(Health Secrets) Everyone loves a steak sizzling on the barbeque, but overcooked or charred meat could double your risk of getting bladder cancer, according to a Texas based study. The study supports the belief that burnt food can be carcinogenic, as well as the idea that eating too much red meat can increase the risk of developing cancer. It also indicates that genetic factors play a part in these trends.

What does the study show?
The study, undertaken by the University of Texas over 12 years, looked at over 1700 subjects. It was discovered that people who regularly ate well done or overcooked meat were twice as likely to develop bladder cancer as those who preferred to eat their meat rare.
The results also showed that people eating a lot of overcooked red meat such as pork chops, steak or bacon were at a higher risk of developing bladder cancer than people consuming white meat, although chicken and fish still increase cancer risk when they are fried.
Professor Xifeng Wu, lead author of the study, explained, “These results strongly support what we suspected – people who eat a lot of red meat, particularly well-done red meat, such as fried or barbecued, seem to have a higher likelihood of bladder cancer.”
During the study, the DNA of each subject was also analyzed to identify different ways of metabolizing the overcooked meat. The results suggest that the presence of certain genes made subjects up to five times more likely to develop bladder cancer when they ate a lot of overcooked red meat.
