Pilot study to determine whether daily consumption of blackraspberry powder (high in polyphenols) can reduce markers of inflammation and to determine whether genetics influence baseline levels of inflammatory markers as well as individual's response to polyphenols. A total of 10 males participated in this cross-over study.

Condition Intervention Phase
Dietary Supplement: Blackraspberry Slurry
Phase 1
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Inflammation, Polyphenols, and Genetics: A Pilot Study in Overweight and Obese Adult Males to Determine Whether Black-Raspberry Consumption Affects Markers of Inflammation in Study Participants Fed a High-Fat, High-Calorie Challenge Meal

Further study details as provided by Ohio State University:

Primary Outcome Measures:
  • Serum IL-6 [ Time Frame: acute (0-12 hours) after inflammation-causing challenge meal ]
    Area Under the time-concentration Curve (AUC) of IL-6

Enrollment: 10
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: Blackraspberry slurry, washout, water
Blackraspberry slurry daily x 5 days, 2 day washout, 8 oz. water daily x 5 days
Dietary Supplement: Blackraspberry Slurry
Blackraspberry slurry is 45 g blackraspberry powder mixed in 8oz. water. This is equivalent to 450 g fresh black raspberries.
Experimental: Water, washout, Blackraspberry slurry
8 oz. water daily x 5 days, 2 day washout, Blackraspberry slurry daily x 5 days
Dietary Supplement: Blackraspberry Slurry
Blackraspberry slurry is 45 g blackraspberry powder mixed in 8oz. water. This is equivalent to 450 g fresh black raspberries.

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.
