A Dietary Intervention to Modify Breast Milk Content in Obese Lactating Women

September 29, 2025 updated by: Arkansas Children's Hospital Research Institute
This study is a nutrition research study designed to look at how healthy meals can influence the content of breast milk. Moms will be provided with meals that follow a Mediterranean diet pattern for 4 weeks. The goal of the study is to see if breast milk content changes over the 4 week period. The infants of the moms will also be included in the study to measure any changes in growth.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in breast milk fat concentration by mid-infrared spectroscopy
Time Frame: The change in breast milk fat concentration will be assessed by mid-infrared spectroscopy by measuring the concentration before the participants begin the dietary intervention, 2 weeks into the intervention, and at the end of the 4-week intervention.
The primary aim is to test whether the dietary intervention modifies the breast milk fat concentration of obese mothers.
The change in breast milk fat concentration will be assessed by mid-infrared spectroscopy by measuring the concentration before the participants begin the dietary intervention, 2 weeks into the intervention, and at the end of the 4-week intervention.
