Green tea has been consumed for centuries, with its origins likely dating back to prehistoric times. It was first cultivated in Asia and offers more health benefits than black tea, even though they come from the same plant. The difference is that black tea undergoes more extensive processing, which robs it of some of the health-promoting properties.
While the early users of green tea may not have understood the scientific reasons behind its benefits, they could observe the positive effects on their health. Modern science has since caught up, providing a better understanding of why green tea is so beneficial.
Tea contains flavonoids and polyphenols, including a specific compound called catechin, which acts as a powerful antioxidant. These compounds have a range of positive impacts on health, including:
Preventing heart disease: The compounds in green tea work to lower the absorption of cholesterol in the intestines, reducing the buildup of cholesterol in the blood vessels and lowering the risk of heart disease.
Improving liver function: Alternative medicine practitioners recommend green tea to help flush out built-up toxins from the liver, which acts as the body’s main filtration system.
Aiding weight loss: Green tea can reduce the absorption of fat and lower the secretion of leptin, a hormone that makes you feel hungry. It can also boost metabolism, helping you burn more calories even at rest.
Reducing cancer risk: Studies have shown a link between drinking green tea and a lower risk of certain types of cancer, as long as it is not consumed at excessively high temperatures, which could increase the risk of esophageal problems.
Regulating blood sugar levels: Researchers have found that green tea can help manage blood sugar levels, making it potentially beneficial for individuals with diabetes.
While our ancestors may not have fully understood the science behind green tea’s benefits, they were able to observe the positive impact it had on their health. Thanks to modern research, we now have a better grasp of the mechanisms by which green tea promotes overall well-being.
