The correlation between food consumption and oral health is becoming more apparent as modern dental diseases are connected with food, lifestyle and environmental choices. In this episode of The Biofilm Factor, Dr. Ryan Nolan talks with Dr. Steven Lin, author of bestselling book The Dental Diet. They discuss the societal shift towards processed food, especially the increase in added sugars, in the past 200 to 300 years. This has resulted in higher instances of sleep apnea, asthma, immune system deficiencies and more. Dr. Lin focuses on recognizing how an individual’s environment influences how his or her genetics are expressed. With this information, Dr. Steven Lin promotes a shift in approach towards proper nutrition and functional dentistry, bridging the gap between oral health and the rest of the body. Food is medicine and we have been feeding our mouths the wrong things for too long.
