A recent study published in the journal BMC Medicine showed that those who ate more fiber-rich whole grain foods may live longer than those who don’t eat them very often. Researchers looked at adults aged 50 to 71 over about 10 to 15 years. They tracked the subjects’ health status and fiber consumption. It was found that those who ate the most fiber had a two-tenths lower risk of death during the study, as well as lower risks for cancer and diabetes.
