A new study suggests that what you eat affects your risk of gum disease and maybe your overall health. In a recent study published in the journal Scientific Reports, researchers at the University at Buffalo studied over 1,200 postmenopausal women to see whether carbs, and specifically sugar, affected the bacteria in the mouth and under the gums. They observed that higher intake of sugary foods, soft drinks, and breads affected the oral microbiome in a way that might predispose someone to periodontal disease. Further research will be needed to see if these refined carbohydrate foods affect other health outcomes, like cardiovascular disease.
