China and India both have a long history of cultivating tea, but tea originated in China, and was discovered by Chinese Emperor Shennong. Today, India is one of the largest producers of tea in the world, and we consume almost seventy percent of the tea produced in our country. As fascinating as the story of its origin, tea is not only refreshing it also has loads of benefits.
The different types of tea are white, yellow, black, green and oolong, but out of these, the black and green tea, are most commonly used because of their health benefits. In what aspects green tea and black tea are different from one another? Both of them come from the same leaves of Camellia sinensis plant. The categorization starts at the fermentation level (also called as oxidation level). In this process the green tea is prevented from oxidation by steaming and baking the leaves, and hence the leaves retain their colour. But in the case of black tea, the leaves are oxidized and the colour of leaves change from green to black. Green tea contains an antioxident called epigallocatechin gallate (EGCG), whereas this antioxidant converts into theaflavins and thearubigens, according to WebMD Medical News.
Health benefits of both black and green tea:
Tea is known as an antioxidant drink, the antioxident potential in tea is more when compared with grape juice or red wine. Antioxidants prevents the cells in body from the ill effects of free radicals. Tea contains vitamin B6, which helps in the process of metabolism. It also contains vitamin B1 and vitamin B2 which are required to release energy from the food.
Tea is also a rich source of minerals such as magnesium, potassium and fluoride. Magnesium is required for the development of bones and body growth, potassium is used to maintain the fluid levels in the body, and also for the pumping of the heart, and fluoride prevents tooth decay, and strengthens the enamel on the teeth.
Tea is an inexpensive way to prevent diabetes. Researchers says that tea helps in decreasing the glucose level in the blood and improves insulin activity. A study done by American Heart Association in New Orleans found that, the individuals who drink black tea are at a lower risk of heart attack and heart stroke. It expands the arteries which supplies blood to the heart and helps in increasing the blood flow. The flavinoids present in the tea are good for the heart.
