This is a detailed article about green tea and its health benefits. Green tea is high in antioxidants that can improve the function of your body and brain.
Green tea is more than just a hydrating beverage.
The green tea plant contains a range of healthy compounds that make it into the final drink.
Tea is rich in polyphenols, which are natural compounds that have health benefits, such as reducing inflammation and helping to fight cancer.
Green tea contains a catechin called EGCG (epigallocatechin-3-gallate). Catechins are natural antioxidants that help prevent cell damage and provide other benefits.
These substances can reduce the formation of free radicals in the body, protecting cells and molecules from damage. These free radicals play a role in aging and many types of diseases.
EGCG is one of the most powerful compounds in green tea. Research has tested its ability to help treat various diseases. It appears to be one of the main compounds that gives green tea its medicinal properties.
Green tea also has small amounts of minerals that can benefit your health.
Try to choose a higher quality brand of green tea, because some of the lower quality brands can contain excessive amounts of fluoride.
That being said, even if you choose a lower quality brand, the benefits still outweigh any risk.
SUMMARY: Green tea is loaded with polyphenol antioxidants, including a catechin called EGCG. These antioxidants can have various beneficial effects on health.
Green tea does more than just keep you alert, it might also help boost brain function.
The key active ingredient is caffeine, which is a known stimulant.
It doesn’t contain as much as coffee, but enough to produce a response without causing the “jittery” effects associated with taking in too much caffeine.
Caffeine affects the brain by blocking an inhibitory neurotransmitter called adenosine. This way, it actually increases the firing of neurons and the concentration of neurotransmitters like dopamine and norepinephrine.
Research has consistently shown that caffeine can improve various aspects of brain function, including mood, vigilance, reaction time, and memory.
However, caffeine isn’t the only brain-boosting compound in green tea. It also contains amino acid L-theanine, which is able to cross the blood-brain barrier.
L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has anti-anxiety effects. It also increases dopamine and the production of alpha waves in the brain.
Studies show that caffeine and L-theanine can have synergistic effects. This means that the combination of the two can have particularly powerful effects in improving brain function.
Because of the L-theanine and the small dose of caffeine, green tea might give you a much milder and different kind of “buzz” than coffee.
Many people report having more stable energy and being much more productive when they drink green tea compared to coffee.
Two separate review studies reported that caffeine may increase physical performance by approximately 11–12%
