Green Tea from the Far East to the Drug Store: Focus on the Beneficial Cardiovascular Effects

Abstract

: Cardiovascular diseases(CVD) are the leading cause of death worldwide. Evidence from observational and randomized controlled studies showing the potential benefits of green tea on lowering CVD risk has been emerging rapidly during the past few decades.These benefits include reduced risk for major cardiovascular events, lowering of blood pressure, decreased LDL cholesterollevels and weight loss.At the same time, the understanding of physiological mechamismsbehind these alterations is advancing.Consumption of green tea originates from China thousands of years ago, but has since expanded all over the world.Recent advances in understanding the role of tea polyphenols, mainly catechins,as mediators of tea’s health benefits has caused an emergence of various types of green teaextracts(GTE) on the market. While drinking green tea is generally considered safe, there are concerns about thesafety of using tea extracts. The present article reviews the current evidence of green tea consumption leading to reducedCVD risk, the phenomenon’s potential biological mechanisms and the safety of using GTE.

“…The catechins and vitamins are associated with the health benefits of green tea including its anti-inflammatory, anticarcinogenic and antimicrobial properties (Reygaert 2017). Green tea has also been reported to reduce the risk of cardiovascular disease (Landini, Rebelos & Honka 2021;Sumpio et al 2006) and enhance oral health (Gaur & Agnihotri 2014;Liao et al 2021).…”

“…Green tea ( Camellia sinensis ) is the most consumed beverage in the world (Ke et al, 2019). Evidence concerning the health benefits of tea is mounting, with the interest that tea plays an important regulatory role in metabolism and cardiovascular health (Bond & Derbyshire, 2019; Landini et al, 2021). Clinical studies also found that the consumption of green tea in Japanese patients is negatively correlated with AMI.…”
