“…The findings have been mixed. Some studies have reported no association between green or black tea and HDL‐C concentrations,26, 27, 28 whereas others have reported a significant positive association between tea consumption and HDL‐C concentration 24, 25. Of note, those observational studies were cross‐sectional study design, making it impossible to infer the temporal association between tea consumption and lipid profiles.…”

BackgroundThe relation between tea consumption and age‐related changes in high‐density lipoprotein cholesterol (HDL‐C) concentrations remains unclear, and longitudinal human data are limited. The aim of current study was to examine the relation between tea intake and longitudinal change in HDL‐C concentrations.Methods and ResultsBaseline (2006) tea consumption was assessed via a questionnaire, and plasma HDL‐C concentrations were measured in 2006, 2008, 2010, and 2012 among 80 182 individuals (49±12 years of age) who did not have cardiovascular diseases or cancer, or did not use cholesterol‐lowering agents both at baseline (2006) and during the follow‐up period (2006–2012). The associations between baseline tea consumption and rate of change in HDL‐C concentrations were examined using generalized estimating equation models. Tea consumption was inversely associated with a decreased rate of HDL‐C concentrations (P‐trend <0.0001) in the fully adjusted model. The adjusted mean difference in the HDL‐C decreased rate was 0.010 (95% confidence interval, 0.008, 0.012) mmol/L per year for tea consumers versus nonconsumers (never or less than once/month group). Interactions between tea consumption and age, sex, lifestyle scores, and metabolic syndrome (all P‐interaction <0.0001) were identified. The associations between greater tea consumption and slower decrease in HDL‐C concentrations were more pronounced in men, individuals aged 60 or older, individuals with a lower lifestyle score, and individuals with metabolic syndrome (all P‐trend <0.0001).ConclusionsTea consumption was associated with slower age‐related decreases in HDL‐C concentrations during 6 years of follow‐up.Clinical Trial Registration URL: http://www.chictr.org.

“…Most interest in the effects of green tea has been stimulated by emerging evidence linking green tea consumption with positive health outcomes. Epidemiological evidence has suggested that green tea consumption may be associated with a reduction in blood cholesterol levels 1,2 , cardiovascular disease and cancer 3 -5 . It has long been said that green tea induces a pleasurable mental feeling and recently green tea has received much scientific attention because of its positive psychological effects, thought to be caused by the novel amino acid theanine (g-glutamylethylamide) 6 -8 .…”

“…Although some studies have found no lipidlowering effects from green or black tea consumption, most showed hypolipidemic effects for tea [213][214][215][216][217][218]. The association between tea drinking and lipid profile concentrations was linear for up to 10 cups per day, beyond which the association disappeared [219]. Daily consumption of 10 cups of green tea was associated with a reduction of approximately 2% in serum total cholesterol [219].…”
