You can’t change your genes, but you can influence the environment your body’s microbes live in. So, what does your microbiome have to do with digestion, immunity, energy, mental clarity, and even the conversations you have with patients? In this episode, Kirk Behrendt brings back Dr. Uche Odiatu, dentist, health educator, and speaker, to explain why the microbiome matters and how everyday choices like fiber intake, fermented foods, movement, sleep, and antibiotic use can affect it. You’ll also learn how dental professionals can expand the conversation beyond teeth and smiles to help patients understand the connection between chewing, nutrition, saliva, and whole-body health. To start making more mindful choices for your microbiome, listen to Episode 1119 of The Best Practices Show! Main Takeaways: The microbiome is a large community of microorganisms that influences digestion, immunity, metabolism, cravings, and other functions throughout the body. Fiber, fermented foods, and a consistent light-dark cycle can help support a healthier environment for beneficial bacteria. Physical activity is associated with greater diversity in the gut microbiome, which Dr. Odiatu connects with healthier aging and metabolic function. The gut and brain communicate extensively, which is one reason the microbiome is being studied in relation to mood, anxiety, mental clarity, and emotional well-being.Dentists can make function more meaningful to patients by explaining how better chewing can support food breakdown, nutrient intake, and everyday quality of life. Saliva supports speech, chewing, digestion, and immune defense, making dry mouth an important health concern for dental teams to recognize. Antibiotics are important when medically necessary, but unnecessary or excessive use can disrupt beneficial bacteria and contribute to antibiotic resistance.
