Green tea consumption has been shown to benefit many health issues ranging from help with weight management to cancer prevention and treatment. New research published in the British Journal of Nutrition explains that the natural extract from the Camellia sinensis plant has a powerful effect on cholesterol metabolism in the human body.
Most forward thinking health professionals now understand that dysfunction in the LDL cholesterol pathway lays the foundation for cardiovascular health problems, cancer and fatty liver disease. Regular green tea consumption is now shown to improve healthy LDL cholesterol function, enabling the fatty molecule to efficiently usher excess cholesterol from the body and improve risk factors for many chronic disease conditions.
Green Tea Alters Gene Expression Lower LDL Cholesterol Levels
In one of the first studies of its type, researchers performed DNA microarray analysis to examine the effect of the active compound found in green tea called epigallocatechin gallate (EGCG). Scientists specifically targeted the catechin to determine their effect on cholesterol metabolism in HepG2 hepatocytes. They determined that the expression levels of several genes related to cholesterol metabolism, including the LDL receptor, were changed by EGCG treatment.
EGCG was found to boost the function of the LDL receptor on liver cells. Researchers commented “This is very important as proper function of the LDL receptor enables your liver to “capture” circulating LDL and recycle it.” In this study, green tea is shown to alter gene expression toward healthy LDL cholesterol metabolism by improving receptor acceptance by the liver. The liver displays an improved capacity to capture and filter LDL cholesterol for removal from the body.
Green Tea Improves Biomarkers to Lower Heart Disease, Cancer and Dementia Risks
In addition to the finding that green tea alters LDL cholesterol metabolism, ECGC was found to inhibit genes to reduce the production of Apolipoprotein B (ApoB). ApoB formation is required to initially form LDL molecules in the blood. Excess production of ApoB is a significant marker for chronic illnesses ranging from cardiovascular disease and heart attack to increased risk of cancer and dementia.
Green tea and the active compound EGCG are quickly ascending to nutritional “superstar” status. The Chinese have extolled its virtues for countless generations. Researchers now document the prowess of this nutrient by scientifically validating the direct impact exerted on our genetic structure to affect healthy cholesterol function and removal from the body. The healthy benefits of green tea are realized by drinking several fresh brewed cups of organically harvested leaves each day or supplementing with 250 to 500 mg of EGCG extract.
