Older Adults Wanted for Blackberry Study

We want to know how consuming freeze-dried blackberry powder (equivalent to 2 cups fresh berries) every day for 12 weeks may impact learning and memory and the gut microbiome.

We are looking for men and women aged 55 years and older who are not currently eating more than 2 cups of berries per week, do not have any memory or learning disorders, and do not take medications that affect focus and concentration. Additional screening criteria apply.

This study involves giving blood, urine, and fecal samples, taking learning and memory tests, 5 visits to OSU (Corvallis, Oregon), and lasts about 4 months. If you take part, you will receive up to $100.

For more information and to see if you qualify to participate, see this page on the blackberry research study.
