Study start date: August 1, 2013

Actual date on which the first participant was enrolled.

Phase 1 is a randomized crossover study designed to determine how inclusion of dairy fractions rich in milk fat globule membrane (MFGM) to shakes rich in dairy or palm fat influence postprandial inflammation. Participants who have 2 or more risk factors of metabolic syndrome or BMI ≥ 30 will consume four shakes on separate days. The four shakes are: high dairy fat, high dairy fat + MFGM, high palm fat, high palm fat + MFGM. Eligible participants will arrive to the Western Human Nutrition Research Center (WHNRC) at the University of California (UC) Davis campus on the morning of each test day after a 10-12-hr overnight fast. Upon arrival participants will fill out a questionnaire about their dietary and medication intakes and physical activity for the past 72 hours to ensure compliance. Compliant participants' weight and blood pressure will be measured and a fasting blood draw will be taken before participants consume their test meal. Participants will only consume this test meal and water freely for the duration of the test day. Blood will be drawn serially at 1, 3 and 6 hours postprandially. Participants will be tested on the additional three arms on three different spaced apart by two weeks. On the third or fourth test day, participants' body composition and bone mineral density will be measured by dual x-ray absorptiometry.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

38 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Treatment Groups
Study Objectives

4 intervention groups are designated in this study

This study does not include a placebo group 

Treatment Groups

Group I

Active Comparator
The amount of calories in the shake will be equivalent to 30% of each participant's calculated energy expenditure. The macronutrient composition of the shake as a percent of energy will be: 45% fat, 40% carbohydrate and 15% protein. The shake will contain palm fat, frozen fruit, glucose polymer, and protein powder.

Group II

Experimental
The amount of calories in the shake will be equivalent to 30% of each participant's calculated energy expenditure. The macronutrient composition of the shake as a percent of energy will be: 45% fat, 40% carbohydrate and 15% protein. The shake will contain palm fat, frozen fruit, glucose polymer, and BPC50, a dairy fraction rich in milk fat globule membrane proteins and phospholipids. Fifty percent of the shake's fat will be derived from BPC50.

Group III

Active Comparator
The amount of calories in the shake will be equivalent to 30% of each participant's calculated energy expenditure. The macronutrient composition of the shake as a percent of energy will be: 45% fat, 40% carbohydrate and 15% protein. The shake will contain whipping cream, frozen fruit, glucose polymer, and protein powder.

Group IV

Experimental
The amount of calories in the shake will be equivalent to 30% of each participant's calculated energy expenditure. The macronutrient composition of the shake as a percent of energy will be: 45% fat, 40% carbohydrate and 15% protein. The shake will contain whipping cream, frozen fruit, glucose polymer, and BPC50, a dairy fraction rich in milk fat globule membrane proteins and phospholipids. Fifty percent of the shake's fat will be derived from BPC50.
