Exploring culinary medicine as a promising method of nutritional education in medical school: a scoping review

Culinary Medicine Experiences for Medical Students and Residents in the U.S. and Canada: A Scoping Review

PHENOMENON

Despite the importance of diet in the prevention and management of many common chronic diseases, nutrition training in medicine is largely inadequate in medical school and residency. The emerging field of culinary medicine offers an experiential nutrition learning approach with the potential to address the need for improved nutrition training of physicians. Exploring this innovative nutrition training strategy, this scoping review describes the nature of culinary medicine experiences for medical students and resident physicians, their impact on the medical trainees, and barriers and facilitators to their implementation.

APPROACH

This scoping review used the Joanna Briggs Institute methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) checklist as guides. Eligible publications described the nature, impact, facilitators, and/or barriers of nutrition and food preparation learning experiences for medical students and/or residents. Additional inclusion criteria were location (U.S. or Canada), allopathic or osteopathic, English, human subjects, and publication year (2002 or later). The search strategy included 4 electronic databases. Two reviewers independently screened titles/abstracts and a third reviewer resolved discrepancies. The full-text review consisted of 2 independent reviews with discrepancies resolved by a third reviewer or by consensus if needed, and the research team extracted data from the included articles based on the nature, impact, barriers, and facilitators of culinary medicine experiences for medical trainees.

FINDINGS

The publication search resulted in 100 publications describing 116 experiences from 70 institutions. Thirty-seven publications described pilot experiences. Elective/extracurricular and medical student experiences were more common than required and resident experiences, respectively. Experiences varied in logistics, instruction, and curricula. Common themes of tailored culinary medicine experiences included community engagement/service-based learning, interprofessional education, attention to social determinants of health, trainee well-being, and cultural considerations. Program evaluations commonly reported the outcome of experiences on participant attitudes, knowledge, skills, confidence, and behaviors. Frequent barriers to implementation included time, faculty, cost/funding, kitchen space, and institutional support while common facilitators of experiences included funding/donations, collaboratives and partnerships, teaching kitchen access, faculty and institutional support, and trainee advocacy.

INSIGHTS

Culinary medicine is an innovative approach to address the need and increased demand for improved nutrition training in medicine. The findings from this review can guide medical education stakeholders interested in developing or modifying culinary medicine experiences. Despite barriers to implementation, culinary medicine experiences can be offered in a variety of ways during undergraduate and graduate medical education and can be creatively designed to fulfill some accreditation standards.

There and Back Again: A Forty-Year Perspective on Physician Nutrition Education

Medical education faces an urgent need for evidence-based physician nutrition education. Since the publication of the 1985 National Academies report "Nutrition Education in the United States Medical Schools," little has changed. Although several key efforts sought to increase nutrition content in undergraduate medical education over the past 40 y, most medical schools still fail to include the recommended minimum of 25 h of nutrition training. Without foundational concepts of nutrition in undergraduate medical education, graduate medical education unsurprisingly falls short of meeting patient needs for nutritional guidance in clinical practice. Meanwhile, diet-sensitive chronic diseases continue to escalate, although largely preventable and treatable by nutritional therapies and dietary lifestyle changes. Fortunately, recent recognition and adoption of Food is Medicine programs across the country increasingly connect patients with healthy food resources and nutrition education as core to their medical care, and physicians must be equipped to lead these efforts alongside their dietitian colleagues. Filling the gap in nutrition training will require an innovative and interprofessional approach that pairs nutrition with personal wellness, interprofessional practice, and community service learning. The intersectional benefits of connecting these domains will help prepare future physicians to address the social, behavioral, and lifestyle determinants of health in a way that recognizes nourishing food access as a core part of clinical practice. There are numerous strategies to integrate nutrition into education pathways, including didactic and experiential learning. Culinary medicine, an evidence-based field combining the culinary arts with nutritional science and medicine, is 1 promising educational framework with a hands-on, interprofessional approach that emphasizes community engagement. Advancing the critical need for widespread adoption of nutrition education for physicians will require support and engagement across societal stakeholders, including co-leadership from registered dietitian nutritionists, health system and payor reform, and opportunities for clinical innovation that bring this essential field to frontline patient care.

Assessing the Impact of Nutrition Training Among Medical Students

Introduction

Nutrition education remains inadequate in American medical schools, and physicians often cite lack of nutrition knowledge as a barrier to counseling patients. The goal of this study was to evaluate the impact of additional nutrition curriculum on first-year medical students.

Methods

We created a 1-hour nutrition lecture, delivered to first-year medical students. Using pre-, post-, and 3-month follow-up surveys, we assessed the following: (1) change in student knowledge; (2) confidence in counseling patients; (3) motivation to change their personal dietary behaviors; and (4) satisfaction with the curriculum. We assessed objectives using multiple choice questions and 10-point Likert scale questions.

Results

Of the 142 students who attended the live lecture, 105 (73.9%) completed both pre- and postsurveys, and 65 (45.8%) completed the 3-month follow-up survey. Students' knowledge of the material increased from 37% to 82%, but retention dropped to 65% at the 3-month mark (P<.001). Comfort in assessing and counseling patients improved across the three survey iterations, from 3.53 to 5.90 to 8.00 (P<.001). Motivation to change personal behaviors was high overall at 8.04, 8.36 and 8.25 [P<.05]). Moreover, students were satisfied with the lecture, with a rating of 8.58/10.

Conclusions

This study supports the value of additional medical student nutrition education. This curriculum significantly increases student knowledge, comfort with the material, and confidence in counseling their future patients. A longitudinal curriculum that reinforces concepts over time will help improve long-term retention.

Evaluation of the reach and utilization of the American College of Lifestyle Medicine's Culinary Medicine Curriculum

Introduction

Despite the growing interest in "food as medicine," healthcare professionals have very limited exposure to nutrition as part of their training. Culinary medicine (CM), an evidence-based field integrating nutrition education with culinary knowledge and skills, offers one approach to fill this training gap. The American College of Lifestyle Medicine published a complimentary Culinary Medicine Curriculum (CMC) in 2019, and the objective of this study is to evaluate its reach and utilization, as well as to collect feedback from users.

Methods

Individuals who downloaded the CMC prior to March 1, 2022 (N = 6,162) were emailed an invitation to participate in an online, cross-sectional survey. The survey included both multiple choice and free-text questions about whether CM sessions were conducted, if and how the CMC was used, if and how it was modified for use, and additional requested resources. Free-text responses were inductively coded, and quantitative data was summarized using descriptive statistics.

Results

A total of 522 respondents provided consent, indicated that they had downloaded the curriculum, and completed the survey. Of the 522, 366 (70%) reported that they had not led or created any CM sessions. The top-reported reason for not leading a session was lack of time (29%). The remaining respondents who did create a CM session did so across various settings, including academic, clinical, coaching, and other settings, and a variety of professionals delivered the CMC sessions, including physicians (50%), registered dietitian nutritionists (30%), and chefs (25%). The majority of respondents (81%) modified the CMC in some way, with many using the curriculum for guidance or ideas only. Patient education materials (66%) and cooking technique instruction videos (59%) were among top requested resources.

Discussion

The CMC is a versatile resource that can be successfully adapted for use across various settings and by various types of health professionals and practitioners. Future research should investigate whether training in CM results in improved health outcomes for patients/clients. The curriculum will continue to grow to address the needs of users by expanding to include more digital content such as curriculum videos and cooking technique videos.

Culinary Medicine or Culinary Nutrition? Defining Terms for Use in Education and Practice

Examination of how terms such as culinary nutrition, culinary nutrition science, culinary medicine, culinary nutrition professional, culinary nutrition intervention, culinary nutrition activity, and culinary nutrition competency are used in practice, and the creation of consensus definitions will promote the consistent use of these terms across work areas and disciplines. Thirty leading practitioners, academics, and researchers in the fields of food and nutrition across Australia, the United States, Canada, United Kingdom, Europe, and Asia were approached by investigators via email to submit definitions of key terms using a Qualtrics survey link. Further participants were reached through snowball recruitment. Initial emails were sent in October and November 2021 with subsequent reminders between November 2021 and March 2022. Two researchers undertook content analysis of the text answers for each of the terms and generated definitions for discussion and consensus. Thirty-seven participants commenced the survey and twenty-three submitted one or more definitions. Agreed definitions fell into two categories: practice concepts and practitioners. Further discussion amongst investigators led to the creation of a visual map to demonstrate the interrelationship of terms. Culinary nutrition science underpins, and interprofessional collaboration characterizes practice in this area, however, further work is needed to define competencies and model best practice.

Development of a Culinary Medicine Curriculum to Support Nutrition Knowledge for Gastroenterology Fellows and Faculty

Gastroenterologists encounter many nutrition-related disorders in their practice, yet the nutritional needs of patients with chronic gastrointestinal (GI) and liver disease are largely unaddressed by treating physicians, due to suboptimal nutrition education. To address this gap, we developed and piloted a culinary medicine course for a GI fellowship training program. The objective of this study is to describe the development, implementation, and acceptability of the course. A registered dietitian, a chef instructor, and a gastroenterology clinical professor trained in culinary medicine developed the four-class tailored curriculum and delivered the classes remotely. Each class had a theme related to commonly encountered GI disorders and included hands-on meal preparation, a nutrition lecture, and a patient case study discussion. Post-course feedback surveys were disseminated. Twenty-three GI physicians enrolled in the course and the attendance rates in classes 1-4 were 83%, 65%, 61%, and 48%, respectively. Among 15 completed feedback surveys, 80% reported that the class contents were either moderately or extremely useful and all endorsed the curriculum for other gastroenterologists. Future studies of culinary medicine programs tailored to medical specialties should identify strategies to maintain engagement and assess the impact on nutrition knowledge, competencies, and translation of these new skills to clinical practice.

The Time is Ripe: The Case for Nutrition in Graduate Medical Education in the United States

A poor-quality dietary pattern is a leading risk factor for chronic disease and death in the United States, and the costs of medical care continue to unsustainably rise. Despite this reality, nutrition training for physicians fails to adequately prepare for them to address the complex factors that influence diet-related disease. Expanding nutrition education for physicians-in-training is imperative to equip them for the growing demand of food is medicine services and is also supported by recent policy efforts in the United States as well as the governing bodies of graduate and undergraduate medical education. A multisector approach that links graduate medical education, clinical care delivery innovation, and health and food policy experts provides momentum to advance nutrition education as a core strategy for food is medicine expansion globally.

Culinary Medicine: Needs and Strategies for Incorporating Nutrition into Medical Education in the United States

In the past decade, medical education has increasingly incorporated evidence-based lifestyle interventions as primary strategies for preventing and managing noncommunicable diseases. This shift embraces the growing recognition of the significant impact of lifestyle on health outcomes, driving diseases including obesity, diabetes, heart disease, and cancer. Now deemed "food is medicine" (FIM), diet-related interventions witnessed integration into healthcare systems and recognition in the United States' White House Conference on Hunger, Nutrition, and Health in 2023. As FIM gains traction, investigating optimal strategies for team-based education becomes essential. Healthcare teams need the necessary knowledge and tools to effectively administer FIM services and collaborate across disciplines, ultimately enhancing disease prevention, chronic disease management, health quality, value, and overall wellness. Culinary medicine (CM), a vital component of FIM, bridges nutrition education, pragmatic culinary skills, and conventional strategies to improve chronic disease management. CM involves experiential learning, imparts practical skills, and encourages behavior change by addressing food-related determinants of health and promoting equitable access. Teaching kitchens serve as physical or virtual learning spaces and as a didactic and experiential method (skills lab), playing a crucial role by integrating culinary, lifestyle, integrative, and conventional medicine. A growing number of medical schools in the United States and globally offer CM education via diverse methods including interest groups, electives, and specialty tracks, encompassing didactic sessions, hands-on kitchen education, and virtual teaching methods. Given the rising demand for CM programs, this article aims to describe, map, and compare existing CM education types in medical education. It provides actionable recommendations for medical schools to establish and expand CM programs by fostering service-learning partnerships, clinical innovation, and interdisciplinary research. As FIM gains prominence, cultivating a robust foundation of educational strategies is vital to ensure seamless integration into both medical education and collaborative medical practice.

Occupational therapy and cooking: A scoping review and future directions

BACKGROUND

Occupational therapy (OT) has historically used cooking as an intervention and assessment approach across settings. Current practices in OT and the emergence of the multidisciplinary field of culinary medicine highlight the relationship between cooking and health.

AIMS/OBJECTIVES

To map the current literature on OT and cooking and to identify key factors that may facilitate collaboration within culinary medicine.

MATERIALS AND METHODS

We conducted a scoping review using the Joanna Briggs Institute methodology to identify primary contexts and clinical settings. Publications were analysed using framework thematic analysis to identify OT themes and roles.

RESULTS

A total of 56 studies met the criteria for inclusion. The majority of studies (n = 29, 53%) represented home/community settings and brain injury was the largest clinical group (n = 15, 27%). Primary themes related to person (n = 47, 43%), occupation (n = 30 (28%), environment (n = 19, 17%), and psychosocial wellbeing (n = 13, 12%). The primary OT role identified was that of interventionist (n = 48, 86%).

CONCLUSIONS/SIGNIFICANCE

OT's holistic practice places cooking within a larger context that can help identify and overcome the barriers to participation. Findings support multiple pathways in which OT can contribute to cooking initiatives for health promotion and potentially expand OT practice in population health.

Food Is Medicine: A Presidential Advisory From the American Heart Association

Unhealthy diets are a major impediment to achieving a healthier population in the United States. Although there is a relatively clear sense of what constitutes a healthy diet, most of the US population does not eat healthy food at rates consistent with the recommended clinical guidelines. An abundance of barriers, including food and nutrition insecurity, how food is marketed and advertised, access to and affordability of healthy foods, and behavioral challenges such as a focus on immediate versus delayed gratification, stand in the way of healthier dietary patterns for many Americans. Food Is Medicine may be defined as the provision of healthy food resources to prevent, manage, or treat specific clinical conditions in coordination with the health care sector. Although the field has promise, relatively few studies have been conducted with designs that provide strong evidence of associations between Food Is Medicine interventions and health outcomes or health costs. Much work needs to be done to create a stronger body of evidence that convincingly demonstrates the effectiveness and cost-effectiveness of different types of Food Is Medicine interventions. An estimated 90% of the $4.3 trillion annual cost of health care in the United States is spent on medical care for chronic disease. For many of these diseases, diet is a major risk factor, so even modest improvements in diet could have a significant impact. This presidential advisory offers an overview of the state of the field of Food Is Medicine and a road map for a new research initiative that strategically approaches the outstanding questions in the field while prioritizing a human-centered design approach to achieve high rates of patient engagement and sustained behavior change. This will ideally happen in the context of broader efforts to use a health equity-centered approach to enhance the ways in which our food system and related policies support improvements in health.

Empowering Future Physicians and Communities on Chicago's South Side through a 3-Arm Culinary Medicine Program

The purpose of this pilot evaluation was to assess the impact of a university culinary medicine program on participating medical students and community members, which included individuals managing chronic illness and public middle school students. A total of 59 program participants enrolled in the study. Data were obtained using pre- and post-course surveys and qualitative interviews from September 2021-July 2023. Results show increased confidence in medical students' ability to provide nutrition counseling, with a high significance in their ability to provide counseling regarding chronic conditions. Participants managing chronic conditions demonstrated significant increases in self-reported confidence in their understanding of overall chronic disease management and care and in their kitchen skills, with participants who attended five or more classes having significantly higher means. Qualitative feedback from middle school students highlights their knowledge and willingness to try new foods after engaging with the curriculum. Findings add to the growing literature on culinary medicine and provide insight into the effectiveness of culinary medicine programming to increase knowledge and promote positive changes among future healthcare professionals and community members. However, more extensive research across a longer time span is needed to confirm the potential for sustained change.

"Zoom"ing to the Kitchen: A Novel Approach to Virtual Nutrition Education for Medical Trainees

While nutritional interventions are first-line therapy for many chronic diseases, most medical trainees receive minimal nutrition education, leaving them unprepared to address nutritional issues with patients. An interactive, single-session, virtual nutrition curriculum was taught online to 80 physician assistant (PA) students. Topics included plant-based nutrition, dietary history-taking and counseling, and culinary medicine. Students were surveyed before, immediately after, and four weeks after the curriculum to assess changes to nutrition-related knowledge, attitudes, confidence, and personal dietary behaviors. Seventy-three PA students (91%) completed the pre-survey, 76 (95%) completed the post-survey, and 42 (52.5%) completed the delayed post-survey. Knowledge scores increased immediately post-intervention (48.9% to 78.9%; p < 0.001) and persisted four weeks later (78.9% to 75.8%; p = 0.54). Post-intervention, students felt more confident in dietary history-taking (55% vs. 95%; p = 0.001) and nutrition counseling (53% vs. 84%; p = 0.003) and agreed that dietary changes alone could reverse type 2 diabetes (74% vs. 97%; p = 0.027) and coronary artery disease (66% vs. 92%; p = 0.039). Curricula using virtual teaching kitchens may be a scalable approach to nutrition education for medical trainees.

Impact of Culinary Medicine Course on Confidence and Competence in Diet and Lifestyle Counseling, Interprofessional Communication, and Health Behaviors and Advocacy

Most physicians report inadequate training to provide diet and lifestyle counseling to patients despite its importance to chronic disease prevention and management. To fill the nutrition training gap, elective Culinary Medicine (CM) courses have emerged as an alternative to curriculum reform. We evaluated the impact of an interprofessional CM course for medical and health professional students who experienced the hands-on cooking component in person or a in mixed-mode format (in-person and via Zoom) at the University of Utah from 2019-2023 (n = 84). A factorial ANOVA assessed differences between educational environment and changes between pre- and post-course survey responses related to diet and lifestyle counseling, interprofessional communication, and health behaviors and advocacy. Qualitative comments from post-course surveys were analyzed on a thematic level. Students rated themselves as having greater confidence and competence in diet and lifestyle counseling (p < 0.05) and increased ability to prepare eight healthy meals (p < 0.05). Additionally, a Mann-Whitney two-sample rank-sum test was used to compare data from exit survey responses from medical students who took the CM course (n = 48) and did not take the CM course (n = 297). Medical students who took CM were significantly more likely to agree that they could counsel patients about nutrition (p < 0.05) and physical activity (p < 0.05). CM courses may improve students' confidence to provide diet and lifestyle counseling.

Redesigning Recruitment and Engagement Strategies for Virtual Culinary Medicine and Medical Nutrition Interventions in a Randomized Trial of Patients with Uncontrolled Type 2 Diabetes

In-person culinary medicine (CM) can improve health behaviors, but its translation to virtual platforms and impact on diabetes outcomes are not well described. We designed a pragmatic trial comparing the effectiveness of virtual CM (eCM) to Medical Nutrition Therapy on diabetes outcomes among patients with uncontrolled diabetes within a safety-net healthcare system. All participants were provided cooking equipment and food from a food pantry. Due to low initial eCM participation, recruitment was paused, and eight semi-structured interviews were conducted to solicit feedback on study appeal, operations, and barriers to participation. Rapid thematic analysis was used to modify study operations. We found that participants were interested in the study and motivated by health concerns. While they valued food distribution and cooking equipment, they highlighted transportation barriers and conflicts with the pick-up time/location. Some eCM participants expressed discomfort with the virtual platform or preferred to observe rather than cook along. Study operations were modified by (1) moving supply pick-up to a familiar community clinic and diversifying food pick-up locations; (2) offering an in-person orientation to the program to increase comfort with the virtual platform; (3) emphasizing the credibility and relatability of the eCM instructor and encouraging participation of family members. This redesign led to the recruitment of 79 participants, of whom 75% attended at least one class. In conclusion, participant feedback informed pragmatic changes in study operations that increased engagement in this ongoing trial and may inform future eCM program design.

Physician-Chef-Dietitian Partnerships for Evidence-Based Dietary Approaches to Tackling Chronic Disease: The Case for Culinary Medicine in Teaching Kitchens

Since the middle of the 20th century, the American food environment has become increasingly ultra-processed. As a result, the prevalence of chronic, diet-related disease in the United States has skyrocketed. Meanwhile, physicians are still poorly trained in nutrition. A recent innovation that aims to address this is "culinary medicine" programming taught by teams of physicians, chefs, and registered dietitian nutritionists. Culinary medicine is an evidence-based, interprofessional field of medicine that combines culinary arts, nutrition science, and medical education to prevent and treat diet-related disease. It employs hands-on learning through healthy cooking and is typically taught in a teaching kitchen, either in-person or virtually. It can be dosed either as a patient care intervention or as experiential nutrition education for students, medical trainees, and healthcare professionals. Culinary medicine programs are effective, financially feasible, and well-received. As a result, healthcare systems and medical education programs are increasingly incorporating culinary medicine, teaching kitchens, and interprofessional nutrition education into their patient care and training models.

Creating Teams of Family Medicine Residents and High School Culinary Students Reduces Some Barriers to Implementing a Culinary Medicine Hands-On Workshop

Background

Barriers to implementation of culinary medicine in resident training include lack of facilities, administrative support, and community engagement.

Activity

Twenty-five family medicine residents were teamed with 17 high school culinary arts students to prepare recipes aligned with the Mediterranean diet (MED) and the USDA low, moderate, and liberal cost food plans.

Results

The workshop took place in the high school teaching kitchens. A pre-survey informed the planning committee's design of a 4-h hands-on workshop that was considered a success.

Discussion

Post-surveys documented improved resident confidence and skills in recommending MED to their patients and interaction with their own peers and high school students, as well as enjoyment by all participants of this hands-on approach.

Uncovering culinary medicine research themes: Current status and future direction

Background: Culinary medicine (CM), an emerging discipline, is a novel approach that focuses on the art of food and cooking to prevent or improve health outcomes among chronic patients suffering from lifestyle diseases. The concept originated in the USA, gaining interest from scholars in medicine, nutrition, nursing, and the gastronomic discipline. Notably, in the last five years, there has been exponential growth in CM literature. In this regard, this study sought to examine the growth, performance and distinct research themes of CM literature over time. Methods: To achieve the study's objectives, this study employs descriptive, performance and bibliometric analysis. The descriptive analysis was applied to examine the growth of the CM literature since its emergence. The performance analysis was used to identify the most influential journals, articles, and authors in the CM domain. The bibliographic coupling analysis was adopted to discover the various research themes of the CM knowledge base. Results: This study identifies three stages of literature development: Early stage, modest growth stage, and emerging stage. Further, the results indicate that most of the studies on CM had been conducted in developed countries. Our findings reveal a clear interest in integrating the CM curriculum into medical/nutrition education programs in recent years. Additionally, the study discovers four distinct main research themes: knowledge assessment, impact measurement, acceptance and efficacy, and implementation of CM. Conclusions: These findings are helpful for scholars in medicine, nutrition, nursing, and gastronomy as they provide an overview of CM's development and research focus. Future studies could focus on expanding the geographical distribution of research on CM and further exploring the identified research themes to gain a deeper understanding of the potential of this approach for improving health outcomes among chronic disease patients.
