NIH’s Nutrition for Precision Health study featured on CBS Sunday Morning
The National Institutes of Health’s study Nutrition for Precision Health, powered by the All of Us Research Program, was highlighted on CBS Sunday Morning as a key driver of innovation in nutrition research. The study, led by the NIH’s Common Fund, All of Us, and Office of Nutrition Research is the largest precision nutrition research effort of its kind. It aims to enroll 8,000 or more participants from diverse backgrounds and learn more about how our bodies respond differently to food. The news segment followed the experience of an All of Us participant as she takes part in the groundbreaking nutrition study, eating provided meals and sharing data and samples for analysis. The episode also highlights the novel methods and technology the study team is using to examine different factors that influence nutrition and health, including tests measuring participants’ resting metabolic rate, use of sensors to record food intake in addition to food diaries and an innovative microbiome collection device.

ABC News’ Becky Worley joins research study that could help millions of others
May 3, 2024 by Becky Worley (Good Morning America)
Becky Worley is an ABC News correspondent based in California. Here, she documents her experience as a participant in the All of Us Research Program, a National Institutes of Health project that aims to study more than 1 million people from all backgrounds. It started like most "Good Morning America" assignments, an idea from our Med Unit about a new study being conducted by the National Institutes of Health. They pitched the "All of Us" study to our editorial group, and I was asked to bring the story to air. But in the end, it was unlike any story I've ever done. Read more >
Current Clinical Trials
| Study Type | Title/Purpose | Principal Investigators |
|---|---|---|
| CURRENT | ||
| Interventional | Nutrition for Precision Health The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are:
There are 3 Modules participants may take part in:
Status: Recruitment Ongoing | Zhaoping Li, MD, PhD For more information contact Molica Arana Clinical Study Coordinator 310-206-8292 |
| Interventional | Effect of Metformin ER with Hypocaloric Diet on Weight Loss in Overweight/Obese Patients with Increased Waist Circumference Metformin is a drug used to treat patients with diabetes. The aim of this study is to examine the effect of Metformin along with a low-calorie diet on obese and/or overweight adults with an increased waist measurement. In addition, the study also aims to look at the effect of the drug vs. placebo on quality of life and physical activity. During this study, your participation will last up to 26 weeks (including screen) for a total of 8 clinic visits. You will undergo a total of 5 blood draws, blood samples taken at screen, baseline and weeks 8, 16 and 24. You will also be asked to take the study drug or placebo during the duration of this study. You will be asked to take one capsule a day for two weeks, then increase to 2 capsules a day for the rest of the study at approximately the same time each day.

| Interventional | Effect of Mango Consumption on Skin Health The purpose of this study is to determine if the daily consumption of one cup of mango compared to 1 oz of pretzel snacks for 12 weeks will 1) enhance antioxidant defense of your skin by assessing the minimal dose of ultraviolet (UV) B light that irritates your skin (reddening-erythema); 2) enhance the ability of your skin to stretch (elasticity), skin moisture (hydration), skin texture, oil secretion (sebum) and reddening (erythema); and 3) measure gene expression of genes involved in oxidative damage (caused by oxygen radicals created by UVB), collagen (structural protein) formation and inflammation (a condition where skin becomes reddened, swollen, hot and painful) in skin cell samples collected by skin tape stripping and blood markers for oxidative stress and inflammation. Status: Open for Enrollment See Flyer: English | Zhaoping Li, MD, PhD For more information contact Jeraldine Guzman Clinical Study Coordinator 310-206-8292 |
| Interventional | Effects of Diets on Memory in subjects with Long-COVID Symptoms The purpose of this study is to determine the effect of daily consumption of two ounces of walnuts compared to habitual diet for 12 weeks in individuals with long-COVID on 1) cognition, fatigue and mood symptoms; 2) clinical parameters such as weight, body composition and inflammatory blood marker, dietary quality and quality of life; and 3) the feasibility of the study design. Status: Recruitment Closed See Flyer: English | Zhaoping Li, MD, PhD For more information contact Hila Zelicha Clinical Study Coordinator 310-206-8292 |
| Interventional | Effect of Daily Mixed Spice Consumption on Memory The purpose of this study is to determine if the daily consumption of mixed spice for 6 months leads to improved cognition, fatigue, sleep quality, and mood symptoms and explore the mechanism of how spice consumption affects cognitive, fatigue, sleep quality, and mood symptoms. Your study participation will be expected for 6 months (see page 3 for further details).

| Interventional | A study to compare the effectiveness of health interventions between African American and Non-Hispanic white men undergoing hormonal prostate cancer therapy to lower cardiovascular risks. The purpose of this study is to determine if dietary intervention and exercise will help you to lose weight and improve your heart health. Previous research has shown an increase in risk factors for heart disease in men undergoing androgen deprivation therapy (ADT). ADT is a widely used treatment for men with prostate cancer disease to lower the male hormone, androgen, to stop it from causing prostate cancer cell growth. We plan to study the effectiveness of the intervention between African-Americans and non-Hispanic white men. This study will be conducted in 2 phases (3 months each), phase I: habitual diet where you will continue with your regular diet and exercise routine and phase II: dietary intervention and exercise.

Participants must be willing to actively participate in the hands-on classes (may be in-person or virtual), fill out a number of survey questionnaires, complete 4 blood draws, 2 urine samples, along with physical assessments (weight, blood pressure, etc) and 2 stool collections. Status: Closed for Enrollment | Zhaoping Li, MD, PhD |
| Interventional | Impact of Anti-Inflammatory Whole-Food Diet in Crohn's Disease and Predicting Response to Therapy Diet has a strong influence on the composition of the bacteria in our gut and can be important if we want to modify CD symptoms and activity. There is still a great gap in research as to which diets and what diet therapy would be most effective. Previous studies have shown that certain diets were more effective for managing CD symptoms. The aim of the study is to test two different diets and their effect on CD. This is a randomized, single-blind, controlled trial. Status: Closed | Zhaoping Li, MD, PhD
