Consumption of high-fiber fruits and bread may be one way to prolong life without developing chronic diseases, a new Australian study suggests.
The researchers followed about 1,600 adults, aged 49 or older, who had no history of cancer, stroke or cardiovascular disease for at least a decade.
Participants also had to answer a survey related to their fiber intake and eating habits.
At the end of the study, about 250 people had achieved what scientists call "successful aging," meaning they had not developed diseases such as cancer or heart disease.
In addition, they had no depression, disability, cognitive impairment, diabetes or other health problems.
People who ate the most fiber were 79 percent more likely to age healthily than participants who consumed significantly less fiber, the study found.
"Fiber can limit inflammation in the body, which is a very important factor in many of these diseases. In this way, they have a protective effect on the body and health, and protect against disease, "explains the lead author of the study Bamini Gopinat of the University of Sydney, to Reuters.
Two other studies also show that high-fiber whole grains can reduce the risk of developing cardiovascular disease and cancer.
Researchers have found that fiber consumed through fruits, whole grain breads and cereals such as oats have been linked to good health as we age.
This suggests that the impact of fiber on aging and health may vary depending on dietary sources.
