Tea and Coffee Consumption and Cardiovascular Morbidity and Mortality

Abstract

High tea consumption is associated with a reduced risk of CHD mortality. Our results suggest a slight risk reduction for CHD mortality with moderate coffee consumption and strengthen the evidence on the lower risk of CHD with coffee and tea consumption.

Coffee consumption and risk of stroke: a meta-analysis of cohort studies

“…The 13 studies that contribute to this meta-analysis were from 6 different countries: USA [9][10][11][12], Finland [13,14], Sweden [15,16], Netherland [17,18], Italy [19] and Japan [20,21]. Three studies included only women, three included only men, and the others included both genders: The follow-up years ranged from 2 to 25; The number of participants ranged from 499 to 120852; The number of new stroke cases ranged from 54 to 3090; Four of the studies presented the RR of ischemic stroke and hemorrhagic stroke separately, and the rest only reported the overall RR of all types of stroke; The endpoints of the studies were different.…”

Consumption of a boiled Greek type of coffee is associated with improved endothelial function: The Ikaria Study

“…11,40 There is convincing evidence that coffee consumption acutely impairs endothelial function. 6 Nevertheless the impact of chronic coffee intake on endothelial function is largely unknown. Data from epidemiological studies have not confirmed a detrimental effect of chronic coffee consumption 41 on endothelial function, while coffee beverages without caffeine have shown a beneficial effect.…”

“…[1][2][3][4][5] Recent studies suggest a slight risk reduction for coronary heart disease mortality with moderate coffee consumption. 6,7 Moreover, favorable effects of chronic caffeine administration on endothelial cell migration, on re-endothelialization and on the expression of nitric oxide synthase enzyme have also been reported. 8,9 It is known that endothelium plays a key role in vascular function and parameters of vascular function and structure show important clinical impact and are associated with cardiovascular risk.…”

Tea and human health: biomedical functions of tea active components and current issues

“…Research in USA and Europe demonstrated that black tea drinking could decrease the risk of CVD (Deka and Vita, 2011). Another study (de Koning Gans et al, 2010) in the Netherlands involving 37 514 healthy males and females who were followed up for 13 years indicated that the mortality from CVD was decreased by a daily consumption of 3-6 cups of black tea. It is suggested that the reduction in mortality can be attributed to the maintenance of cardiovascular health through green tea consumption (Nakachi et al, 2000;Sano et al, 2004;Yusuf et al, 2005).…”
