you lovers of red meat? If so, it seems from now on you should be more careful eating this one. Previously, the study claims red meat consumption and colon cancer triggers breast. However, recent studies say, the consumption of red meat excess can trigger the development of kidney cancer.

The researchers found that middle-aged adults who ate the most red meat by 19 percent more likely to be diagnosed with kidney cancer, than those who ate the least. High intake of chemicals found in roasted or grilled meats were also associated with an increased risk of this disease. Reports the American Journal of Clinical Nutrition.

"Red meat is an important source for iron (and) and proteins," said Dr. Mohammed El-Faramawi, an epidemiologist from the University of North Texas Health Science Center at Fort Worth, who has studied diet and risk of kidney cancer.

"You do not have to stop eating red meat just because it has something to do with kidney cancer. Conversely, eating red meat with a limited number and follow the dietary recommendations is a good idea," he explained.

To replace the consumption of processed meat which has a high fat content, can be tricked by eating more lean meats and poultry, seafood and nuts.

El Framawi added, eating red meat in large numbers does not always lead to kidney cancer, but rather on increasing the number of risk of health problems such as the buildup of plaque in arteries.

The study included 500 000 U.S. adults aged 50 years and over. Things were surveyed about their dietary habits, including consumption of meat. Then, respondents were followed for about nine years to track the cancer diagnosis. During that time, about 1,800 of them, less than half a percent-were diagnosed with kidney cancer.

On average, men in the study ate two or three ounces of red meat per day. Participants with the highest consumption of red meat, which is about four ounces per day, 19 percent more likely to be diagnosed with kidney cancer than those who ate the smallest amount, less than one ounce per day.

In his research, researchers also have take into account other aspects related to diet (eating) and lifestyle that can affect cancer risk such as age, race, fruits and vegetables, smoking, alcohol consumption, and other medical conditions including high blood pressure and diabetes.

However, this study does not directly indicate that consumption of red meat, or cook in a certain way, will cause kidney cancer. Researchers say, relationship between red meat and cancer is more strongly related to papillary cancer, but no apparent effect for kidney cancer.
