Sick kidneys due to meat
The kidneys do not seem so enthusiastic about a rich meat consumption. We had already reported in detail about the growing risk of kidney cancer, which occurs when a lot of meat is eaten, for example, kidney cancer by meat
Other types of cancer are also more frequently observed in people who eat a lot of meat, such as stomach and uterine cancer, liver cancer, lung, esophagus and pancreatic cancer, as well as bladder cancer.
A new study was published in July 2016 in the Journal of the American Society of Nephrology (ASN), which showed that renal insufficiency (kidney failure) can also be associated with meat consumption. In renal failure, the kidneys gradually begin their work and filter the blood inadequately.
In renal failure: less protein or just less meat?
The scientists were motivated by the currently growing number of people suffering from chronic kidney failure. In many cases the condition of the renal function deteriorates continuously, until finally they reach the 4th stage of renal insufficiency (terminal renal insufficiency). Now only the dialysis or a kidney transplant remains.
Normally, in renal failure, it is recommended to consume fewer proteins to keep the disease in check and to prevent or delay delayed renal insufficiency. However, concrete scientific evidence for this recommendation has so far been lacking. For example, one did not know whether one should generally limit protein consumption or only the consumption of special foods.
To gain a little more clarity, the team around Dr. Woon-Puay Koh from the National University of Singapore analyzed data from the Singapore Chinese Health Study, a study of 63,257 adults from Singapore. 97% of the consumption of red meat consists of pork. Other sources of protein are poultry, fish, seafood, eggs, dairy products, soya and legumes.
Meat damages the kidneys, soy protects the kidneys
After an observation period of 15.5 years, the Singapore study showed a clear link between the consumption of red meat and the occurrence of chronic kidney failure: the more red meat a person ate, the more likely it was that she was ill in the course of her life Kidneys.
Those who ate the most red meat had a 40 per cent increased risk of developing renal failure when compared to those who took the least meat.
There was no association with other animal protein sources in this study. Soy products and other pods appeared to protect the kidneys.
More plant based protein for the protection of the kidneys
Any meat meal replaced by another protein source can significantly reduce the risk of kidney failure, according to researchers.
Dr. Koh explained that people with chronic kidney failure or the healthy general population for the protection of kidney health should not advise reducing overall protein intake. It is recommended, however, to carefully select the type of proteins, namely, to increasingly rely on plant protein sources. Whoever wants to eat animal protein, should stick to fish and poultry.
