Background: Beneficial correlations are suggested between food preparation and home food preparation of healthy choices. Therefore, there is an emergence of culinary medicine (CM) programs directed at both patients and medical professionals which deliver education emphasizing skills such as shopping, food storage, and meal preparation. Objective: The goal of this article is to provide a description of emerging CM programs and to imagine how this field can mature. Methods: During April 2015, 10 CM programs were identified by surveying CM and lifestyle medicine leaders. Program directors completed a narrative describing their program's structure, curricula, educational design, modes of delivery, funding, and cost. Interviews were conducted in an effort to optimize data collection. Results: All 10 culinary programs deliver medical education curricula educating 2654 health professionals per year. Educational goals vary within the domains of (1) provider's self-behavior, (2) nutritional knowledge and (3) prescribing nutrition. Six programs deliver patients’ curricula, educating 4225 individuals per year. These programs’ content varies and focuses on either specific diets or various culinary behaviors. All the programs’ directors are health professionals who are also either credentialed chefs or have a strong culinary background. Nine of these programs offer culinary training in either a hands-on or visual demonstration within a teaching kitchen setting, while one delivers remote culinary tele-education. Seven programs track outcomes using various questionnaires and biometric data. Conclusions: There is currently no consensus about learning objectives, curricular domains, staffing, and facility requirements associated with CM, and there has been little research to explore its impact. A shared strategy is needed to collectively overcome these challenges.

The coronavirus pandemic enforced social restrictions with abrupt impacts on mental health and changes to health behaviors. From a randomized clinical trial, we assessed the impact of culinary education on home cooking practices, coping strategies and resiliency during the first wave of the COVID-19 pandemic (March/April 2020). Participants (n = 28) were aged 25–70 years with a BMI of 27.5–35 kg/m2. The intervention consisted of 12 weekly 30-min one-on-one telemedicine culinary coaching sessions. Coping strategies were assessed through the Brief Coping with Problems Experienced Inventory, and resiliency using the Brief Resilient Coping Scale. Home cooking practices were assessed through qualitative analysis. The average use of self-care as a coping strategy by the intervention group was 6.14 (1.66), compared to the control with 4.64 (1.69); p = 0.03. While more intervention participants had high (n = 5) and medium (n = 8) resiliency compared to controls (n = 4, n = 6, respectively), this difference was not significant (p = 0.33). Intervention participants reported using home cooking skills such as meal planning and time saving techniques during the pandemic. The key findings were that culinary coaching via telemedicine may be an effective intervention for teaching home cooking skills and promoting the use of self-care as a coping strategy during times of stress, including the COVID-19 pandemic.

By 2020, the World Health Organization predicts that two-thirds of all diseases worldwide will be the result of lifestyle choices. Physicians often do not counsel patients about healthy behaviors, and lack of training has been identified as one of the barriers. Between 2010 and 2014, Hebrew University developed and implemented a 58-h Lifestyle Medicine curriculum spanning five of the 6 years of medical school. Content includes nutrition, exercise, smoking cessation, and behavior change, as well as health coaching practice with friends/relatives (preclinical years) and patients (clinical years). This report describes this development and diffusion process, and it also presents findings related to the level of acceptance of this student-initiated Lifestyle Medicine (LM) curriculum. Students completed an online semi-structured questionnaire after the first coaching session (coaching questionnaire) and the last coaching session (follow-up questionnaire). Nine hundred and twenty-three students completed the coaching questionnaire (296 practices were with patients, 627 with friends /relatives); and 784 students completed the follow-up questionnaire (208 practices were with patients, 576 with friends /relatives). They reported overall that health coaching domains included smoking cessation (263 students), nutrition (79), and exercise (117); 464 students reported on combined topics. Students consistently described a high acceptance of the curriculum and their active role in coaching. Further, most students reported that they were eager to address their own health behaviors. We described the development and acceptance of a student-initiated comprehensive LM curriculum. Students perceived LM as an important component of physicians’ professional role and were ready to explore it both as coaches and in their personal lives. Thus, medical school deans might consider developing similar initiatives in order to position medical schools as key players within a preventive strategy in healthcare policy.

Nutrition therapy as part of lifestyle care is recommended for people with type 2 diabetes. However, most people with diabetes do not follow this guideline. Changing eating habits involves obtaining knowledge and building practical skills such as shopping, meal preparation, and food storage. Just as fitness coaches use their specific knowledge base in fitness to enhance the effectiveness of their coaching, credentialed chefs trained as health coaches might combine their culinary expertise with coaching in order to improve clients’ food choices and lifestyles. This report documents the case of a 55-year-old white male physician, single and living alone, who was recently diagnosed with type 2 diabetes and reported chronic stress, sedentary behavior, and unhealthy eating habits. He participated in a chef coaching program of 8 weekly one-on-one 30-minute coaching sessions via Skype delivered by a chef trained as a health coach. During the first five meetings, the patient's goals were primarily culinary; however, with his success in accomplishing these goals, the patient progressed and expanded his goals to include other lifestyle domains, specifically exercise and work-life balance. At the end of the program, the patient had improved both his nutritional and exercise habits, his confidence in further self-care improvement, and his health parameters such as HgA1c (8.8% to 6.7%; normal <6.5%). We conclude that chef coaching has the potential to help people with diabetes improve their practical culinary skills and implement them so that they eat better and, further, has the potential to help them improve their overall self-care. We intend to further develop chef coaching and assess its potential as we learn from its implementation.

Background: Nutrition medical education training programs that are focused on home cooking are emerging. Objective: This short communication describes the first synchronous tele-nutrition medical education training program using a novel Culinary Coaching (CC) model. Design: Seven health coaches were trained and each coach delivered CC programs to four patients (28 total). Evaluations included:1) two questionnaires before, immediately after, and six months post training program; and 2) one questionnaire after each patient program. Results: CC training significantly improved coaches’ attitudes about and confidence to deliver CC from pre-program means of 3.61 and 3.65 (out of 5), respectively, to post-program means, 3.77 (p<0.01) and 3.86 (p<0.05), respectively, and remained higher 6 months after the training program (3.93, p<0.01; 3.93, p<0.05). Health coaches described a high usage of CC principles and tools through the patient programs. Conclusions: This early evidence suggests that the CC model can be successfully expanded to health coaches, thus improving nutritional care.
