Green tea consumption linked to improvements in total and LDL cholesterol



Numerous studies have confirmed the health-supportive benefits of green tea consumption, as the ancient Chinese drink helps to prevent many forms of cancer and lowers the risk from cognitive decline and dementia. The result of a systematic literature search published in the Journal of the American Dietetic Association finds that green tea supplied from drink or supplements lowers total cholesterol and artery-clogging LDL cholesterol. Green tea contains antioxidant compounds called catechins (specifically EGCG) that pack a powerful anti-inflammatory punch to our metabolism. These biologically active compounds from green and white tea have a direct and dramatic effect on blood lipids that help lower total cholesterol and more importantly that reduce atherogenic small, dense LDL cholesterol particles, which lower cardiovascular disease risk.

Study leader, Dr Olivia J. Phung of the College of Pharmacy at Western University of Health Sciences in Pomona, California decided to collect and analyze all available evidence from a multitude of prior studies on green tea and lipid modification. Dr. Phung and her team examined the relationship between consumption of green tea catechins and changes in levels of total, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol and triglycerides to establish a pattern of benefits for cardiovascular health.
