Diet and Cancer Study

 Millions of people are still trying to stick with their new year's resolutions. Topping the list for a many is eating healthier. For most, the goal of eating better is to lose weight. But some may also want to consider whether their diet is putting them at risk for cancer.

Each year, 200,000 American men are diagnosed with prostate cancer. Only about 10 percent as many Japanese develop it. Preventive Medicine Specialist Laurence Kolonel, M.D., Ph.D., has an idea why. “We concluded that the likeliest area to focus on was diet”.

A study found when the Japanese move to Hawaii and encounter a Western diet, their cancer rate rises. Offspring show even higher rates. Now Dr. Kolonel, of University of Hawaii in Honolulu, is looking even closer at the issue “to see which components of the diet either increase risk for cancer and which components of the diet may actually protect against cancer”.

Diet and Cancer StudyIn his study, 215,000 participants will have their diets tracked to figure out what pattern of eating leads to good health.

Dean Ornish, M.D., already has one idea. “It’s not only what you exclude from your diet, but also what you include in your diet that’s important,” says Dr. Ornish, who is the founder of the Non-Profit Preventative Medicine Research Institute at the University of California, San Francisco.

Dr. Ornish encourages eating a diet like the Japanese, low in fat and high in fruits, vegetables, grains, beans and soy. He says, “What we found was that after three months, PSA levels as a marker for prostate cancer, were essentially unchanged in the comparison group, but they went down significantly in the group that made comprehensive changes in diet and lifestyle.”

By studying the blood and urine of participants, Dr. Kolonel says he’ll be able to look at biochemical markers to get a better idea of what happens to the food after it’s absorbed into the bloodstream.
