Comprehensive mapping of national school food policies across the European Union plus Norway and Switzerland

Childhood obesity is a major public health challenge in Europe. Schools are seen as an important setting to promote healthy diet and lifestyle in a protected environment and school food-related practices are essential in this regard. To understand what policy frameworks European countries have created to govern these practices, a systematic assessment of national school food policies across the European Union plus Norway and Switzerland (n = 30 countries) was carried out. The survey revealed that all 30 countries currently have a school food policy in place; a total of 34 relevant policies were identified, 18 of which were mandatory and the remaining 16 voluntary. Major policy objectives specified were those to improve child nutrition (97% of policies), to help children learn and adopt healthy diet and lifestyle habits (94%) and to reduce or prevent childhood obesity (88%). Most commonly (> 90%), the policies offered food-based standards for menu composition, and portion sizes were guided by age-appropriate energy requirements. Lunch and snacks were the most widely addressed mealtimes for almost 90% of all policies examined. Other important areas covered included food marketing to children; the availability of vending services; training requirements for catering staff; and whether nutrition education is a mandatory part of the national curriculum. Evaluation was mentioned in 59% of the school food policies reviewed. Future analyses should focus on evaluating the implementation of these policies and more importantly, their effectiveness in meeting the objectives defined therein. Comparable and up-to-date information along with data on education, attainment and public health indicators will enable a comprehensive impact assessment of school food policies and help facilitate optimal school food provision for all.
