Both green tea and wu yi tea are very good for the body. They each contain vitamins and nutrients that help to protect the body from harmful free radicals and help improve your cholesterol. Both tea products come from the same source but the difference is where and how they harvested.
Nevertheless, these natural substances come in different concentrations in green tea and wu yi tea. The main reason for this is the different fermentation processes that these tealeaves undergo. Green tea is dried and packaged without fermentation. Wu yi tea, on the other hand, is semi-fermented. This means that wu yi undergoes a certain level of fermentation under the sun that of course affects its flavor, aroma and texture, and the concentration of substances in it as well.
There are very important substances in tea that are fantastic for good health such as: cathecin, polyphenols, flavin, and tearubigin, these are subcategorized and are in the tannin classification. The difference in the two types of teas is the amounts of these nutrients.
Caffeine, also called theine when found in tea, concentration in both green and wu yi tea are the same. In some recent studies, caffeine has turned from being a harmful substance to a beneficial one. Researchers are still ongoing but preliminary data show that caffeine may reduce the risk of suffering from Parkinson’s disease, type-2 diabetes, and colon cancer.
Wu yi tea differs slightly in the tannin sub group classification. Wu yi tea has less amounts of cathecin than green tea. Cathechin plays a role in reducing the risk of diabetes, heart failure, and stroke. It is also very important in delaying the aging process.
However, wu yi tea contains higher levels of teaflavin and tearubugin. These make up the natural ability to lower blood cholesterol and prevent dementia from old age.
The biggest difference is in there levels of polyphenols. There is a much higher concentration in wu yi tea compared to green tea. Polyphenols help to reduce the risk of cancer, diabetes, cardiovascular disease, osteoporosis, and many other diseases. It is a very powerful antioxidant compound that works to remove toxins from our body.
