LiBra: This study examines the relationship among diet, physical health, and cognitive performance in children ages 8 to 13 years. Participation involves 2 visits to Freer Hall and possibly 3 visits to Beckman Institute. Measures will include health behaviors such as diet and physical activity, weight status, brain imaging, and a blood draw. Participants will receive up to $300. IRB #19811
SHELL Study: This study examines the relationships among dietary intake, retinal health, and cognition in children ages 7-12 years. Participation involves 3 visits to complete paper and pencil tests, an exercise test, a bone density scan, eye tests, and computer-based cognitive tasks. Participants may also qualify to receive daily snacks for 4 weeks and have 3 follow-up visits. Participants will receive $100 after completion of the first 3 visits and, if eligible to participate, another $100 after the last 3 visits. IRB #18305
SNACKing Study: This study investigates the relationship among diet, gut health, and metabolic health in adults between the ages of 30-60 years. Participation consists of a 12-week period where participants consume a pre-packaged snack twice per day. Participants are asked to visit the lab for 3 sessions to complete questionnaires, body composition scans, liver ultrasounds, and blood draws. Six stool samples will also be collected. Participants will receive $50 after the first two visits and $250 upon completion. IRB #20154
HAPPIMOMs: Health Assessments Pre and Postpartum Involving Macular pigments, Obesity/Overweight, and Microbiome Study. HAPPIMOMs examines the relationship among aspects of nutrition, gut health, and weight changes during and after pregnancy. Women in any stage of pregnancy or those who have recently given birth (<12 weeks prior) can participate. Sessions last about 1.5 hours each and include surveys and several non-invasive measurements. Participants will receive up to $150. IRB #19694
BAT Kids: Behavioral Associations with Thinking in Kids is a study for children ages 4-5 years that is investigating the relationship between early life nutrition and thinking ability.
EPOCH: Evidence-based dietary strategies provide behavioral means of mitigating the effects of obesity on physical and cognitive function in adults ages 25-45 years. The EPOCH study aims to investigate effects of a fermented dairy beverage consumption and a lactose-free dairy beverage with added dietary prebiotic fiber on changes in behavioral and biological measures of cognition and stress among obese adults.
