Participants needed for a research study

From: Department of Human Nutrition, Foods, and Exercise

Research study on ultra-processed food consumption, gut microbiota, and glucose homeostasis in mid-life adults. We are conducting a study (IRB Protocol # 21-974) to learn if consuming processed or unprocessed foods has any impact on blood glucose levels or cardiovascular health. Participants will be provided all meals for 8 weeks, and consume either a diet high or low in processed foods. You may be eligible to participate if you are 45-65 years old.

The study will include coming to the lab for breakfast each day for eight weeks (Monday-Saturday) and taking your remaining food home for the day. Food for Sunday will be provided on Saturdays. Assessments include DEXA scans, three oral glucose tolerance tests, two 48-hour urine collections, two 3-day stool collections, and wearing a glucose monitor and a physical activity monitor for one week at the beginning and end of the study.

This study involves 50 visits to Virginia Tech's Blacksburg campus over 9 weeks. Total time commitment will be about 35 hours. Participants will be compensated a total of $500 upon successful completion of all study visits.
