Red Meat Eaters Have More Kidney Cancer

Individuals who eat red meat are reported to suffer from a higher risk of some types of kidney cancer.

According to U.S. researchers middle-aged adults who ate the most red meat were almost one fifth (19%) more likely to be diagnosed with kidney cancer than those who ate the least. The scientists also noted that the increased intake of chemicals found in barbecued or grilled meats was also linked to increased risk of the disease.

“Cancer is increasingly a critical illness impacting millions of American adults,” explains Jesse Slome, executive director of the American Association for Long-Term Care Insurance. “U.S. guidelines for better health call for limiting high-fat foods including processed meat, and instead eating more lean meat and poultry, seafood and nuts.”

Researchers noted that previous studies examined links between red meat and kidney cancer had arrived at mixed conclusion. Researchers at the National Cancer Institute in Rockville used data from a study of close to 500,000 U.S. adults age 50 and older, which were surveyed on their dietary habits, including meat consumption. The researchers followed the study group for an average of nine years to track any new cancer diagnoses.

On average, men in the study ate two or three ounces of red meat per day, compared to one or two ounces among women.

During the study time period some 1,800 of the participants or less than half a percent were diagnosed with kidney cancer. Those with the highest consumption of red meat were 19 percent more likely to be diagnosed with kidney cancer than those who ate the smallest amount. The highest consumption was about four ounces per day and the lowest was less than one ounce per day.

People who ate the most well-done grilled and barbecued meat and therefore had the highest exposure to carcinogenic chemicals that come out of the cooking process also had an extra risk of kidney cancer compared to those who didn’t cook much meat that way.

“More Americans are following healthier plans with the desire of living a long life,” Slome explains. “If you live into your 80s or beyond, the likelihood you will need long term care is vastly increased but you need to start preparing for this in your 50s and early 60s when the most planning options are still available to you.”
