The REACH Study (Ready-to-EAt meals for Cardiovascular Health)


The REACH (Ready-to-EAt meals and Cardiovascular Health) study is evaluating the effects of ready-to-eat meals on blood pressure and aims to compare how diets consisting of various ready-to-eat foods may have benefits for the regulation of blood pressure, an important risk factor for cardiovascular disease. The foods in this study are prepared by WSU food scientists in Pullman, Washington. All of the meals provided will fit into the Dietary Approaches to Stop Hypertension (DASH) diet pattern.


Enrollment beginning late summer 2022 at Washington State University’s Elson S. Floyd College of Medicine Campus in Spokane. Each study period is 5 consecutive weeks. Lab visits once per week on weekday mornings. Each visit will take 20-30 minutes.


This study requires participation over a 5-week period. You will be provided with lunch and dinner meals for each day and asked to consume all provided meals for 4-concurrent weeks. You will be provided information on the DASH guidelines and how to select your breakfast meals and snacks that will not be provided by the study.

At your first visit, we will confirm your eligibility for the study, and have you sign and review the informed consent form. You will also complete a questionnaire about your regular eating habits, and physical activity. We will collect weight, height, waist circumference, and blood pressure. Lastly, we will provide information on the DASH diet eating pattern. This baseline visit will take up to 120 minutes to complete.

Once a week, you will visit our lab to pick up food and have your weight and blood pressure measured. These visits will take 20-30 minutes.

Each day at home, you will be asked to measure your own blood pressure in the morning and evening. You will be provided with an at-home blood pressure monitor and cuff and given instructions on how to use it. At the end of each day, we will send you a survey asking about your blood pressure measurements, your appetite throughout the day, and your overall satisfaction with the provided meals. Lastly, you will have an exit visit at the end of the 4-concurrnet weeks where you will return your blood pressure monitor and any other study materials, we will measure your weight, blood pressure, and waist circumference and provide short exit survey. This visit will take 20-30 minutes.

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. This will be followed by an in-person screening session that will take up to 120 minutes to complete. 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 $300 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 120min)
  • Eating all provided meals and snacks for 4 concurrent weeks
  • Following the study-provided guidelines for breakfast and snacks each study day
  • Completing twice-daily blood pressure measurements and once daily appetite ratings
  • Coming to the lab once per week for blood pressure and weight measurement and food pick-up
  • Completing the exit visit

If you complete less than 5 weeks, we cannot pay you. Likewise, if you do not complete all of the study-related procedures including eating all of the study-provided meals and following the DASH guidelines for breakfasts and snacks, collecting and reporting twice-daily blood pressure measurements, and completing 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, you will be able to pick up your payment in person from study staff at your exit visit.
