Awareness of nutrition's role in chronic diseases is rising, demanding guidance on the diet-disease relationship. Nutritional practices become crucial for prevention, prompting healthcare professionals (HCP) to respond. The present study assessed a Culinary Medicine (CM) program's impact on HCP's Mediterranean diet adherence, food and diet therapy knowledge, food management skills, culinary proficiency, and counseling confidence. A mixed-methods pilot implementation program (PIP) engaged 20 HCP from Hospital Clinic Barcelona at the Alícia Foundation kitchen-lab. Four 8-hour CM sessions, held weekly, covered culinary knowledge emphasizing disease prevention and care. All twenty participants; 86% women, 14% men, 86% aged above 40, 14% between 31 and 39 years, 71% nurses, 7% medical doctors and 21% other occupation, completed the course and fourteen fulfilled pre-and post-program questionnaires. Notably, 86% had prior nutrition training, while only 14% had culinary training. After the program, there was significant improvement in Mediterranean diet adherence ( < .05). Perceptions on dietary advice usefulness, patient-transferable knowledge acquisition, cooking techniques, and personal cooking skills confidence showed post-course improvements. This study underscores the potential of hands-on CM training in HCP nutrition education, influencing their culinary knowledge. Future studies with larger samples is needed to elucidate CM training's impact on HCP and potential public health benefits.
