Objectives: To summarise findings of systematic reviews that distinctively report dietary intervention components and its effects on diet-, health-related and economic-related outcomes in the workplace setting.

Design: Medline, EMBASE, CINAHL, Web of Science, Cochrane Library and Google Scholar were 6 searched in December 2014 and the search was updated in August 2017.

Results: The search identified 1137 titles, of which 19 systematic reviews from the initial search and two systematic reviews from the updated search met the inclusion criteria (n=21, published in 22 papers). Most systematic reviews were of moderate quality and focused on dietary behaviour change outcomes and some health-related biomarkers. Evidence was strongest for interventions to increase fruit and vegetable intake, reduce fat intake, aid weight loss and reduce cholesterol. Few reported workplace-related and evaluation outcomes.

Conclusions: These findings suggest that workplace dietary interventions can positively influence diet and health outcomes. Suggestions for effective interventions components have been made.
