Study Shows Eating Fiber Helps Improve Inflammation Related To Gum Disease

At some point we've likely all been scolded by a dentist to cool it on the sugar intake (candy, soda, fruit juices, etc.). Because too much sugar equals cavities, right? Yep. So what you eat clearly plays a role in oral health. As it turns out, eating more fiber may protect your gums. 

A systematic review and meta-analysis published in the journal Nutrients was one of the first to take a comprehensive look at all the studies to date in humans on fiber intake and periodontal disease1 (aka gum disease). 

Gum disease results from infection or inflammation of the gums and bones that surround and support the teeth. It's actually one of the top six chronic diseases across the globe. 

The health of your teeth is highly influenced by lifestyle, and this review sheds much-needed light on how what you eat influences an all too common (and preventable) chronic condition. 

A total of six studies were included in this larger analysis. Five of them were experiments where people were given more fiber by the researchers to eat, and one study when people were told to eat a high-fiber diet for one or two months. 

Researchers wanted to see if there was a connection between fiber intake and measures of inflammation related to gum disease. 

And there sure was. 

Fiber is unfortunately lacking in most Americans' diets. Only 5% of people meet the recommended daily amount of fiber4 (21 to 25 grams daily for women and 30 to 38 grams for men). 

So there's a lot of room for improvement. To help put that into context, here's how much fiber you can expect from some of the most fiber-rich foods out there.

It's exciting to see more research on the connection between oral health and nutrition because it's about time for more granular recommendations than eating less sugar. This study offers one of the most comprehensive looks yet at the role of fiber in helping to alleviate gum-related inflammation.
