TEA & HEALTH

In today's marketplace it's almost impossible not to notice how popular tea has become. And although it's been around for centuries, tea has been getting a lot of press lately for it's healing and therapeutic properties.

At macha we are very interested in tea as part of a healthy lifestyle, but we also want to be careful about making the same general claims often used to market tea products.

What we do know is that there are naturally occurring compounds in tea (especially green and herbal teas) that help promote good health. Green teas contain high levels of unoxidized polyphenols, which are plant compounds that have antioxidant properties. Antioxidants help to control free radicals—unstable molecules which contribute to the development of chronic disease.

One of the most powerful polyphenols is epigallocatechin gallate, or EGCG. Found only in green tea, EGCG is being studied for it's promising role in cancer prevention.

Other studies have linked tea (mostly green and herbal) to the following:

  • oral health through plaque prevention
  • cardiovascular health
  • reduced cholesterol
  • weight loss
  • strong immunity
  • healthy digestion

There is a lot of research out there, and it can be overwhelming, so here are just a few links:

Key terminology

Antioxidants

Catechins
The most important component in the polyphenol family; a type of flavonoid found primarily in tea.

Drying/Firing
Halts oxidation of tea

EGCG
Epigallocatechin gallate is a catechin found in the highest concentration in green tea. Currently being researched for it's promise in cancer prevention.

Fermentation/Oxidation
A chemical reaction that occurs between the air and the tea leaf's natural juices as a result of bruising or crushing. The amount of oxidation depends upon how much of the enzymes are exposed and for how long.

Flavonoids
A large subclass of polyphenols that is responsible for the tea's color as well as health benefits.

L-theanine
Unique amino acid found in green tea which promotes relaxation and concentration without drowsiness, and reduces the side effects of caffeine. Theanine is found almost exclusively in tea.

Polyphenols
Plant compounds with antioxidant activity responsible for the variety of characteristics that give tea its unique flavors. Emerging science suggests they may play an important role in long-term health.
