We all know that dietary fiber is an important element in a balanced diet but new research has broken down the mechanism by which it can delay brain aging or more specifically... age related brain inflammation. In this fascinating article from medicalnewstoday.com the process is explained.
If all the studies that urge people to consume a diet rich in fruits, vegetables, and whole grains for a healthy life haven't convinced you yet to add more broccoli to your plate, perhaps this latest research will.
Eating fiber-rich foods — such as broccoli, nuts, oats, beans, and whole-grain bread — might help delay brain aging by triggering the production of a short-chain fatty acid that has anti-inflammatory properties.
Here's the technical part. Inflammation of the microglia that occurs with age is what causes the cognitive decline. If eating more fiber can help prevent this then its something we should all be doing to prevent premature brain aging.
As Matt and colleagues explain in their study paper, microglia — a major type of immune cell in the brain — tend to become hyperactive and chronically inflamed with age. This inflammation of the microglia is one of the main causes of memory and cognitive decline in old age.
Previous research has shown that a drug form of butyrate, which is a short-chain fatty acid that is produced in the colon when bacteria ferment fiber in the gut, can improve memory and reduce inflammation in mice.
This remarkable research would certainly indicate that we should be adding more fiber to our diets for many reasons, not only to prevent brain aging. I'm certainly going to. Hit the button below to read the full post.
