The purpose of this study conducted at Stanford University is to investigate if the dietary fiber correlates with cognitive function and other biomarkers. Active participation will take approximately 3-5 hours total over the course of 1 year. We will ask you to do the following tests for 3 times (every 3-4 month): 1. Complete a 2 weeks food log as well as a food frequency questionnaire; 2. Complete a battery of online cognitive tests; 3. Collect a drop of blood from a finger prick (called microsampling collection) as well as stool samples; we will mail the kits to your place to let do at-home sample collection; 4. Optional: we also want to collect fitness tracker data, if you own a device already, such as Fitbit or Apple watch.


There are 3 data collection time points: at beginning, 6 months, and 1 year. These include: • Online cognitive tests (duration of about 12 minutes). • Filling diet records for 2 weeks and 1 diet questionnaire. • Self-collected blood microsamples and stool samples. All the testing will be done from your home with no need of physical visits.
