Omega-3 fatty acids, present in foods like fish and walnuts, are considered "healthy fats," and have been associated with brain health, improved immune system function, and reduced risk of cancer, heart disease, and depression.
And a new study has determined consuming omega-3 fatty acids helps lower the risk of periodontitis, which is a form of gum disease causing inflammation around the teeth, and bone loss due to bacteria buildup in the mouth.
The United States Centers for Disease Control and Prevention (CDC) recommends replacing harmful fats, such as saturated fats, with omega-3 fats.
Published in the Journal of the American Dietetic Association, researchers found study participants (9,000 adults taking part in a national health survey) with intermediate or high intake of docosahexaenoic acid (DHA), a form of omega-3 fatty acids, were less likely to develop periodontitis.
Even after accounting for other factors, such as age, sex, and calorie intake, study participants in the top third of DHA consumption had a 22% lower risk of gum disease, compared to people getting the lowest amount of DHA.
But the scientists will not confirm that omega-3s have "true protective" effects against gum disease, and still recommend going to your dentist for regular cleanings to prevent gum problems.
Maintaining proper dental hygiene is an important part of preventing heart trouble. Previous research indicates plaque in the mouth raises risk of cardiovascular disease. The American Dental Association recommends regular checkups with your dentist to prevent and identify potential mouth risks.
Other food sources of omega-3s include flaxseed, tiny shrimp called krill, and eggs laid by chickens fed a diet of greens and insects.
