Nutrition clinical trials at University of California Health

6 in progress, 3 open to eligible people

Showing trials for

  • Dietary Intervention to Improve Kidney Transplant Outcomes

    open to eligible people ages 18 years and up

    Randomized controlled trial of a curriculum intervention teaching patients to eat a whole-food plant-based dietary pattern versus standard of care in kidney transplant recipients within the first few months of transplant

  • Enhanced SUPport for Initiation and paRticipation in a FOOD is Medicine Program

    open to eligible people ages 18 years and up

    The purpose of this research is to see if offering more navigation and text-message support will help increase participation and engagement in a Food is Medicine program. The study will recruit people currently participating in cardiac rehabilitation. People will be randomly assigned to 1 of 4 study groups: navigation, text-messaging, both, or neither. People will complete surveys at the start of the study and after 3 months. After 3 months, we will compare how many Food is Medicine meals or groceries people in each group received.

  • Nutrition for Precision Health, Powered by the All of Us

    open to eligible people ages 18 years and up

    The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are: - How does varying foods and eating patterns impact one's biological and physiological responses? - In what ways can novel dietary assessment measures be used to improve dietary assessments and to prescribe assessments to people in future research with increased precision? - Can artificial intelligence and machine learning techniques be combined to prescribe foods and eating patterns to individuals for optimization of their health? There are 3 Modules participants may take part in: - Module 1- A participant's dietary intake and accompanying nutritional status, biological and other measures will be observed over 10 days, as well as physiological responses to a liquid mixed meal tolerance test will be measured. - Module 2- Participants will undergo three controlled dietary interventions provided for 14-days each and separated by washout periods of at least 14 days. Physiological responses following a diet-specific meal test will be measured. - Module 3- Participants will undergo the same three dietary interventions during the same 14 day periods as Module 2 while being studied in-residence. Physiological responses following a liquid mixed meal tolerance test and a diet-specific meal test will be measured.

  • Front-of-package Nutrient Labels

    Sorry, accepting new patients by invitation only

    This study aims to compare different front-of-package label designs, using two schemes: (1) High In and (2) Nutrition Info with each scheme having (1) a version with colors (i.e., green, yellow, and/or red) indicating level of nutrient content and (2) a black-and-white version. Additionally the Nutrition Info scheme will have a version that includes the percent Daily Value in black and white. Labels will be compared against a no-label control and one another.

  • Comparing Front-of-package Nutrient Labels

    Sorry, not yet accepting patients

    The goal of this study is to compare front-of-package labels to a no-label control and to one another: 1.) FDA's Nutrition Info with %DV, 2.) Nutrition Info with red "high", 3.) FDA's High In, 4.) multiple High In labels-one for each nutrient and 5.) a no-label control. Primary outcomes include 1.) correct identification of foods and beverages with the healthiest and least healthy overall nutrient profiles, 2.) perceived healthfulness of products low in two nutrients of concern, and 3.) correct identification of foods and beverages as high in saturated fat, sodium, and added sugars.

  • Added-sugar Menu Labels

    Sorry, accepting new patients by invitation only

    To compare two added-sugar menu label--(1) black, icon-only, 150% of the menu text height and (2) red, icon-plus-text, 100% of the menu text height--to a no-label control on grams of added sugar ordered using two different added-sugar labeling thresholds: (1) ≥50% of Daily Value for added sugar (equivalent to ≥25g) and (2) ≥100% of Daily Value for added sugar (equivalent to ≥50g)
