Obesity: Meal or Fruit and Vegetable Snack Interventions to Increase Healthier Foods and Beverages Provided by Schools

CDC

An Evidence-Based Practice

Description

Meal interventions or fruit and vegetable snack interventions aim to provide healthier foods and beverages that will be consumed by students, limit access to less healthy foods and beverages, or both.

Interventions must include one of the following components:
-School meal policies that ensure school breakfasts or lunches meet specific nutrition requirements (e.g., School Breakfast Program, National School Lunch Program)
-Fresh fruit and vegetable programs that provide fresh fruits and vegetables to students during lunch or snack

Healthier foods and beverages include fruits, vegetables, whole grains, low-fat or fat-free dairy, lean meats, beans, eggs, nuts, and items that are low in saturated fats, salt, and added sugars, and have no trans fats. Less-healthy foods and beverages include those with more added sugars, fats, and sodium.

Impact

The Community Preventive Services Task Force (CPSTF) recommends meal interventions and fruit and vegetable snack interventions to increase the availability of healthier foods and beverages provided by schools. This finding is based on evidence that they increase fruit and vegetable consumption and reduce or maintain the rate of obesity or overweight. Economic evidence shows that meal interventions and fruit and vegetable snack interventions are cost-effective.
