Using Herbs and Spices to Increase Children's Acceptance and Intake of Vegetables in School Lunches

January 3, 2018 updated by: Kathleen Loralee Keller, Penn State University
Herbs and spices offer one potential solution to the recent decline in children taking school lunch because they can increase the palatability of foods without adding salt and fat. However, there is currently limited evidence on how to successfully integrate herbs and spices into the school lunch menu. Developing evidence-based methods to teach school cafeteria workers to prepare healthy and tasty vegetable dishes with the addition of herbs and spices is a research priority. The investigators hypothesize that herbs and spices can be used to increase acceptance, intake, and participation in the school lunch program among 6th - 12th grade students from Central Pennsylvania.

Detailed Description

What this study will add to the literature: Herbs and spices offer one potential solution to the recent decline in children taking school lunch because they can increase the palatability of foods without adding salt and fat. However, there is currently limited evidence on how to successfully integrate herbs and spices into the school lunch menu. Developing evidence-based methods to teach school cafeteria workers to prepare healthy and tasty vegetable dishes with the addition of herbs and spices is a research priority. This research will provide evidence that herbs and spices can be used to increase acceptance, intake, and participation in the school lunch program among 6th - 12th grade students from Central Pennsylvania.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Surveys defining barriers to vegetable consumption at Bald Eagle Area Middle/High School
Time Frame: Baseline
Conduct surveys of students, parents and food service experts to gather information describing ways to increase vegetable intake at Bald Eagle Area Middle/High School
Baseline
Taste tests to quantify the change in liking of vegetable recipes
Time Frame: Baseline and after recipe development (approximately 10 months). Prior to intervention.
Student's liking of vegetables prepared with herbs/spices will be assessed during the taste tests by setting up sensory panels in their culinary and consumer education classes. Participating students will rate liking and will provide written feedback to inform recipe development.
Baseline and after recipe development (approximately 10 months). Prior to intervention.
Change in vegetable plate waste
Time Frame: Baseline, Intervention and Follow-up (1 and 6 months)
Weight of vegetable disappearance from the school cafeteria, minus waste weight, in kg.
Baseline, Intervention and Follow-up (1 and 6 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
School lunch program participation
Time Frame: Baseline, Intervention and Followup (1 and 6 months)
Percentage of children who are participating in the school lunch program will be assessed the school years prior to and immediately after the intervention
Baseline, Intervention and Followup (1 and 6 months)
Post-meal comment cards
Time Frame: Baseline, Intervention and Followup (1 and 6 months)
Student's will rate satisfaction with the school lunches by completing anonymous, post-meal comment cards during the baseline, intervention, and follow-up phases.
Baseline, Intervention and Followup (1 and 6 months)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
