Older Adults Wanted for Walnut Study

We want to know how consuming 1.5 oz. of walnuts (about 0.5 cup) every day for 12 weeks may impact learning and memory and the gut microbiome. 

We are looking for volunteers aged 55 years and older who 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), and lasts 14 weeks.  You will receive $300 upon completion.
