Clinical Trial Summary

Epidemiological studies have indicated that the consumption of citrus fruit is inversely associated with the risk of cardiovascular disease. However, clinical data regarding the effects of blood orange juice upon endothelial function is scarce. This randomised, crossover study investigates whether blood orange juice compared to a control drink improves blood vessel function and other cardiovascular health indicators (such as blood pressure and blood lipids). All the subjects will be asked to consume blood orange juice and a control drink in a randomised order, each over a 2-week period, divided by a 1-week wash out period.


Clinical Trial Description

Endothelial function measured via flow mediated dilation (FMD), blood pressure, anthropometric measures, lipid profile, high-sensitivity C-reactive protein (hsCRP) and endothelin 1 (ET-1), cyclic guanosine monophosphate (cGMP) will be evaluated in healthy overweight/obese Caucasians prior to and following 2-week consumption of blood orange juice and a control drink. Evaluation of endothelial function as measured by FMD will be conducted on specific days of the menstrual cycle to minimise the fluctuation in oestrogen levels in premenopausal women, which will be monitored in serum samples. ;
