Explains the concept of the gut-brain axis, and its implications for health and disease. Describes how microbes and their metabolites communicate with the body and the brain. Explains how the microbiome-gut-brain axis influences the development of neurodegenerative, neuropsychiatric, and neurodevelopmental disorders. Describes how microbial metabolites regulate immune and metabolic pathways in the body, and how this may impact risk of allergies, autoimmune diseases, obesity and diabetes. Explains how the ecology of the oral microbiome impacts both gut and systemic health; discusses implications for modern-day oral healthcare. Lists potential microbial and gut health disruptors, as well as therapeutic strategies to improve gut and brain health (to become “ecosystem engineers”). Describes ways in which the highly complex gut-brain scientific research has been oversold and misinterpreted by the lay press. Identifies red flags of “pseudoscience” to become a healthy skeptic. Describes how the information in this course can be utilized to improve patient care and patient outcomes.

Describes how perception, thinking, emotions, and memory combine to produce cognitive appraisals and behavior. Outlines the causes, components, and management of psychological stress. Defines resilience and explain the factors that compose the ability to “bounce back” from stressful events. Lists the major components of the positive-psychology approach to increasing life satisfaction. Identifies the elements of happiness and optimism and how to apply them to increase well-being. Describes how the information in this course can be utilized to improve patient care and patient outcomes. Describes, for this course, the implications for dentistry, mental health, nursing, and other healthcare professions.

Explains the complex nature of body fat and why both too much and too little are deleterious to health. Describes how genes, eating behavior, macronutrients, physiology, microorganisms, and the environment interact to produce obesity. Outlines how the food industry’s production of hyperpalatable foods fuels sweet, fat, and salt addiction and the obesity epidemic. Identifies the most effective diets that could produce long-lasting results in weight loss. Explains strategies for maintaining successful weight loss, managing food cravings, and treating emotional overeating. Identifies the relative effectiveness of diet, exercise, medications, and surgery in maintaining weight loss. Describes how the information in this course can be utilized to improve patient care and patient outcomes. Describes, for this course, the implications for dentistry, mental health, nursing, and other healthcare professions.
