PURPOSE We sought to evaluate the link between long-term tea intake and prevalence of type 2 diabetes mellitus, in a sample of elderly adults. MATERIALS AND METHODS During 2005-2007, 300 men and women from Cyprus, 142 from Mitilini, 100 from Samothraki, 114 from Kefalonia, 131 from Crete, 150 from Corfu and 103 from Zakynthos (aged 65 to 100 years) were enrolled. Dietary habits (including tea...

BACKGROUND Coffee consumption has been reported to be inversely associated with risk of type 2 diabetes mellitus. Similar associations have also been reported for decaffeinated coffee and tea. We report herein the findings of meta-analyses for the association between coffee, decaffeinated coffee, and tea consumption with risk of diabetes. METHODS Relevant studies were identified through searc...

(1) Background: Endothelial dysfunction predicts cardiovascular events. Circulating angiogenic cells (CACs) maintain and repair the endothelium regulating its function. Tea flavonoids reduce cardiovascular risk. We investigated the effects of black tea on the number of CACs and on flow-mediated dilation (FMD) before and after an oral fat in hypertensives; (2) Methods: In a randomized, double-bl...

Green tea and coffee consumption may decrease the risk of some types of cancers. However, their effects on biliary tract cancer (BTC) have been poorly understood. In this population-based prospective cohort study in Japan, we investigated the association of green tea (total green tea, Sencha, and Bancha/Genmaicha) and coffee consumption with the risk for BTC and its subtypes, gallbladder cancer...

OBJECTIVES Green tea has been suggested to have a chemopreventive effect against various cancers including stomach cancer. The aim of this study is to elucidate the relationship between green tea consumption and stomach cancer risk by meta-analysis. METHODS Eighteen observational studies were identified using MEDLINE, THE COCHRANE LIBRARY, RISS, and a manual search. Summary relative risks/odd...

OBJECTIVE The aim of this study was to assess the relationship of tea consumption with common carotid artery intima-media thickness (CCA-IMT) and carotid plaques. METHODS AND RESULTS The study was performed on 6597 subjects aged > or = 65 years, recruited in the French population for the Three-City Study. Atherosclerotic plaques in the extracranial carotid arteries and CCA-IMT were measured u...

BACKGROUND Fractures are important causes of healthy damage and economic loss nowadays. The conclusions of observational studies on tea consumption and fracture risk are still inconsistent. The objective of this meta-analysis is to determine the effect of tea drinking on the risk of fractures. METHODS A comprehensive literature search was conducted in PubMed, Embase and reference lists of the...

Epidemiological observations suggesting an inverse correlation between tea consumption and the incidence of cardiovascular diseases have been well established [1–4]. The review by Stangl et al. gives an overview of the effects of polyphenolic compounds in tea on the function of the cardiovascular system, especially on various signal transduction pathways in cardiovascular cells [5]. The underly...

Intestinal absorption of non-heme food iron may be inhibited by tea, which, on the contrary, does not exert any appreciable effect on heme iron assimilation. Therefore, while an iron-deficiency anemia cannot develop in non-vegetarian subjects as a consequence of tea consumption only, it is possible that tea could inhibit the therapeutic effect of oral iron drugs, which are usually non-hemic fer...

Study objective—To relate habitual (cups per day) tea and coVee consumption to conventional coronary risk factors and subsequent risk of coronary heart disease and death. Design—Cohort study. Setting—Nationwide random population study. Participants—Over 11 000 men and women aged 40–59 who took part in the Scottish Heart Health Study lifestyle and risk factor survey in 1984–87. Participants were...
