Medical and Health Professions Students:

Various aspects of culinary medicine started in 2019 at NSU Florida through an innovative collaboration of faculty leaders from the Dr. Kiran C. Patel College of Osteopathic Medicine and the Dr. Kiran C. Patel College of Allopathic Medicine, members of the Health Professional Division at Nova Southeastern University. Growing interest from students continues to generate new programming and expanded options to access the Health meets Food programming.

Allopathic medicine students have the option to take a 2-week elective course in culinary medicine in their 4th year. This virtual course has synchronous meetings and interactive learning groups as they work through the required modules addressing chronic disease. Graduate students in the Master of Biomedical Sciences may also take an elective course in culinary nutrition similarly.

Osteopathic medical students take a personal wellness course in the first-year curriculum. Lessons from Health meets Food program have been presented in small-group workshops using the modules. An elective course for osteopathic medical students is currently under development.

NSU is building a state-of-art interprofessional simulation complex to open in the Fall of 2024. The design includes a teaching kitchen and culinary theater to house the future plans for growing the culinary medicine program.
