You are told to brush, ﬂoss, and rinse every day, but has your dentist told you to consume more Omega 3 fatty acids lately? He should, according the latest study from Japan comparing levels of omega-3 fatty acids and the prevalence of dental diseases. “People with low DHA intake had an approximately 1.5 times higher incidence rate ratio of periodontal disease progression,” wrote the researchers. Omega-3 fatty acids of marine and plant origin were found to have strong anti-bacterial activity against a range of oral pathogens, which may be related to the anti-inﬂammatory eﬀects of omega-3 fatty acids. “In periodontal diseases, bacteria trigger inﬂammatory host responses that cause destruction of the alveolar bone and periodontal connective tissue,” explained the researchers. The Mediterranean Diet features ingredients rich in omega-3 fatty acids such as ﬁsh, nuts, legumes and vegetables. This pattern of eating is already known to protect against certain kinds of cancer, Alzheimer’s, and diabetes. Now there is one more reason to try it. (Related article).
