About

In this study, the investigators recruited at-risk individuals (n=10) who were overweight (25.0-29.9 kg/m2) and obese (> 30.0 kg/m2) and likely to exhibit one or more conditions associated with Metabolic Syndrome (MetS). In this 10-week placebo-controlled 2 x 2 crossover dietary intervention, the investigators randomized participants (n=10) to consume 240 mL (8 ounces) daily of either placebo (artificial cherry-flavored, anthocyanin-free beverage) or authentic TCJ for 4 weeks, followed by a 2-week washout period, then consumption of the alternate beverage for 4 weeks. In this study, the investigators determined the effect of TCJ in at-risk participants on markers of inflammation, glycemia, and lipidemia.

Full description

In this study, the investigators recruited at-risk individuals (n=10) who were overweight (25.0-29.9 kg/m2) and obese (> 30.0 kg/m2) and likely to exhibit one or more conditions associated with MetS. Participants were >18 years of age, not pregnant, not diabetic, with no unresolved infections or diseases (diabetes, CVD, IBD, cancer and liver disease), and nonsmokers. Histories of medication and dietary supplement use were collected and those taking anti-inflammatory or lipid-lowering medications were excluded. After enrollment, subjects were randomly assigned to consume daily either 240 mL (8 ounces) of authentic TCJ (R.W. Knudsen, Chico, CA) or a placebo beverage (commercial fruit punch; Great Value, Bentonville, AR) for 4 weeks. After a 2-week washout period, participants consumed the alternate beverage for 4 weeks in this 10-week 2x2 crossover, placebo-controlled dietary intervention. Subsequently, the investigators determined the effect of TCJ in at-risk participants on markers of lipidemia (HDL, LDL, triglycerides, VLDL, total cholesterol), glycemia (fasting insulin and glucose, HOMA, QUICKI, McAuley indirect indices), and inflammation (hsCRP, TNF-alpha, and ESR).

Inclusion criteria

This study was a 12-week 2 x 2 crossover, randomized, placebo-controlled dietary intervention in overweight and obese participants (BMI>25.0 kg/m2) who are more likely to exhibit >1 of the 5 risk conditions associated with metabolic syndrome (MetS). BMI was the minimal criterion for recruitment.

Exclusion criteria

Participants were >18 years of age, not pregnant, not diabetic, with no unresolved infections or diseases (diabetes, CVD, IBD, cancer and liver disease), and nonsmokers. Histories of medication and dietary supplement use were collected and those taking anti-inflammatory or lipid-lowering medications were excluded.

Description:
Participants randomized to consume either placebo beverage or tart cherry juice at beginning of the study followed by a 2 week washout then switch over to the alternate beverage. Approximately half of participants began study consuming placebo beverage and the other half TCJ.
