A comprehensive study unveiled last week shows people regularly eating red meat, such as beef, are at a higher risk of developing colon cancer than those with a more balanced diet.
A long term study published in the Journal of the American Medical Association tracked the eating habits of 150-thousand people between 1982 and 1992. From the time the data were collected until the study's conclusion a decade later, researchers found that those who consumed the most red meat had a 30 to 40 percent greater risk of colon and rectal cancer than those whose diets were rich in fish and chicken. Study co-author Margie McCullough of the American Cancer Society notes the research confirms the results of many other smaller studies.
In the same issue of the Journal, researchers report a diet rich in fruit and vegetables does not appear to protect women against breast cancer. The results seem to contradict other scientific evidence, as well as a commonly held belief, that fruits and vegetables are protective against cancer.Despite the latest findings, Ms. McCullough says women shouldn't stop eating vegetables.
But she says there is evidence to show obesity may be a factor in breast cancer risk. Eating fruits and vegetables, she says, helps women to keep their weight down.
