ULTRASOUND ASSESSMENT OF BRACHIAL ARTERY FLOW-MEDIATED DILATION FOLLOWING ACUTE KOMBUCHA TEA CONSUMPTION IN HEALTHY MEN

INTRODUCTION: Endothelial dysfunction has been accepted as the first step in the atherogenic process. Chronic tea consumption is inversely related to cardiovascular disease, and short-term ingestion can transiently improve endothelial function using percent change in flow mediated dilation (FMD%) as an index. Kombucha tea has many claimed health benefits, including the ability to improve endothelial function; although this has not been scientifically investigated. AIM: The primary aim was to compare acute ingestion of black and Kombucha tea on FMD% at three time points following consumption. METHODS: Four healthy men received black or Kombucha tea in a randomized, double blinded cross-over design. FMD% was analyzed at baseline, immediately, 2, and 4 hours following consumption of the test drinks. RESULTS: For FMD%, no significant main effects for treatment or treatment*time were seen (P > 0.05). Significant main effect for time (P = 0.012) with post hoc analysis indicating no significant difference between time periods (P > 0.05). CONCLUSION: Individuals responded to black and Kombucha tea differently, but grouped means influenced FMD% similarly demonstrating potential benefits for vascular health based on consumption of both tea varieties. However, the small homogenous sample limits the interpretation and application of these findings.
