Precision Health study Focusing on the dietary glycemic index of carbohydrates
A Tulane University Study
Objective is to learn about how changing daily carbohydrate intake can affect blood sugar and metabolism, in particular after meals.
Participation in the study requires 3 visits to the study site in downtown New Orleans within a 2-week window.
Participants will be recruited in the New Orleans Metro area.
Be a part of this important study that can advance our understanding of carbohydrates and effects on blood sugar and metabolism.
Visit One
Eligibility is determined, Continuous Glucose Monitor (CGM) applied to the back of the arm, actigraphy watch to measure movement and sleep applied.
Visit Two
Participants randomized into 1 of 2 diets – low glycemic or high glycemic – and given three full days’ worth of food to consume.
Visit Three
Participant’s final visit, CGM and actigraphy watch returned.

Health Benefits
The CGM report in particular shows our participants how their blood sugar fluctuates throughout the course of the day, responding to particular foods or activities.
Health Outcomes
The more we learn about the effects of carbohydrates and blood sugar the better we can manage positive health outcomes.
Health Education
Health Education is always a component of post study outreach to inform the health providers and community.
