Who can participate?
- Men between the ages of 45-70 years
- Slightly elevated blood pressure or stage 1-hypertension
- Systolic blood pressure (top number) between 120 and 140 mmHg, and/or diastolic blood pressure (bottom number) between 80 and 89 mmHg
- Other inclusion and exclusion criteria apply and will be evaluated through phone and in-person screening
- Measures of blood pressure and cardiovascular health, including vascular (blood vessel) function
- Monetary compensation up to $200 for participation
What is involved?
Participants will be asked to consume a randomly assigned treatment daily for 12 weeks (either 22 g freeze-dried wild blueberry powder, or 22 g placebo powder). Participants will complete initial screening tests and qualified participants will undergo cardiovascular testing and provision of samples such as blood and urine. Involvement in the study will last 12 weeks and involvement will consist of 4 test visits over this period (visits last between 45 minutes and 1.5 hours). Participants will receive financial compensation of up to $200 for their time. The study will take place on the CSU campus in the Department of Food Science and Human Nutrition.
