About
Phase 1 of this study involves determining how consumption of dairy fat fractions rich in milk fat globule membrane influences postprandial inflammation in participants with metabolic syndrome or obesity during a high dietary fat challenge in a six-hour period.
Full description
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.
