Kidneys and Liver


There are many rumors about protein in the world. We are not talking about the protein supplements that some people call protein and have no knowledge that protein is present in different foods. Yes, there are many people who do not know that protein supplements are derived from food. Whey-protein, BCAA, and amino acids, for example, extracted from milk. When we talk about protein, we talk about food and protein supplements.


Protein is a total of 20 amino acids. 9 essential acids must be obtained from an external source (of food) and 11 non-essential acids can be manufactured by the body itself. 


Protein is divided into two types, namely, whole protein and incomplete protein. The whole protein contains 20 fully amino acids, namely animal protein such as meat, dairy, and eggs. The incomplete protein is vegetable protein and lacks amino acid or two. You can mix several vegetable protein sources together to get a full protein amino acid meal. However, animal protein remains an important source of protein, especially for bodybuilders and those who walk on a diet for slimming. As the body benefits more animal protein and produces less protein waste than vegetable protein.


 Protein has great benefits for muscle building, slimming and improving health. High protein dieting is not only necessary for bodybuilders to build muscle. But it helps dieters to slim faster by increasing metabolic rates and eliminating hunger during dieting.


What is the relationship of protein to kidneys?


What is the relationship of protein to kidneys


When the protein is taken, it is broken down into amino acids. When you eat excess amino acids, they become nitrogenous wastes that the kidneys dispose of in the urine. Additional information, the body benefits more than 30 grams protein of the meal. The story that the body benefits only 30 grams protein meal, just a myth.


What are the effects of high protein diet on kidney patients?

Have you noticed the address? I am now talking about kidney patients, not healthy, Gaelic in the way. In 1997, there were 255 patients with kidney disease who were shown to have improved kidney status with a low-protein diet.


Another study conducted in 1996 recommends that kidney patients should not exceed 0.6 grams of protein per kg of body weight so as not to deteriorate the health of their kidneys.


These studies do not mean that kidney patients stop eating protein completely. This is because protein is a basic food element needed by the body for health and life. If you do not eat protein, your health will deteriorate, including the health of your kidney. Consult your doctor for the amount of protein you should eat. This is because the amount of protein depends on your size, age and the progress of your illness.


In short, your kidney status depends on the GFR index, which is the Glomerular filtration rate, which is the ability of your kidney to filter waste. This percentage can be measured in any laboratory. Kidney patients are divided into 5 stages.


The first phase of the GFR is higher than 90, which is the normal number of human, but with abnormal measurements of protein in urine.


The second stage of the GFR is from 60 to 89


The third phase of the GFR is from 30 to 59


Phase IV GFR from 15 to 29


The fifth and final stage is GFR less than 15 and total renal failure.


In fact, in the fifth stage, renal failure, there is no need to reduce the protein because the patient is doing a continuous renal dialysis to remove all the wastes from the diseased kidneys. On the contrary, the need for protein increases because of the removal of many important amino acids from the kidneys during washing.


In the case of patients with kidney disease due to diabetes. The doctor should choose the amount of protein that balances blood sugar control and prevents deterioration of kidney condition.


Another important tip for kidney patients:


Because of kidney disease, phosphorus accumulates in the blood abnormally. Therefore, proteins containing phosphorus, such as yogurt, yogurt, cheese, beans, and nuts, should be reduced.


What are the effects of high protein diet on healthy kidneys?

It does not mean that high protein dieting causes deterioration of kidney health, it will negatively affect your kidney health. Increased intake of sugar adversely affects the diabetic for example. But increasing sugar does not affect you negatively (within reason).


Is protein a pressure on the kidneys?


Kidneys are always under pressure. 20% of the blood pumped into your heart goes to the kidneys. Your kidney will filter 180 liters of blood daily! Yes increasing the amount of protein adds extra effort to the kidneys. But it's a little extra effort compared to the effort your college makes every day.


Increased kidney effort is also called Hyperfilteration. That is, your kidney increases the filtering process naturally. Studies have shown that increased renal filtration is a normal reaction to the body and is not indicative of any potential risk. Pregnant women, for example, increase their total filtration by 40 to 65% for 9 months and are not exposed to any risk. The person who donates the whole kidney increases the filtration process in his remaining kidney and lives all his life in one healthy faculty.


And no research or study has observed any negative effect of increasing the amount of protein on the healthy kidney. This is a major study carried out in 2004 and published in the Journal of the International Society of Nutrition Sciences. There is no evidence that high protein dieting has any damage to the liver, kidney, bone health or blood pressure. On the contrary, this study found a correlation between increased blood pressure and increased risk of osteoporosis than the few protein recommended by some US institutions and 0.8 grams protein per kg.


Another study, which discussed 111 old and recent studies on the effect of high-protein diet on kidneys, found no negative effect of protein on intact kidneys. You can click the link and read the study summary yourself.


In fact, the two biggest causes of kidney disease are diabetes and blood pressure. Where hypertension causes 30% of kidney disease. High-protein diets protect you from these two diseases. (Studies 1, 2, 3, 4 ). Even if we assume that high-protein dieting is harmful to the kidneys (just presumed), its benefit to the kidneys is greater than the damage to the kidneys.


What are the effects of high-protein dieting on the liver?


In the case of liver patients, the protein is not properly represented, and high protein diet may cause the accumulation of nitrogen residues in the brain. Source . But you should also consult with your doctor to determine the amount of protein suitable for you. Because in some cases of liver disease and after liver transplantation, doctors recommend increasing the amount of protein to build new cells and fibers in the liver rather than damaged.


In the case of healthy liver, no study showed a negative effect of high protein diet on the liver.


What is the biggest cause of diabetes, hypertension, heart disease and high cholesterol?

Studies have shown that the biggest factor that leads to doubling the risk of these diseases is eating


Higher than the TDEE for long periods of eating unhealthy foods. In the case you eat fewer calories than the TDEE it protects you dozens of diseases even under poor environmental conditions in which we live and in light of eating harmful foods ( of course, would not recommend eating fast food just because you cut Saratk, I just tell you the results of the research).
