Mechanisms of Body Weight Reduction and Metabolic Syndrome Alleviation by Tea
Tea, a popular beverage made from leaves of the plant Camellia sinensis, has been shown to reduce body weight, alleviate metabolic syndrome, and prevent diabetes and cardiovascular diseases in animal models and humans. Such beneficial effects have generally been observed in most human studies when the level of tea consumption was 3 to 4 cups (600–900 mg tea catechins) or more per day. Green tea is more effective ...

Mate and Tea Intake, Dietary Antioxidants and Risk of Breast Cancer: a Case-Control Study
Recently, we reported an inverse association between high ‘mate’ intake (infusion of Ilex paraguariensis herb, a staple beverage in temperate South America) and breast cancer (BC) risk. Stronger inverse associations were found in high strata of tea, vegetable, fruit and energy intakes, and in overweight/obese women, suggesting possible roles for ‘mate’ mainly from its antioxidant contribution. ...

Long-Term Supplementation of Green Tea Extract Does Not Modify Adiposity or Bone Mineral Density in a Randomized Trial of Overweight and Obese Postmenopausal Women
Abstract
Background: Green tea extract (GTE) consumption has been linked to favorable changes in adiposity and bone mineral
density (BMD), although it is unknown if these effects are due to green tea catechins or caffeine. The catechol-Omethyltransferase
(COMT) genotype may also modify these associations.
Objective: We ...

Long-Term Green Tea Extract Supplementation Does Not Affect Fat Absorption, Resting Energy Expenditure, and Body Composition in Adults
Background: Green tea (GT) extract may play a role in body weight regulation. Suggested mechanisms are decreased fat
absorption and increased energy expenditure.
Objective:We examined whether GT supplementation for 12 wk has beneficial effects on weight control via a reduction in
dietary lipid absorption as well as an increase in resting energy expenditure ...
