teethA recent study published in the journal Nature Genetics has shed light on trends in oral health over time as our diet has evolved to include more carbohydrates/sugars. Alan Cooper and his fellow researchers evaluated 34 prehistoric sets of teeth, concluding that teeth were much healthier when we were hunters, primarily eating meat, nuts and vegetables. As processed foods and sugars became introduced into our diet, the bacteria that lives in our mouths changed, allowing for more opportunistic infections, despite flossing and brushing. Have you ever considered the impact your diet has on your oral hygiene?
