Antioxidant Vitamins.

 


Japanese green tea leaves are rich in antioxidant vitamins, such as vitamin C, vitamin E and βcarotene. In addition to antioxidative activity, these vitamins have anti-tumor effects and suppress aging. Commercial Japanese green tea leaves contain vitamin C approximately 280 mg per 100 g dried weight. By administration of vitamin C to rats, lipid peroxidation of liver was decreased. Vitamin C has also antimutagenic effect. Japanese green tea leaves contain about 70 mg of vitamin E per 100 g dried weight. Vitamin E suppresses the peroxide lipid synthesis.β- carotene has a radical scavenging function which prevents skin cancer. Vitamin E and β-carotene are water insoluble matter. In order to ingest vitamin E and β- carotene, eating whole tea leaves as Matcha is necessary.

 Japanese green tea contains γ-glutamylethylamide , named theanine, at the level from 1 to 2 % in dried leafy materials. While most amino acids are found at lower level, theanine accounts for＞50 % of total free amino acids in tea. Theanine is the source of Japanese green tea’s characteristic delicious taste  (known as“umami”). There is a scientific interest about the biological effect of theanine on central nervous system. ■ Relaxation Effect: The relaxation feeling after drinking Japanese green tea may be linked with the presence of theanine. Studies on animals and human volunteers showed that oral administration of theanine generated α- waves in the brain, suggesting that theanine could bring about a relaxation feeling, because brain α- waves are generated under relaxing condition.   ■  Effect on Blood Pressure:  When theanine was orally administered to spontaneously hypertensive rats (SHR), their blood pressure was decreased in a dose dependent manner.

What's driving young people to embrace tea?

Amy and Hannah Little, the Millennial co-founders of Tour de Tea in Brisbane, Australia, are actively trying to promote tea culture to their peers and the next generation of tea drinkers.  Welcome to explore what the younger generation is drinking though a global lens , to learn how they're learning about the tea industry , the role social media plays, and more!  To start things off, we begin with a look at what's driving young people to embrace tea . As someone who grew up watching the TV show, Friends, I recall Central Perk, the coffee shop featured in the show, as epitomizing the gravitational pull of coffee among social circles when much of Gen X was still in college and the older of the generation had started their first jobs. Mug in hand, the six friends would complain about their love lives, their bosses, and quip about living in Manhattan, often exchanging giant coffee mugs as their friend and waitress, Rachel played by Jennifer Aniston, would get their orders wrong.
