Conditions
Brief summary
The primary objective of this study is to investigate if chlorogenic acid will increase circulating nitric oxide and if these effects are associated vascular benefits.
Interventions
A randomised, controlled cross-over design trial will be conducted to investigate the acute effects of chlorogenic acid on metabolism of nitrogen oxides,as well as blood pressure and endothelial function. Each participant will complete 2 visits (one treatment at each visit) one week apart in random order. The two treatments are: 1. No chlorogenic acid 2. Chlorogenic acid Prior to each visit participants will be asked to consume a standard low flavonoid meal for breakfast. Participants will then attend the School of Medicine and Pharmacology Research Unit at Royal Perth Hospital where they will be provided with 400 mg chlorogenic acid in 200 ml water.
