Green tea is the drink of longevity.
It is rich in antioxidants and nutrients, improves brain function, helps you lose weight, reduce the risks of cancer and has powerful healing effects.
In this article I will show you 10 benefits of green tea, taken from the site Authority Nutrition, which were demonstrated with studies and research.
1. Green tea contains bioactive compounds that improve the health
Many of the bioactive compounds found in tea leaves end up in the drink, which contains a wealth of important nutrients.
It is rich in flavonoids and polyphenols as catechins, which are powerful antioxidants (read here the study).
These substances can reduce the formation of free radicals in the body, protecting cells and molecules. Antioxidants play a fundamental role in counteracting the aging and prevent all manner of diseases.
One of the most potent compounds in green tea is the antioxidant Epigallocatechin gallate (EGCG) which, as shown by several studies, is one of the main reasons why green tea has many medicinal properties.
Green tea also contains trace minerals that are very important to your health.
But be warned: only buy good quality green tea and organic farming, because some low quality tea may contain very high levels of fluorine (read here the study).
2. Green tea compounds improve brain health
Green tea not only makes you more alert and active, but also smarter.
The compound that makes it so “Activator” is caffeine.
Green tea does not contain so much as the coffee, but enough to produce a response without causing the peak effect of energy and caffeine jitters.
What caffeine does to the body is blocking inhibitory neurotransmitter called adenosine. This increases the production of neurons and the concentration of neurotransmitters such as dopamine and norepinephrine (read here the studies 1, 2).
Caffeine has long been studied for effects on several aspects of brain function, such as improving mood, the effect of “activating”, reaction time and memory (read here the study).
The beauty is that green tea contains caffeine. It also contains the amino acid L-theanine, which is capable of crossing the blood-brain barrier (read here the study).
The L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has the effect of calming and to counter anxiety. It also increases dopamine and produce alpha waves in the brain (1, 2, 3 studies here).
Studies have shown that caffeine and L-theanine may have synergistic effects. The combination of these two compounds can improve brain function (read here the study).
Thanks to the content of L-theanine and small amounts of caffeine in green tea can give you a sense of increased energy more bland and more balanced than the coffee.
Many people have claimed to feel more energetic when they drink green tea than when drinking coffee.
3. Green tea has a fat-burning effect and improves physical performance
Very often in the ingredient list of supplements to burn fat and lose weight there is green tea green tea 3.
In fact, green tea has proven to burn fat and boost metabolism in controlled studies made about man (read here the studies 1, 2).
In a study done on 10 men in health, green tea has been able to increase by 4% the energy yield from FAT (read here the study).
It is important, however, point out that some studies on green tea showed no obvious effects on the metabolism, so there may be differences from one case to another (read here the study).
Caffeine has been shown to improve physical performance, shifting the fatty acids from fatty tissues and making them available to derive energy (read here the studies 1, 2).
In two separate studies, caffeine has shown an increase of 11-12% on average physical performance (read here the studies 1, 2).
4. the antioxidants garcinia cambogia customer reviews 2016 contained in green tea can reduce the risk of various cancers
Cancer is caused by an uncontrolled cell growth.
It is common knowledge that oxidative damage contributes to the development of cancer and that antioxidants may have a protective effect (read here the study).
Green tea is an excellent resource of powerful antioxidants, this reduces the risk of cancer:
• Breast cancer: A meta-analysis of observational studies showed that women who drink more green tea have a 22% reduction of the risk of breast cancer, the most common in women (read here the study).
