People who ate the most fiber were less likely to die of any cause during a recent study of nearly one million people.
The finding might be explained by fiber’s potential to lower the risk of chronic diseases including heart disease, stroke, diabetes and several types of cancer, researchers say.
Individuals should be encouraged to increase their dietary fiber intake "to potentially decrease the risk of premature death,” Yang Yang, of the Shanghai Cancer Institute in China, and colleagues write in the American Journal of Epidemiology.
They pooled data from 17 previous studies that tracked 982,411 men and women, mostly in Europe and the U.S., and recorded about 67,000 deaths.
Yang’s team divided participants into five groups based on their daily fiber intake. Those in the top fifth, who ate the greatest amount of fiber daily, were 16 percent less likely to die than those in the bottom fifth, who consumed the least amount of fiber.
In addition, eight studies showed a 10 percent drop in risk for any cause of death with each 10-gram per day increase in fiber intake.
The U.S. Department of Agriculture recommends that adults consume 14 grams of fiber in every 1,000 calories they take in, the authors point out. That translates to approximately 25 grams a day for women and 38 grams daily for men.
“On average, intakes of dietary fiber in the U.S. and other economically developed countries are much lower than recommended goals – in the U.S., about half of what is advised,” said Victoria Burley, a nutrition researcher at the University of Leeds in the UK, who was not involved in the study.
These study results are "very much in line with earlier published meta-analyses of the relationship between dietary fiber and risk of major chronic diseases such as cardiovascular disease, and cancers,” Burley told Reuters Health in an email.
