There are many potential health benefits ascribed to green tea, which has been savored around the world for generations as a stress reducer and overall agent of wellness. The University of Maryland Medical Center cites past research connecting green tea to improved outcomes against heart disease, diabetes and various cancers. Recently, researchers from the Oxford University in the United Kingdom and the University of Washington collaborated on a review of green tea studies – specifically those relating to the beverage, high blood pressure and cholesterol.
High blood pressure, or hypertension, is a serious condition that affects roughly a third of U.S. adults. It is a risk factor for heart disease and stroke, both of which can substantially impair brain health. According to a study abstract published by the medical journal Nutrition, Metabolism and Cardiovascular Diseases, the scientists analyzed 20 clinical trials to determine the effects of green tea consumption on this issue. High cholesterol is another substantial problem that is directly linked to heart health and hypertension, so the researchers also focused on this concern.
Overall, the researchers noted subtle improvements in blood pressure and cholesterol among people who routinely drank green. tea. "Green tea intake results in significant reductions in systolic blood pressure, total cholesterol, and LDL cholesterol. The effect [...] on systolic blood pressure is small, but the effects on total and LDL cholesterol appear moderate," the source states.
The scientists noted that more research is necessary to investigate this relationship. However, green tea is known to be an excellent source of antioxidants, which help protect the body's cells from free radicals.
