Eat Meat Seared, Not Charred Well-Done Meats Increase Bladder Cancer Risk

By Denny Watkins

A summer cookout can raise your risk of bladder cancer if you like your meat well done, say University of Texas researchers.

In the study, scientists used a questionnaire to gather information about the eating habits of 884 patients with bladder cancer and 878 cancer-free people. The researchers discovered that people who ate meat cooked well-done had a 94 percent higher risk of developing bladder cancer, while people who ate meat cooked medium-well saw a 46 percent higher risk when compared to eating rare meat.

"Cooking meat at high temperatures and for longer periods of the time creates carcinogens," explains study author Dr. Jie Lin, assistant professor of epidemiology at the University of Texas M.D. Anderson Cancer Center.

The carcinogens in well-done meat are called heterocyclic amines, or HCAs. After the compounds enter your body, they interact with digestive enzymes and take a form that can react with DNA. When enough reactive HCAs have accumulated in a cell, they create errors in the DNA that leads to runaway cell growth and cancer.

High amounts of HCA consumption have been linked in other studies to higher risk of stomach, breast, pancreatic and colorectal cancer.

The University of Texas study further determined a genetic component to the bladder cancer-HCA link. Patients with certain genes can better eliminate HCAs from their body, leading to a marked drop in their risk of developing cancer. The researchers hope to eventually develop a genetic test that can determine whether people can safely eat a well-done steak or pork barbeque.

The study also found a high correlation between eating red meat, including pork and beef, and developing bladder cancer, although eating chicken and fish also elevated the risk of the disease.

"Most people cook red meat at high temperatures, which is what creates the harmful HCAs," says study co-author Dr. Xifeng Wu. "If you eat fried fish or fried chicken, you will also see a higher risk of cancer."

Scientists consider food cooked above 392 degrees Fahrenheit to be "high-temperature" cooking. Meat that has been boiled or poached in boiling water at 212 degrees F produces almost no harmful HCAs.

Unfortunately, undercooking pork or chicken can increase your risk of getting sick from food-borne pathogens such as salmonella or trichinella. But a tuna or beef steak seared quickly, the fresh raw fish in sushi or fish prepared ceviche style in acidic citrus juice are safer to consume. However, be aware that there's always a danger of food-borne illness whenever you consume raw or undercooked meat or fish.

Busting Cancer Myths: Acidic Foods and Cancer Risks

The Claim:  Acidic foods can alter the body’s pH balance and promote cancer.

The Facts:  That unsubstantiated theory is based upon lab studies suggesting that cancer cells thrive in an acidic (low pH) environment, but cannot survive the alkaline (high pH) surroundings.  While these findings are accurate, they apply only to cells in an isolated lab setting.  Altering the cell environment of the human body to create a less-acidic environment is virtually impossible.

While proponents of this myth argue that avoiding certain foods and others can change the body’s pH level, these claims stand in stark contrast to everything we know about the chemistry of the human body.  Acid/base balance is tightly regulated by several mechanisms, among them kidney and respiratory functions.  Even slight changes to the body’s pH are life-threatening.  Patients with kidney disease and pulmonary dysfunction, for example, often rely on dialysis machines and mechanical ventilators to avoid even the smallest disruption of the acid/base balance.

In addition, home test kits that measure the pH of urine do not relay information about the body’s pH level.  It’s true that foods, drinks, and supplements will affect the acidity or alkalinity of urine, but only the urine is affected.  In fact, excess acid or base is excreted in the urine to help maintain  proper pH balance in the body.

What is consumed can and often does have a profound effect on cancer risk, but the acidity or alkalinity of foods is not important.  Instead, focus on healthy nutrition and making healthy dietary choices, that can ultimately affect our risk.  Eat wide varieties of vegetable, fruits, whole grains, and beans;limit consumption of read meat, processes meats; and consume alcoholic beverages, in moderation, if at all.

With the ease and availability of the Internet, superhighway, or whatever you wish to name it, many myths regarding cancer are easily spread to consumers and it can be difficult to expose fact from fiction.  A brochure by the American Institute for Cancer Research title “Everything Doesn’t Cause Cancer,” is a great way to dispel some myths or concerns about our own risk of cancer.
