Gut microbiota, nutrition, and mental health.

The human brain remains one of the greatest challenges for modern medicine, yet it is one of the most integral and sometimes overlooked aspects of medicine. The human brain consists of roughly 100 billion neurons, 100 trillion neuronal connections and consumes about 20-25% of the body's energy. Emerging evidence highlights that insufficient or inadequate nutrition is linked to an increased risk of brain health, mental health, and psychological functioning compromise. A core component of this relationship includes the intricate dynamics of the brain-gut-microbiota (BGM) system, which is a progressively recognized factor in the sphere of mental/brain health. The bidirectional relationship between the brain, gut, and gut microbiota along the BGM system not only affects nutrient absorption and utilization, but also it exerts substantial influence on cognitive processes, mood regulation, neuroplasticity, and other indices of mental/brain health. Neuroplasticity is the brain's capacity for adaptation and neural regeneration in response to stimuli. Understanding neuroplasticity and considering interventions that enhance the remarkable ability of the brain to change through experience constitutes a burgeoning area of research that has substantial potential for improving well-being, resilience, and overall brain health through optimal nutrition and lifestyle interventions. The nexus of lifestyle interventions and both academic and clinical perspectives of nutritional neuroscience emerges as a potent tool to enhance patient outcomes, proactively mitigate mental/brain health challenges, and improve the management and treatment of existing mental/brain health conditions by championing health-promoting dietary patterns, rectifying nutritional deficiencies, and seamlessly integrating nutrition-centered strategies into clinical care.

Primary Care at the Intersection of Lifestyle Interventions and Unhealthy Substance Use.

Primary care physicians are well-positioned to integrate lifestyle interventions into the management of patients with unhealthy substance use, who may also have mental and physical chronic health comorbidities. However, the COVID-19 pandemic exacerbated the U.S.'s poor state of health, revealing that its current approach to chronic disease management is neither effective nor sustainable. Today's full spectrum comprehensive care model requires an expanded toolkit. Lifestyle interventions broaden current treatment approaches and may enhance Addiction Medicine care. Primary care providers have the potential to have the greatest impact on unhealthy substance use care because they are experts in chronic disease management and their frontline accessibility minimizes healthcare barriers. Individuals with unhealthy substance use are at an increased risk of chronic physical conditions. Incorporating lifestyle interventions with unhealthy substance use care at every level of medicine, from medical school through practice, normalizes both as part of the standard care of medicine and will drive evidence-based best practices to support patients through prevention, treatment, and reversal of chronic diseases.

Personal and Planetary Health-The Connection With Dietary Choices.

This Viewpoint offers strategies to help shift to plant-based diets to reduce climate change and promote individual health by encouraging patients, incorporating the environmental impact of food choices in national dietary guidelines, and adding plant-based nutrition training in medical schools.

Applying Psychiatry and Psychology Principles to Lifestyle Approaches for Mental and Behavioral Health.

Research suggests that mental health symptoms and disorders are historically underdiagnosed and undertreated, in part due to the siloed nature of medicine. Yet, approximately 50 million American adults experience a mental health disorder. As the field of lifestyle medicine continues to emerge and grow, there is an important opportunity to address mental health from a lifestyle medicine perspective, as well as to ensure that lifestyle medicine can be utilized for all patients, including those with mental health conditions. To effectively address mental health, the field of lifestyle medicine would benefit from understanding and leveraging the decades of science and practice from the fields of psychiatry and psychology, as well as the expertise of psychiatrists and psychologists who are familiar with the science and trained in lifestyle medicine. Incorporating empirical literature from other areas, utilizing well-established conceptual frameworks, and addressing the overlap between lifestyle medicine and mental health early in, and throughout, training and education, are important steps to move toward addressing mental and behavioral health with a lifestyle medicine approach.

Incorporating Mental Health Into Lifestyle Medicine.

The evidence-based interconnection between mental health with lifestyle medicine practice is discussed. The extent to which physical health, and mental and behavioral health overlap are significant, and their interaction is seen in many ways. These bidirectional influences form a continuous thread through all lifestyle medicine pillars. The intersection of mental health and lifestyle should be considered and applied to provide optimal evidence-based lifestyle medicine for all patient populations who will benefit from the specific attention to diet, physical activity, relationships, stress, sleep, and substance use. Lifestyle medicine can be utilized to directly address and treat a range of mental health symptoms and disorders, and physical illnesses. In addition, behavior change skills and addressing the psychological factors contributing to barriers are crucial to helping patients reach their lifestyle medicine goals. Approaches to practice that attend to, and address, mental and behavioral health are relevant to and necessary for all types of providers who work within the lifestyle medicine framework.

Mental Health in Lifestyle Medicine: A Call to Action.

Mental health symptoms are pervasive, with 1 in 5 American adults experiencing a mental disorder. Poor mental health is associated with a significant global cost burden, from disability to economic impacts. The field of lifestyle medicine, which emphasizes the role of lifestyle factors in the onset and treatment of disease and well-being, is well suited to address mental health. More recently, there has been attention to the need to incorporate mental health into the field of lifestyle medicine and to attend to the bidirectional role of mental health and lifestyle. Thus, there is a critical opportunity for the field of lifestyle medicine to incorporate mental health into each of the foundational pillars (diet, exercise, substance use, psychological well-being/stress, relationships, sleep) while also specifically targeting lifestyle interventions for populations with mental disorders. The current article provides a framework for the role of mental health within lifestyle medicine by addressing the scope of the problem, clarification regarding mental health, and areas of practice (ie, psychiatry), and providing an overview of the relevant mental health literature for each pillar. This article serves as a call to action to explicitly address and include mental health within all aspects of lifestyle medicine research and practice.

Physician Burnout: A Lifestyle Medicine Perspective.

Physician burnout, as described in North America, is a multidimensional work-related syndrome that includes emotional exhaustion, depersonalization, and a low sense of accomplishment from work. More than 50% of physicians were reporting symptoms of burnout prior to the COVID-19 pandemic. This silent epidemic of burnout is bound to become less silent as the pandemic continues. Lifestyle medicine is an evidence-based discipline that describes how daily habits and health practices can affect overall health and well-being of individuals. Lifestyle Medicine can potentially play a significant role in preventing and ameliorating physician burnout. This article explores the burnout process, including the historical context, international definitions, symptoms, and imprecision of the clinical diagnosis. The systemic etiological issues are discussed, and the psychological underpinnings are explored, including physicians' personal vulnerabilities contributing to burnout. The stress response and lifestyle medicine's role in healthy coping are described. A prevention model for risk factor reduction is proposed, focusing on primordial, primary, secondary, and tertiary prevention. Lifestyle medicine clinicians' role in prevention, treatment, and advocacy to ameliorate the potential for burnout is discussed along with specific recommendations.

MPRO: A Professionalism Curriculum to Enhance the Professional Identity Formation of University Premedical Students.

Limited opportunities exist for university premedical students to gain exposure to the realities of clinical practice through physician shadowing or through a formal curriculum. Medical Professionalism and Observership utilizes didactics, reflective writing, small- and large- group discussions, and clinical observerships to enhance the process of professional identity formation during a critical developmental window of late- adolescence. The pilot semester included a sample of 135 students, all in their sophomore, junior, or senior years of study at Rice University. Students were selected through an application process and paired with physicians at Houston Methodist Hospital based on specialty preference and availability. Students were required to participate in biweekly lectures and discussions and to submit a weekly reflection on topics discussed in the course and their shadowing experiences. Student evaluations were administered to survey changes in students' knowledge and perceptions of the curriculum. Selected reflections were read for evidence of professional identity formation. Lectures increased students' exposure to core competencies within the medical profession and influenced their desire to become physicians. Reflective writings demonstrated integration of these core competencies into the professional identity of students. Structured reflection and didactics, when coupled with physician shadowing, appear to promote integration of the values, beliefs, and attitudes of medical professionalism. Future studies should seek to demonstrate how such a curriculum affects professional identity formation through established measures, and to assess whether such a curriculum may influence students' preparedness for medical training and practice as they progress along their careers.

Laying an Early Foundation: Lifestyle Medicine Pre-Professional Education (LMPP) Member Interest Group.

Just as lifestyle medicine is the necessary foundation for true health care reform, lifestyle medicine competencies should be the foundation for health education. Although lifestyle medicine education may benefit a health professional at any stage in their education or career, evidence-based undergraduate lifestyle medicine education for future health professionals shifts the perspective of health and health care delivery. Educating health preprofessionals in associate, bachelor's, master's, and other preprofessional healthcare training programs is of paramount importance due to the interdisciplinary nature of lifestyle medicine. To accomplish this, American College of Lifestyle Medicine (ACLM) members can work collaboratively through committees, projects, and working groups-becoming leadership champions of change. An ACLM Pre-Professional Member Interest Group (LMPP) was created in 2018. LMPP has been working to build a national collaborative effort to amass, create, and distribute resources for educators in this pre-professional arena. Educating college students planning to become professionals outside the medical sphere, for example, lawyers, business people, artists, and engineers, will also benefit the field by introducing the power of nutrition, exercise, sleep, social connection, and stress resiliency during this formative state of career development. Pre-professional educational programs provide learners the opportunity to personally experience the power of lifestyle medicine.
