About this trial

The goal of this clinical trial is to find out if dairy is a good source of choline compared to eggs. The main questions it aims to answer are:

* How the body uses choline; and, * What effect WPPC has on choline metabolism.

Researchers will compare Whey Protein Phospholipid Concentrate (WPPC) to whole egg powder to see if WPPC is as effective as eggs.

Participants will drink a chocolate-flavored smoothie mixed with either WPPC or whole egg powder.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Ages between 51 and 70

Trial outcomes

Primary outcomes

1

Change in circulating choline

Circulating choline will be measured by UHPLC-HRMS/MS

Time frame
Baseline to 10 days

Secondary outcomes

1

Change in co-factors in circulating choline

Co-factors in the circulation will be measured by ultrahigh performance liquid chromatography coupled with high resolution tandem mass spectrometry (UHPLC-HRMS/MS).

Time frame
Baseline to 10 days
2

Change in high-sensitivity C-reactive protein (hs-CRP)

Safety biomarker Hs-CRP will be measured using immunoturbidimetry.

Time frame
Baseline to 10 days
3

Change in circulating choline metabolites

Metabolites will be measured by UHPLC-HRMS/MS.

Time frame
Baseline to 10 days
4

Change in 8-hydroxydeoxyguanosine

The safety biomarker 8-hydroxydeoxyguanosine (8-OHDG) will be measured using enzyme-linked immunosorbent assay (ELISA).

Time frame
Baseline to 10 days
