Implication
Tea may acutely benefit endothelial function in healthy adults; extends small-trial data but leaves open outcome relevance.
Structured PICO
Does green tea consumption improve endothelial function in healthy individuals?
P
Population
14 healthy individuals, mean age 30+/-3 years, with no cardiovascular risk factors except smoking (50%)
I
Intervention
6 g of green tea
C
Comparator
125 mg of caffeine (the amount contained in 6 g of tea) or hot water, administered on separate occasions
O
Outcome
Flow-mediated dilatation (FMD) of the brachial artery measured before each intervention and 30, 90, and 120 min afterwardsurrogate
Green tea consumption acutely improves endothelial function in healthy individuals, which may contribute to its cardiovascular benefits.
