The influence of school food policies on fruit and vegetable intake and body weight.
School food policies consist of standards, guidelines, and/or programs aiming to alter food environments in the school setting. The World Health Organization (WHO) recommends several school food policy options to combat obesity, including: diet-focused health education, nutrition standards and subsidies, maintaining convenient and welcoming food service areas, regulating the marketing of unhealthy food products, and communication and outreach with food vendors near schools (1).
Despite such recommendations, many schools have yet to implement healthy school food policies, and those that have are yet to be researched or evaluated. This brief summarizes the impact of school food policies and interventions on students’ fruit and vegetable intake and body weight outcomes.
- Nutritional guidelines and subscription/distribution programs may be promising options to increase students’ intake of fruit and vegetables and improve dietary behavior, especially if paired with an educational component (2, 3).
- Multi-component interventions with broader health promotion mandates may have positive impacts on dietary behaviours, including intake of fruits and vegetables, and BMI or weight outcomes (2-4).
