To examine the impact of a community culinary coaching programme (CCCP) on cafeteria food alignment with a freshly prepared Mediterranean-style diet, and diners’ consumption habits and satisfaction.

A non-randomized, controlled, community-based participatory research programme. CCCP included eight 90 min coaching sessions with a community steering committee, 22 h of kitchen staff training, 12 h of pre-school staff training and 30 h of education for diners; control communities received no intervention. Outcomes, measured before and 12 months after programme initiation, included cafeteria food alignment with a freshly prepared Mediterranean-style diet through a food items list derived from the cafeteria food purchasing software, and adult diners’ consumption habits and satisfaction through questionnaires.

Communal cafeterias of rural kibbutzim.

Intervention: kibbutz with 493 adults and 214 children. Control: Two kibbutzim with a total of 487 adults and 206 children.

Intervention cafeteria food improved significantly in all Mediterranean index categories except nuts (legumes, wholegrain products, fish, MUFA/SFA P < 0·0001; fruits, vegetables P < 0·001; processed meats P = 0·004), and in the proportion of ultra-processed and unprocessed or minimally processed foods categories of the NOVA classification (−22 %, P < 0·001 and +7 %, P < 0·001, respectively), compared with the control community. The intervention group’s satisfaction was significantly improved in twenty-five (83 %) out of the thirty satisfaction items, compared with twelve (40 %) in the control group. No changes were identified in diners’ consumption habits in either intervention or control communities.

CCCP might be useful in improving alignment of cafeteria food with a freshly prepared Mediterranean-style diet.
