One Tip on how to keep your kidneys healthy always

Eating red meat may boost the risk for kidney failure, but swapping even one daily serving of red meat for another protein may reduce the risk, a large study from Singapore suggested.

Red meat intake is strongly associated with an increased risk of end-stage renal disease, the loss of normal kidney function. The relationship was also "dose dependent", which means the higher the consumption, the greater the risk.

The association held up even after compensating for factors that could skew the results, such as lifestyle and other health conditions, the study authors noted.

"Our findings suggest that patients with chronic kidney disease or the general population worried about their kidney health can still maintain protein intake but consider switching to plant-based sources," said Dr Woon-Puay Koh, professor in the office of Clinical Sciences at Duke-NUS Graduate Medical School in Singapore.

"However, if they still choose to eat meat, fish, shellfish and poultry are better alternatives to red meat," said Koh, one of the study authors.

The study adds new data to a conflicting body of evidence on the relationship between protein in-take, particularly red meat, and kidney disease, experts noted.

"It adds useful and additional information to our knowledge base, but I'm not sure if it necessarily tips the scale one way or another," said Dr Allon Friedman, a nephrologist and associate professor of medicine at Indiana University School of Medicine in Indianapolis.

"My opinion is that it's still perfectly fine for individuals who are otherwise healthy to consume red meat in moderation," he said.

Dr William Mitch, professor of nephrology at Baylor College of Medicine in Houston, said that plenty of studies have shown that low-protein diets may benefit people who already have kidney damage.

However, in the general population, there's no persuasive evidence that eating a lot of protein causes kidney damage," he said.

Red meat has been implicated in recent reports and studies as potentially harmful to human health. The World Health Organisation (WHO) last year warned of a possible link between red meat and cancer. Similarly, a November 2015 study in the journal of cancer found that meat cooked at high temperatures could potentially affect kidney cancer risk.

For the new study, researchers followed more than 63,000 Chinese adults in Singapore for an average of 15.5 years.

The food questionnaires were used to gather data on people's daily protein consumption. The records on the incidence of end stage renal disease came from a nationwide renal registry.

About 97 percent of red meat intake in the study population consisted of pork. Other protein sources included poultry, fish, shellfish, eggs, dairy products, soy and legumes.

Although pork may appear white after being cooked, but it still considered red meat, said the US Department of Agriculture.

People consuming the highest amounts of red meat had 40 percent increased risk of developing end stage kidney disease, compared with people who ate the lowest amounts, the study found.

No association was found with poultry, fish, eggs or dairy products, while soy and legumes appeared to be slightly protective. The study also found that replacing one serving of red meat with another protein reduced the risk of kidney failure up to 62 percent for poultry.
