LGEG was developed for the research project described below and was shaped by the data collected by the study. See the research overview and infographic.
Texas Grow! Eat! Go! is a 5 year school garden, nutrition, and physical activity intervention study targeting childhood obesity among
third grade students in 28 Title 1 schools. The study evaluated a child-obesity-prevention model based on the Coordinated Approach to Child Heath (CATCH).
CATCH was enhanced by two Texas A&M AgriLife Extension Service programs: Walk Across Texas, and Junior Master Gardener. Each extension program improved the physical activity and eating behaviors of children–both of which are associated with healthy weight.
The home environment was targeted through the two Extension programs delivered by teachers but supported by local Extension agents and volunteers such as Master Gardeners and Master Wellness Volunteers, who could provide a strong family and community connection necessary to sustain the model.
A randomized, controlled trial study was designed by a team of Extension Specialists and researchers from Texas A&M University and the TAMU and University of Texas Schools of Public Health. The study was funded by a grant from the National Institute of Food and Agriculture, an agency of the U.S. Department of Agriculture.

Highlights of the report include:
- Over 85% of respondents stated that JMG has increased youth interest in science. (Cummings and Boleman, 2002)
- Over 83% of respondents said youth were more enthusiastic about learning (Cummings and Boleman, 2002)
- Over 85% of teachers/leaders plan to continue using the JMG program with youth (Cummings and Boleman, 2002)
- 69% of teachers and leaders said that JMG has encouraged students to perform community service projects outside the classroom. (Cummings and Boleman, 2002)
- Over 63% said youth tried new fruits and vegetables (Cummings and Boleman, 2002)
Third and fifth graders showed more positive attitudes toward fruit and vegetable snacks and an improvement in vegetable preference scores after completing activities from a nutrition gardening currriculum.

“Children participating in activities from Health and Nutrition from the Garden had improved knowledge concerning the benefits of eating fruits and vegetables, and demonstrated an increase in healthier snack consumption after the study.”

“Qualitative data also indicated that the students enjoyed the program, shared what they learned with others, and wanted to participate in more JMG and gardening type activities .”
An Evaluation of the Junior Master Gardener Program in Third Grade Classrooms
Amy E. Dirks and Kathryn Orvis
“Eat Your Way to Better Health (EYWTBH) is a garden-based nutrition education program that was conducted and evaluated for 3 years in Indiana third-grade classrooms. Program participants started and maintained their own school gardens as a part of an authentic experiential learning curriculum designed to reconnect youth with where their food comes from and educate about healthy eating habits. Implementation lasted between 8 and 12 weeks and outcomes were evaluated using pre- and postprogram questionnaires. Results showed that upon completion of the EYWTBH program, youth reported a higher healthy food choice self-efficacy, as well as a higher variety of fruit and vegetable consumption. Relationships among the variables were identified and discussed in the context of improving future school garden nutrition programs.”

Studies have shown that fifth, sixth, and seventh grade students developed better interpersonal relationship skills after participating in a garden program.

95.8 % rate school gardening is a somewhat successful or very successful teaching tool
92% teachers surveyed requested additional school gardening education for themselves

Gardens in low-income neighborhoods (46%) were four times as likely as non low-income gardens to lead to other issues in the neighborhood being addressed; reportedly due to organizing facilitated through the community gardens.
“Children (in housing project) see it (the garden) as an actual piece of land that they have control over, the have pride of ownership.”

Garden-enhanced nutrition curriculum improves fourth-grade school children’s knowledge of nutrition and preferences for some vegetables. The results lend support to the inclusion of vegetable gardens within the school setting.
Administrators of future school garden projects are encouraged to include a wide variety of fruits and vegetables in their garden programs.
