High-fiber diet may reduce dementia risk

New research finds that high levels of dietary fiber are associated with a lower risk of dement.

Researchers at the University of Tsukuba in Japan have found that high levels of dietary fiber, especially soluble fiber, are associated with a lower risk of dement.

We are often told that we should eat more fib.

"Dementia is a devastating disease that often requires long-term care," said the study's lead author, Professor Kazumasa Yamagis.

Participants completed surveys assessing their dietary consumption between 1985 and 199 They were generally healthy and aged between 40 and 6 Researchers followed them from 1999 to 2020 and recorded whether they developed dementia requiring ca.

The scientists divided the data into four groups based on the fiber content of the diets of 3,739 adul.

The team also looked at whether there are differences between the two main types of fiber: soluble and insolub.

The research team has a few theories about the link between dietary fiber and dementia ri.

"The mechanism is currently unknown, but may involve interactions between the gut and the brain," said Pr.

In many countries today, such as the United States and Australia, many people consume less fiber than nutritionists recomme.
