Adherence
The widespread availability of competitive foods (sodas, snacks) in schools is causally linked to increased total calorie, fat, and sugar intake and decreased fruit and vegetable consumption in students.
If you are a school administrator, do not assume that removing soda and chips will bankrupt your food service. Evidence indicates that schools can upgrade to healthier options without losing revenue, and students may actually choose the school lunch more often if the junk food alternatives are gone.
GoodSupportsHIGH confidence
Several studies have related the availability of snacks and drinks sold in schools to higher intakes of total calories, soft drinks, total fat and saturated fat, and lower intakes of fruits and vegetables, milk, and key nutrients (Cullen et al. 2000; Cullen and Thompson 2005; Cullen and Zakeri 2004; Kubik et al. 2003).
Why this rating
