Current Projects

This study requires participation over a 4-week period. If you choose to participate, you will be provided with 1 serving per day of barley, buckwheat, and quinoa for each day of the week for at home consumption for 4 weeks. You will be provided information on how to cook and prepare these grains at home and given ideas of how to incorporate these whole grains into your regular diet.

At your first visit, we will confirm your eligibility for the study and have you review and sign the informed consent form. We will then collect weight and height measurements, randomize you to either the ready-to-eat or dried condition, and provide education on the benefits of whole grains, recommended intake of whole grains, how to include whole grains in your diet, and how to prepare the study grains. You will then be provided a link to complete a questionnaire about your eating habits. Lastly, you will be sent home with 7 days of study grains. This visit will take up to 90 minutes to complete.

Once a week, you will visit our lab to pick up more study grains. You will either receive dried grains in Ziplock baggies or receive a cooler packed with frozen ready-to-eat grains. Grains are eaten over the course of 7 days and an online survey will be completed daily.

Each day, you will be asked to measure how much of the study grains you ate. At the end of each day, we will send you a survey asking questions about which study grains you consumed and how much of each study grain you ate throughout the day.

You will also have an exit visit at the end of the 4 weeks where you will have your weight measured, complete a short exit survey, and complete a questionnaire about your eating habits.

We are looking for individuals who meet the following criteria:

• 19 years old or older
• Able to communicate in written and spoken English
• Not following a restricted diet
• Involved in home food preparation
• Daily access to working internet
• Daily access to working microwave, stove, refrigerator, and freezer
• English fluency

Individuals with the following characteristics will not be eligible to participate in the study:

• Dietary restrictions, including allergy/intolerance
• Latex allergy
• Following a diet to increase or decrease body weight
• Taking medication that promotes weight loss
• Use of nicotine, marijuana, or illicit drugs
• Pregnant, planning to become pregnant, or breastfeeding
• Inability to comprehend the nature of the study instructions
• No access to the internet
• Planning to leave the Spokane area during the study
• Not fluent in the English language

In order to find out whether you are a good fit with our study, we ask you to please fill out the online screening survey. After reviewing your results, we may invite you to our lab for a screening session to determine further eligibility that may take up to 90 minutes. Not everyone who comes to the screening will be eligible for the study. Information from your screening questionnaires will be permanently unlinked from your identity after eligibility has been determined.

You will be paid $100 in the form of a personal check upon completing all study protocols:

• One online screening survey (10 min)
• One in-person screening session (up to 90min)
• Incorporating the study grains into your diet for 4 concurrent weeks
• Completing brief daily online survey
• Coming to the lab once per week to pick-up additional study grains
• Completing the exit visit (up to 75 minutes)

If you complete less than 4 weeks, we cannot pay you. Likewise, if you do not complete all the study-related procedures including eating the study-provided grains and do not complete the daily surveys, we cannot pay you. This is due to the high cost of the trial. Additionally, we cannot use data from less than 4 weeks.

Please note: The screening sessions may determine that the study design is not suitable for you. There will be no payment for attending this screening session. If you are eligible for compensation at the end of the study, a personal check will be mailed to you directly from WSU fiscal services upon completion.
