Purified black tea theaflavins and theaflavins/catechin supplements did not affect serum lipids in healthy individuals with mildly to moderately elevated cholesterol concentrations.

Background: Ingestion of tea flavonoids found in both green and black tea is linked to cardiovascular health benefits such as lowering serum lipids. Evidence for a cholesterol-lowering benefit of green or black tea consumption from human intervention studies is, however, conflicting and active components responsible for the effect have not yet been clearly identified.

Aim Of The Study: In a randomized, double-blind, placebo-controlled, parallel design study the effects of ingesting a purified black tea theaflavins (TFs) powder alone or in combination with catechin (TFs/catechins) on lowering serum total (TC) and LDL-cholesterol (LDL-c) were assessed.

Black tea consumption dose-dependently improves flow-mediated dilation in healthy males.

Objectives: Flavonoids may protect against cardiovascular disease. Tea is a major source of dietary flavonoids. Studies indicate black tea improves endothelial function but data on arterial haemodynamics, blood pressure (BP) and insulin resistance are equivocal.

Plant sterol-enriched milk tea decreases blood cholesterol concentrations in Chinese adults: a randomised controlled trial.

The cholesterol-lowering effects of plant sterols in a format suitable for use in China have not previously been investigated. We conducted the study to quantify in adult Chinese the effects on blood lipid concentrations of a plant sterol-enriched milk tea powder. The study was a double-blind, randomised trial in which 309 participants were randomised to receive daily 2.

Cholesterol ester transfer protein (CETP) Taq1B polymorphism influences the effect of a standardized cardiac rehabilitation program on lipid risk markers.

Cardiac rehabilitation programs (CR) are standard treatment for patients with coronary artery disease (CAD), yet a large variation in risk factor and lipoprotein changes exists. We investigated the role of three common genetic polymorphisms (CETP Taq1B, LIPC -514 and apo E) associated with alterations of lipoprotein metabolism, in patients before and after standardized CR. Three-hundred and seven patients were recruited for this study.
