Primary Outcome Measures:
  • Inflammatory biomarkers (CRP, TNF-alpha, and IL-6) [ Time Frame: acute (0-12 hours) after inflammation-causing challenge meal ] [ Designated as safety issue: No ]

Enrollment: 12
Study Start Date: March 2012
Study Completion Date: May 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Black-raspberry powder Dietary Supplement: Black-raspberry powder
Black-raspberry powder (45g) equivalent to about 450 g fresh black raspberries
No Intervention: No intervention

Detailed Description:

A high-fat, high-calorie challenge meal is administered to induce an inflammatory response in overweight and obese adult males. Serum levels of CRP, TNF-alpha, and IL-6 are measured prior to the challenge meal and at various times (1,2,4,8, and 12 hours) after the challenge meal. The challenge meal is given once without intervention and once after 5 daily doses of concentrated black-raspberry powder mixed in water.
