Adult consumers of cranberry juice cocktail have lower C-reactive protein levels compared with nonconsumers.
Flavonoids are important bioactive plant constituents found in abundance in berries, including cranberries. Cranberry beverages have been shown to beneficially impact urinary and cardiovascular health in clinical and observational studies, but their association with anthropometric outcomes is unknown. We examined the association between cranberry juice cocktail (CJC) consumption with flavonoid intake, and cardiometabolic and anthropometric outcomes among adults in the US data for adults (>19 years, n = 10334) were drawn from cross-sectional National Health and Nutrition Examination Survey combined 2005-2008 survey. We hypothesized that CJC consumers will have lower anthropometric measures and healthier cardiometabolic profiles, including lower cholesterol and C-reactive protein (CRP). A CJC consumer (n = 330) was defined as anyone consuming CJC for 2 nonconsecutive 24-hour dietary recalls. We used multivariate linear regression models to examine differences in anthropometric and cardiometabolic outcomes comparing CJC consumers to nonconsumers controlling for important confounders. Consumers drank an average 404 mL (14 fl oz) of CJC for 2 days and did not have higher total energy intakes compared with nonconsumers (mean [SD], 2259  vs 2112 , respectively). In fully adjusted models, adult CJC consumers had significantly lower levels of CRP (mean [SD], -0.13 [0.05]; P = .015), results that were strengthened after further adjustment for body mass index (mean [SD], -0.98 [0.04]; P = .027). Trends toward lower weights and lower levels of cholesterol did not reach statistical significance. Intake of cranberry polyphenols may play a role in promoting anti-inflammatory markers among CJC consumers, specifically lowering CRP levels
