"Let food be thy medicine and medicine be thy food." -Hippocrates

The Functional Foods & Human Health Laboratory in the Department of Food Science and Human Nutrition at Colorado State University is seeking volunteers to participate in a study investigating whether acute and chronic consumption of red beetroot juice can improve adverse cardiovascular and metabolic responses to eating a high-fat meal.

Who can participate?
- Healthy men and postmenopausal women aged 40-65 years with a body mass index (BMI) between 25-40 kg/m2
- Exclusion criteria apply and will be evaluated through a phone and in-person screening

Benefits
- Red beetroot juice supplementation
- Measures of blood sugar control, fat metabolism, blood pressure, and cardiovascular function

What is involved?
Participants will be asked to consume four different supplements daily for 1-month (placebo, placebo + potassium nitrate, red beetroot juice, and nitrate-free red beetroot juice), each separated by a 1-month break, and consume a high-fat meal on laboratory testing days. Participants will complete initial screening tests and qualified participants will undergo orientation to cardiovascular measurements, cardiovascular testing, and provision of multiple blood, urine, and saliva samples. All food and supplements will be provided.

Enrollment in this study is ongoing. The entire study will last approximately 8 months and involvement will consist of nine visits over this 8-month period. Participants will receive financial compensation of up to $300 for their time spent in the laboratory. The study will take place on the CSU campus in the Department of Food Science and Human Nutrition, in the Medical Nutrition Laboratory, Room 139 Gifford Building.

The goals of the Functional Foods & Human Health Laboratory are to identify and critically examine functional foods, bioactive compounds, dietary supplements, and other dietary interventions that can effectively prevent and/or improve both established and emerging risk factors for chronic diseases associated with aging such as cardiovascular disease in high-risk populations. The Functional Foods & Human Health Laboratory is located in the Department of Food Science and Human Nutrition, in the College of Health and Human Sciences at CSU.

This research study has been approved by CSU's Institutional Review Board, Protocol # 16-6495HH.
