Het meten van resultaten van totale melkinname op lipide en GControl (GOT MILC)

30 september 2026 bijgewerkt door: University of California, San Francisco

Atherosclerotic cardiovascular disease remains the leading cause of death for adults in the United States. The cardiovascular impact of milk consumption remains a matter of long-standing scientific debate. Current guidelines for Americans recommend three daily servings of fat-free or low-fat (1%) dairy over full-fat options due to concerns that saturated fat may increase cardiovascular risk. Yet, the literature does not consistently support non-fat dairy as superior to high-fat dairy for reducing cardiometabolic risk. Identifying the comparative health benefits of non-fat versus high-fat dairy milk would be immediately applicable to patients who seek cardiovascular care. In this randomized, case-crossover trial, the investigators seek to efficiently assess the association between high-fat versus non-fat dairy milk consumption and insulin resistance. Utilizing the Eureka Platform, participants will be randomized to limit their liquid milk consumption to whole milk followed by skim milk (or vice versa), measuring the effect of milk fat content on glycemic index and lipid profile.

Studie Overzicht

Gedetailleerde beschrijving

The study is designed as an N of 1 randomized trial, where each participant will be randomized to consume high-fat versus non-fat dairy milk then crossover to the alternate condition over two consecutive two-month periods. After two and four months, participants will have lab tests performed, including hemoglobin A1c (HbA1c) and fasting lipids. Throughout the study, participants will be instructed to continuously wear a wrist-worn fitness tracker, use a Bluetooth-enabled scale and blood pressure monitor to trend weight and blood pressure weekly, and utilize the Eureka mobile application for self-monitoring of dairy milk consumption, diet, lifestyle, and physical activity. Aside from study-related dairy milk instructions, all other aspects of diet will remain constant throughout study participation. The study seeks to elucidate the relationship between dairy milk consumption and overall health. A total of 110 participants will be enrolled for participation in this clinical trial.

Wapens en interventies

Deelnemersgroep / Arm
Interventie / Behandeling
Experimenteel: Whole Milk-Skim Milk

Participants randomized to the whole milk-skim milk treatment sequence will be instructed to limit their liquid milk consumption to only whole milk during the first two months of the study (Month 1-2), followed by only non-fat milk during the final two months of the study (Month 3-4). Using an N-of-1 strategy delivered by the National Institutes of Health (NIH)-funded, University of California, San Francisco (UCSF)-run Eureka platform utilizing a mobile smartphone-based application, subjects will be instructed weekly via app and text-based messaging on the type of liquid milk (whole or non-fat) to consume.

If randomized to the whole milk-skim milk treatment sequence, participants will be instructed to restrict their liquid milk consumption to only whole milk for the first 2 months and to only skim milk for the last 2 months of the enrollment period. Participants will receive weekly app and text-based message reminders of their randomization assignments.

Experimenteel: Skim Milk-Whole Milk

Participants randomized to the skim milk-whole milk treatment sequence will be instructed to limit their liquid milk consumption to only non-fat milk during the first two months of the study (Month 1-2), followed by only whole-fat milk during the final two months of the study (Month 3-4). Using an N-of-1 strategy delivered by the National Institutes of Health (NIH)-funded, University of California, San Francisco (UCSF)-run Eureka platform utilizing a mobile smartphone-based application, subjects will be instructed weekly via app and text-based messaging on the type of liquid milk (whole or non-fat) to consume.

If randomized to the skim milk-whole milk treatment sequence, participants will be instructed to restrict their liquid milk consumption to only skim milk for the first 2 months and to only whole milk for the last 2 months of the enrollment period. Participants will receive weekly app and text-based message reminders of their randomization assignments.
