The Small Bites Program is a direct education intervention designed to increase nutrition knowledge, vegetable consumption, and variety of vegetables consumed. The curriculum teaches students about nutrition and healthy cooking through a series of eight (or more) 1-hour lessons combining nutrition and knife-free cooking. In every lesson, students prepare a healthy snack, using recipes that meet USDA Guidelines, and provide opportunities to learn about and reinforce nutrition concepts and cooking skills. The lessons are grade-level banded, suitable for the in-school or after-school setting and are designed to support core content learning in math, English Language Arts, and science. 

Intervention Target Behavior: Healthy Eating

SNAP-Ed Strategies: Direct Education

Intervention Reach and Adoption

Small Bites targets preschool, elementary, and middle school aged children in a variety of settings. Small Bites has been adopted in community and education-based settings (both in-school and after-school) that work with at least 50% free and reduced lunch populations or at sites located in census tracts where at least 50 percent of persons have gross incomes that are <185 percent of the poverty threshold. The number of students reached by the intervention from 2012-2021 totals 339,000 students. Since 2015, Common Threads collected site-based data and has worked with 2,600+ sites.

Settings: Farmers markets, Pre-k & Childcare, Community-wide, Faith-based centers, Food pantries, Healthcare, Schools, USDA program sites

Age/Population Group: Preschool, Elementary School, Middle School

Race: All

Ethnicity: All

Intervention Components

Small Bites includes eight 1-hour nutrition education lessons that incorporate a healthy snack making component, cultural education, core content alignment to national and state standards and extension lessons. Lessons are available for in-person or virtual programs. These intervention components provide improved child nutrition knowledge, child attitudes about eating fruit and vegetables, intention to eat healthy food, food preparation skills, self-efficacy for preparing healthy snacks at home, and positive attitudes and perceived norms about preparing meals at home. Inputs necessary to implement the intervention include teaching staff, funding, student and parent recruitment, school/administrator commitment, facilities, and volunteers. Classroom intervention components provide increased teacher support for Common Core, Next Generation Science Standards, various local education standards, in classroom instruction and student engagement. To achieve targeted behaviors it is recommended that the program be completed in at least 8 weeks with at least 8 or more lessons.

Intervention Materials

Materials include online self-paced training for educators, student videos, digital curriculum access, and recipes which meet USDA guidelines. Lesson plans are for in-person or virtual programming. Resources are available for a fee via  Resources are available for a fee via

Evidence Summary

Common Threads places high value on research and evaluation and we have conducted continuous, annual, and internal evaluation of programs since 2016. We use a quasi-experimental pre-post survey design with Wilcoxon paired tests to determine if there was a significant change in participant responses. During the 2017-2018 academic year, we achieved the following national outcome after participating in Small Bites:

  • Net 22.4% of students answered more nutrition knowledge questions correctly than they did before participating (p<.001)
  • Net 10% of students had been exposed to more vegetables (p<.001)
  • Net 13% increased their liking for vegetables (p<.001)
  • Net 16% increased their consumption of vegetables (p<.001)
  • Net 8% increased the variety of vegetables they consumed (p=.002)
  • Net 7% were more confident in their ability to make a healthy snack (p=.03)

Evidence Base: Practice-tested

Evaluation Indicators

Based on the SNAP-Ed Evaluation Framework, the following outcome indicators can be used to evaluate intervention progress and success.

Environmental Settings   
Sectors of Influence   
  • ST1: In school year 2017-2018, net 21% of students increased their nutrition knowledge (p<.001)
  • MT1: In school year 2017-18, net 7% of students increased the amount of vegetables consumed the previous day (p=.02)
  • MT1d: In school year 2017-18, net 8% of students increased the variety of vegetables they consumed the previous day (p=.002)
  • MT1m: In school year 2017-2018, median Veggie Meter measurement (measurement of carotenoids in the skin) increased from 257 before programming to 263 after programming (p=.04)
