Green tea is more than just a liquid.
Did you know green tea could help you feel better, lose weight and lower your risk of chronic diseases? No! Well you might want to consider making this healthy beverage a regular part of your daily routine.
It is loaded with antioxidants and nutrients that have powerful effects on the body. These include improved fat loss, brain function, a lower risk of cancer and many other impressive benefits.
1. Green Tea Increases Fat Burning and Improves Physical Performance
If you look at the ingredients list for any fat burning supplement, chances are that green tea will be on there.
In one study in 10 healthy men, green tea increased energy expenditure by 4% (14).
Another study showed that fat oxidation was increased by 17%, indicating that green tea may selectively increase the burning of fat (15).
However, some studies on green tea don't show any increase in metabolism, so the effects may depend on the individual (16).
2. Brain Function and Mental Performance Improvement
While the stimulants in tea can keep you awake, they can also make your brain function better. The main stimulant, caffeine, is present in tea at enough of a dose to provide a lift for most people without causing the increased anxiety and “jitters” associated with too much coffee.
In the brain, the main method of action of caffeine is to block adenosine receptors, allowing neurons to fire for longer, increasing brain activity. Studies have shown caffeine improves concentration and memory.
Additionally, the amino aide L-theanine has a relaxing effect while simultaneously increasing alertness, which, in combination with caffeine, can increase brain function and help you be more productive.
3. Green Tea Can Kill Bacteria, Which Improves Dental Health and Lowers Your Risk of Infection
The catechins in green tea also have other biological effects.
