Fructose Liver Fat Study

The UNC Nutrition Research Institute is recruiting Caucasian women ages 18-40 with no history of alcohol abuse for a study to identify genetic and dietary factors that affect the risk for non-alcoholic fatty liver disease. On the first visit participants will provide saliva samples. Selected participants will return to undergo an acute, and a 2-week oral fructose challenge for a total of three visits. Each visit, participants will provide blood, urine, and stool samples, as well as fill out a questionnaire. Participants will be compensated. Visit the NRI website for more details and to enroll.

Choline Status Study

Study Purpose: The purpose of this study is to determine which biomarkers in the blood most accurately reflect choline status. Choline is an important nutrient in human diet.

What participants will do: To do this, volunteer subjects will be placed on a low choline diet for two weeks, followed by a two week washout, and then another two weeks on a diet containing adequate choline levels. We will provide all your meals for the 4 weeks (28 days) spent on the low choline and adequate choline diets, and you must not eat or drink any other foods during those weeks. We will take blood and urine samples at various times throughout the study to examine various markers and determine how they are changed by dietary choline levels.

Recruiting: Healthy males and females between ages of 17-70 years of age.
To participate your weight must be between 132-177 lbs.

Compensation: Eligible participants will be compensated for their time and payments will be reported to the IRS as income unless you choose to participate without compensation. The amount is $750 for completing the study

Diet and the Gut Microbiome Study

Study Purpose: The purpose of this study is to identify individual differences in metabolite production after the intake of specific foods, which provide important nutrients for the body.

What participants will do: Study activities will occur over 4 days. Volunteer subjects will consume a standard diet for the first two days of the study. It is important that participants only eat foods provided by the study for these two days. On the first study day, participants will come to the Nutrition Research Institute (NRI) to receive their study materials, complete study surveys, and provide a saliva sample. We estimate that this visit will take about two hours. Participants will complete study activities in their home for the remainder of day one and day two. On the third study day, participants will consume dietary supplements in the morning along with a standard diet for the day, and collect all urine over the following 24-hours. On day four of the study, participants will return their urine samples to the NRI. Participants will also provide a stool sample.

Recruiting: Healthy males and females between ages of 18-70 years of age. Exclusions: No smoking, known food allergies, history of chronic medical illness, antibiotic use in last three months

Compensation: Eligible participants will be compensated for their time. The amount is $200 for completing the study.

Project Baseline

Project Baseline is a long-term quest to map human health.  The Project Baseline study, launched in 2017, is the first initiative of Project Baseline and is a collaboration among teams at Verily, Duke University School of Medicine, Stanford Medicine, and Google.

Compensation: Offered throughout the study, which will follow participants for at least four years.

Interested in enrolling? To learn more and consider joining this exciting endeavor, visit or call 855-5-BASELINE (855-522-7354).

How long will the Project Baseline study last? How many people will enroll?

The Project Baseline study is an observational study that will collect, organize, and analyze broad health data from approximately 10,000 participants over the course of at least four years.

Who can participate in the Project Baseline study?

Participants must be at least 18 years old, residents of the United States, able to speak and read English or Spanish, and not severely allergic to nickel or metal jewelry.

What is the Project Baseline study trying to find out?

The study is designed to develop a well-defined reference, or “baseline,” of good health, as well as a rich data platform that may be used to better understand the transition from health to disease. Participants will join together with a team of experts from across academia, medicine, science, technology, engineering, and design to better understand how health can change over time. Participants will be asked to visit a study site up to four times yearly, test new technologies and wearable devices daily, and participate in interactive surveys and diaries by using a smartphone, computer, or call center. Data collected will include clinical, imaging, self-reported, physical, environmental, behavioral, sensor, molecular, genetic, and other health-related measurements. Biospecimens collected will include blood and saliva, among others.
