Evaluation of Milk Polar Lipids in Dyslipidemic Adults With Abdominal Obesity

August 11, 2026 updated by: Christopher Blesso, University of Connecticut

Evaluation of Milk Polar Lipids on Lipoprotein Metabolism, Inflammation, and Gut Microbiota in Dyslipidemic Adults With Abdominal Obesity

The major objective of this project is to examine whether daily consumption of milk polar lipids (MPLs) influences cardiometabolic risk factors.

Detailed Description

The investigators will conduct a randomized, double-blind, controlled, parallel, intervention study in dyslipidemic adults with abdominal obesity (n = 130). Participants will consume either a control dairy beverage (n = 65) or an MPL-rich dairy beverage (n = 65) for 8 weeks. The investigators plan to evaluate the following 4 specific objectives:

  1. Determine the effects of MPLs on serum lipid concentrations and other cardiometabolic risk factors.
  2. Evaluate the effects of MPLs on systemic biomarkers of low-grade inflammation.
  3. Examine the effects of MPLs on lipoprotein metabolism and lipoprotein particle characteristics.
  4. Evaluate the effects of MPLs on gut microbiota, gut permeability markers, and fecal lipids.
