A healthy habit in your daily life makes you healthy and wise.
A food with a lot of health benefits is known as a superfood and green tea is definitely one of them. Green tea has captivated the hearts of people around the world for centuries. Most of us have tea or coffee during the day, be it morning or evening, green tea is a healthy alternative to everyday tea or coffee. This beverage is derived from the leaves of Camellia sinensis. Green tea has been used for medicinal purposes in China and Japan for many years. It stands apart not only for its unique flavor but an array of health benefits. Its remarkable qualities include its antioxidant and anti-inflammatory properties, its significance in weight management, and aids in the prevention of cancer, cardiovascular and other chronic diseases.
WHY IS IT CALLED GREEN TEA AND HOW IT IS DIFFERENT FROM BLACK TEA?
Almost every tea is made from the leaves of camellia sinensis, but the process of making is different. For the production of black tea, the leaves are rolled and then exposed to air during which they go through oxidation acquiring the black colour whereas for green tea the leaves are steamed or pan-fried and then dried which retains their green colour while preventing too much oxidation from occurring.
Green tea is different from other tea as its liquid is directly acquired from the leaves and hence retains more antioxidants and polyphenols for the body to use.
