Impact of Convenience on Whole Grain Consumption (WG)
Impact of Convenience on Consumption of Intact Novel Whole Grains: A Comparison Between Ready-to-Eat and Dried Conditions
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
The investigators will evaluate the effects of convenience on intake of intact whole grains. Forty-two participants (19 years or older) will be randomized to receive intact whole grains of barley, buckwheat, and quinoa in either a convenient ready-to-eat (RTE) form or a bulk (DRIED) form. Enrollment in the study will continue until 42 participants have completed the study. Recruitment will include posters, word-of-mouth, and online newsletters. Interested individuals will complete an online survey to determine initial eligibility. Eligible participants will be contacted by study staff and invited to an in-person orientation session. At the in-person visit, participant eligibility will be verified. Eligible participants will review and sign the informed consent form. Using standard clinical protocols, trained research staff will collect baseline measurements of height and weight, randomize participants to either the RTE or DRIED condition, provide education on whole grains and how to prepare the study grains, and provide participants with a link to complete a questionnaire about eating habits. Lastly, participants will be sent home with the 7 days' worth of study grains. This visit will take up to 90 minutes to complete.
The intervention is a total of four weeks, during which participants will incorporate intact whole grains into their usual diet. Four weeks should be a sufficient to observe dietary changes. Daily during the study, participants will be prompted to complete a brief online survey to report the type and amount of study grains consumed over the course of the day.
Once per week during the intervention, participants will visit our laboratory, located in the Health Sciences Building on the WSU - Spokane Campus, for a 10-15-minute visit. During each visit, the investigators will provide one weeks' worth of study grains and review adherence to study protocols. At the end of the fourth week, participants will return to the laboratory for a final exit visit where study staff will measure participant weight and administer an exit survey and food frequency questionnaire. Our statistical power calculations indicate that forty-two participants included in this pilot study is sufficient for detecting an effect of whole grain intake between the two study conditions.

Measure Description |
Time Frame |
---|---|---|
Determine the effect of convenience on intake of intact cooked whole grains over a 4-week period
Time Frame: 4-week period
|
Participants in the ready-to-eat condition and dried condition will self report type of cooked whole grain and quantity of cooked whole grains consumed daily in REDCap.
The investigators will compare total intake of whole grains between the ready-to-eat and dried conditions as reported on daily REDCap checklists.
