It was long ago that coffee was initially encouraged to drink in the coffee houses of Mecca as caffeine was then seen as a health benefit. With this in mind, it’s rapid popularity swept across the globe and became apart of the Arab culture as well. It was not until 1615 that Venetian traders brought it to Europe, where it became the fastest growing market in the world. However, one cannot help but question whether such a good tasting, beneficial beverage has a hidden catch.
With such high interest in this new phenomenon, it has been found that green tea “contains an amino acid called theanine, which can cross the blood-brain barrier reducing stress and possibly promoting better cognitive function,” states Marshall. Along with this rather exciting information, green tea can also help reduce the risk of cancer and heart disease. John Foxe, a professor of neuroscience studies the effects of tea on the brain and found that "within 20 minutes of drinking a cup of tea, there was an impact on the brain's alpha waves," which are lowered due to the theanine content within tea increasing levels of concentration.
On top of all the mental benefits green tea has on the human mind, there are also several findings of physical benefits. To name one, the fluoride levels in green teas “are generally comparable to those recommended for the prevention of dental caries (cavities)” states Jane Higdon, a PHD at Oregon State University. She also found that green tea could help reduce reception of kidney stones. The favorite physical finding to many is the result of higher metabolism, which can lead to weight loss with the correct diet. On top of this, drinking this tasty tea also takes care of water consumption without the added calories or sugar. There are still several research studies being conducted, leading to even more reasons to drink green tea. However, even though green tea contains much lower levels of caffeine compared to green tea, as shown on the chart to the right, highly active people should still be cautious of their caffeine consumption. So how much should be consumed to get just the right effect of all the benefits? Marshall found that “people should drink between three and six cups per day” in order to get the maximized “bang”.
Next time the urge for caffeine and energy consumes the body, grab a cup of green tea to rejuvenate and energize both the body and mind. The performance world is upbeat, competitive, and demanding, and it is essential to be on top of the game at all times. Since coffee can actually lead to a trip to the hospital, ruining the career and body, why not switch? After all, the exchange of coffee for tea may actually save a life or two.
