    Author: Kelly RK, Nash R.
    Journal: J Sch Health; 2021 Aug; 91(8):660-669. PubMed ID: 34137459.
    Abstract:
    BACKGROUND: Childhood is a critical period for developing food-related skills and knowledge, known as food literacy (FL). Schools may be an important setting for interventions aiming to improve FL in children. This systematic scoping review aimed to characterize food literacy interventions in elementary schools. METHODS: Databases (PubMed, Web of Science, and EBSCO) were searched for FL interventions in elementary schools (students aged 4-12 years). Studies were assessed according to design, duration, theoretical underpinning, and ascertainment of FL outcome(s). Interventions were assessed according to FL competencies (functional, interactive, and critical). RESULTS: After exclusions, 116 studies were eligible for review, including 105 original interventions. Interventions ranged from 45 minutes to 4 years. Social cognitive theory was the most referenced theory and common interventions included; classroom lessons, games, school gardens, food preparation, and cooking classes. Most studies measured FL outcomes quantitatively (96%, N = 111). All studies addressed functional FL (N = 116), while 77% (N = 89) addressed interactive FL and 28% (N = 32) addressed critical FL. CONCLUSIONS: This first international review of FL programs in elementary schools found great heterogeneity in school-based FL intervention design and measurement of FL. Few interventions addressed critical FL, which should be a focus for future interventions.
