High-fiber diets are known to have health benefits. Now a new review in the British Medical Journal finds increasing fiber, particularly from cereal and whole grains, helps prevent colorectal cancer.

But the analysis of 25 previous studies found that fruit and vegetables did not reduce risk.

Consuming 90 grams a day of whole grains was associated with about a 20 percent lower risk.

Some doctors are now calling for more detailed research on how much and exactly what type of fiber we should be eating each day.
