Does Dairy Do a Colon Good?
Eating dairy foods may lower the risk of colon cancer.
WebMD Feature Got milk? If the results of a recent study hold true, you might consider reaching for a tall glass of the one percent. A grain of salt might go well with your beverage, too.
The study -- published in the September 23 issue of The Journal of the American Medical Association and discussed at the annual meeting of the American Dietetic Association in October -- found that people who ate a diet rich in low-fat dairy products may have fewer abnormal, pre-cancerous cell growths in the colon than people on conventional diets.
This may be encouraging news for people fighting colorectal cancer, which claims more than 56,000 American lives every year, according to the American Cancer Society. About 130,000 new cases are diagnosed every year.
The Study's Results
Peter Holt, MD, of Columbia University conducted the research at St. Luke's-Roosevelt Hospital Center in New York. He examined 70 men and women who had abnormal cells that were growing unusually quickly in their colons -- a marker for colorectal cancer risk.
While one group stayed on a conventional diet, another group consumed a diet including enough low-fat dairy foods to provide 1,500 milligrams of calcium per day. The researchers then examined the participants' colons after six months and a year. On the average, people on the high-dairy diet had fewer abnormal cells, and those cells' growth had slowed. People who remained on a conventional diet continued to experience abnormal cell growth in their colons.
