A new study claims that people who reported eating a diet rich in cereal fiber lived longer than those who didn't.

The survey out of the Harvard School of Public Health found that high fiber cereal had a 34 percent lower risk of death from diabetes and a 15 percent reduced risk of death from cancer. People who ate a lot of whole grains and dietary fiber had a 17 percent lower risk of all-cause mortality.

Cereal fiber, the study authors conclude, is one "potentially protective component" of a healthy, premature death-preventing diet.

The study was published in the latest issue of BMC Medicine and included more than 566,000 AARP members ages 50 to 71 from two large cities. It excluded people who reported extreme-energy intake, which is common, which is common, since scientists believe these survey takers are not totally accurate with what they report. That left them with more than 367,000 people.
