Can a Plant-Based Diet Improve Oral Health?

Dental hygienists can play a role in reducing the morbidity and mortality associated with poor nutrition and other lifestyle habits. Increasing evidence of the relationship between physical and oral health emphasizes the urgency of increasing the public’s understanding of the effects of poor nutrition. Early data from the COVID-19 pandemic show that those with chronic diseases, such as diabetes, obesity, and cardiovascular disease (CVD), are more severely affected by the virus. The mechanisms behind this are not fully understood, but a new study posits that the health of the gut microbiome plays a crucial role. The microbiome is integral to immune function, and diet is important in cultivating healthy gut microbiomes. Eating a high-fiber, plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes encourages the growth of a healthy microbiome, improving immunity and overall health.
