Role of Cherry Consumption in Reducing Risk Factors for Chronic Inflammatory Diseases

Cardiovascular Diseases Clinical Trial

Official title: Role of Cherry Consumption in Reducing Risk Factors for Human Chronic Inflammatory Diseases

Status Completed

Clinical Trial Summary

The goal of this study is to examine if chronic cherry consumption will decrease lipid peroxidation and serum concentration of inflammatory markers in human subjects with elevated serum C reactive protein (CRP), and to examine the relationship between serum concentrations of CRP and polyphenols. The investigators hypothesize that cherry consumption will reduce serum concentration of inflammatory markers, including CRP, inflammatory cytokines and adhesion molecules.

Clinical Trial Description

The study will last a total of 64 days with three different metabolic periods. First 8 days will be period 1, when base line fasting blood samples will be collected on day 1 and 8. For the next 28 days (period 2 or intervention period) subjects will supplement their diets with 280 g/d of pitted Bing cherries by replacing an equivalent amount of carbohydrate calories. We will prefer that the subjects split the cherries into three equal portions and consume one with each meal; however, this will not be mandatory. Subjects will be asked to record all foods and drinks consumed for three 24-hr periods during the study. Fasting blood samples will be drawn on study days 22 and 36 (14 and 28 day after the start of cherry consumption). The third period of 28 days will be post-intervention, when the subjects will return to their normal diets without cherries. Post-intervention blood samples will be drawn on study day 64. All blood draws will follow a 12-hour fast. Blood samples will be processed within one hour of draw and the plasma stored frozen in different aliquots, until analysis. ;
