The study, published in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences, found that people who ate more fiber from cereals, breads, and fruits actually experienced a lower risk of age-related diseases and disability, like high blood pressure and even cognitive problems.
In the study, the researchers analyzed 1,600 adults who were over the age of 50 who were involved in the Blue Mountains Eye Study, which gathered data on systemic diseases and aging. The researchers focused primarily on the link between carbohydrate intake and aging — and found that people who ate more fiber were more likely to age successfully. That meant they were less likely to suffer from disability, depressive symptoms, cognitive impairment, respiratory diseases, and other chronic diseases like cancer, heart problems, stroke, and diabetes. In past research, a high-fiber diet has been shown to maintain gut bacteria and lower a woman’s breast cancer risk.
However, the study may have a few holes. For example, most of the participants examined had low sugar intake to begin with, which means their successful aging may have been impacted more by the low sugar in their diets, or proper nutrition beyond simply fiber.
