New Fiber Study

It is common today for people to eat a high fiber diet to protect against colorectal cancer. Now a new, huge study may contradict that theory.

The study in JAMA, the Journal of the American Medical Association, actually included thirteen different studies within it, tracking the health and fiber-eating habits of more than 725,000 people for up to twenty years. About 8,000 of those people developed colorectal cancer, but the study found that fiber did not affect the colon cancer risk after all.

"We found that people who ate higher amounts of fiber had the same risk of developing colorectal cancer as individuals who ate lower amounts of fiber," says Stephanie Smith-Warner Ph.D. at Harvard School of Public Health.

Here is where the fine line comes in, the study says fiber may not affect colorectal cancer, but there was some evidence that a high fiber diet did lower the risk of rectal cancer a little and fiber has been shown to help reduce heart disease and the risk of diabetes. So, it is still considered healthy and even good preventive medicine, in some other ways.
