Welcome
Thank you for your interest in the SCOPE Study!
SCOPE stands for the effects of soluble corn fiber consumption on cognitive function and gastrointestinal microbiota. The SCOPE study is a research project that is aiming to investigate the effects of daily consumption of a corn fiber supplement on various outcomes such as gut microbiome health and cognitive health. Contributing labs to this study are the Body Composition and Nutritional Neuroscience Laboratory and the Nutrition and Human Microbiome Lab.
This study will be completed over the course of 12-15 weeks inside and outside the laboratory at the University of Illinois Champaign-Urbana. We are looking for men and women between the ages of 45-75 years old to participate in our study.
