Brief Summary:
The aim of the study is to investigate parameters of the lipid metabolism in plasma and feces of healthy subjects after a dietary supplementation of different dosages of milk phospholipids.

Condition or disease Intervention/treatment Phase
Healthy Dietary Supplement: Milk phospholipid Not Applicable

Detailed Description:

To date the mechanisms for the intestinal absorption of glycerophosphates and sphingolipids are not completely investigated. It is assumed, that sphingolipids and sterols compete for intestinal absorption. In addition it is unclear, if a dietary phospholipid supplementation may influence the phospholipid concentration in plasma.

To evaluate the effect of a dietary phospholipid supplementation 15 healthy female subjects received over 10 days daily 3 g of milk phospholipids stirred in a dairy product. During the following 10 days the subjects were supplemented with daily 6 g milk phospholipid. Finally, the subjects received over 10 days 6 g of the milk phospholipid in a dairy product and 2 g of plant sterols serving a commercial product.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 15 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Effect of a Milk Phospholipid Supplementation on the Lipid Metabolism in Healthy Volunteers
Study Start Date : May 2010
Actual Primary Completion Date : June 2010
Actual Study Completion Date : June 2010

Arm Intervention/treatment
Experimental: Phospholipid supplementation
Supplementation of milk phospholipid
Dietary Supplement: Milk phospholipid
During day 1 until 10 the subjects were supplemented with daily 3 g milk phospholipids, during the day 11 and 20 the supplementation was increased to daily 6 g, and during the day 21 and 30 the subjects received daily 6 g milk phospholipids and 2 g of plant sterols.

Primary Outcome Measures :
  1. Change in plasma phospholipid concentration [ Time Frame: after 0, 10, 20, and 30 days ]

    Total phospholipid concentration

    Individual phospholipid concentration (lyso phosphatidylcholine, phosphatidylcholine, sphingomyelin, phosphatidylethanolamine, phosphatidylinositol)

Secondary Outcome Measures :
  1. Plasma lipids [ Time Frame: after 0,10,20, and 30 days ]

    Fatty acid fraction (total fatty acid distribution, phospholipid fatty acid distribution)

    Cholesterol fraction (total cholesterol, LDL cholesterol, HDL cholesterol)

    Triacylglycerides fraction

  2. Fecal lipids [ Time Frame: after 0,10,20, and 30 days ]
    Fecal lipids (crude fat, total phospholipids, sterols, bile acids)
