy to get all the protein you need without eating meat, dairy, or eggs. An average woman needs about 46 grams of protein per day; the average man about 56."

BTW: I am more impressed with the WHO's research because it is not funded by big meat industry dollars, nor are their leaders being injected with large meat industry lobbying dollars as are our politicians.

From Forks Over Knives website:"It's easy to get all the protein you need without eating meat, dairy, or eggs. An average woman needs about 46 grams of protein per day; the average man about 56."

Dr. John McDougall: "The final tally, based on solid scientific research, is: your total daily need for protein is about 20 to 30 grams. Plant proteins easily meet these needs....Those living in many rural Asian societies consume about 40 to 60 grams from their diet of starch (mostly rice) with vegetables...Processing all that excess dietary protein – as much as 300 grams (10 ounces) a day –causes wear and tear on the kidneys; and as a result, on average, 25% of kidney function is lost over a lifetime (70 years) from consuming the Western diet...The time-honored fundamental treatment for people with failing kidneys is a low-protein diet...People suffering with liver failure are also placed on diets low in protein as fundamental therapy – short of a liver transplant, this is the most important therapy they will receive. "
