Green tea is used a lot like making drinking tea or grinding green tea into a powder for use in cooking. Not only that, green tea also has many health benefits. So what does green tea do?
Green tea is “advertised” as one of the healthiest drinks on the planet. It contains antioxidants, and has many health benefits, including:
– Improve brain function
– Eliminate fat
– Protect the body, help fight cancer
– Reduce the risk of heart disease
Also green tea may have even more potential health benefits! But is drinking green tea every day good? The answer is yes. You can drink 3-5 cups of green tea every day, depending on your fitness.
The benefits of green tea for health
1. Contains healthy bioactive compounds
Green tea is not just a beverage. So what does green tea do? This water contains a range of healthy compounds, including:
Polyphenols, are natural compounds that have health benefits, such as reducing inflammation and helping fight cancer.
– Epigallocatechin-3-gallate (EGCG), a catechin. Catechins are natural antioxidants, which help prevent cell damage and provide other benefits.
– A small amount of minerals.
These substances can reduce the formation of free radicals (cause aging and many other diseases) in the body, protecting cells and molecules from damage.
2. Improve brain function
Green tea not only helps you stay awake but can also help boost brain function. It is thanks to caffeine.
This stimulant is not as much as in coffee, but it is enough to help clear the mind, without causing the restless effects of drinking coffee.
Caffeine affects the brain by blocking an inhibitory neurotransmitter, called adenosine. In this way, it increases the activity of nerve cells and the concentration of neurotransmitters, such as dopamine and norepinephrine.
In addition, green tea also contains L-theanine, which is considered a “double card” of caffeine. This substance increases the activity of the neurotransmitter that inhibits GABA – has an anti-anxiety effect. It also increases dopamine and produces alpha waves in the brain. The combination of both L-theanine and caffeine has a particularly strong effect on improving brain function.
3. Support fat burning
Studies have shown that green tea can increase fat burning, and speed up metabolism.
In a study of 10 healthy men, drinking green tea extract increased calorie burn by 4%. In another study involving 12 healthy men, green tea extract was able to increase fat oxidation by 17%, compared to those who took a placebo.
4. Reduce the risk of some cancers
What does green tea do? Certainly the ability to reduce the risk of some cancers is certainly included. Cancer is caused by uncontrolled growth of cells, and is one of the leading causes of death in the world.
The study looked at the powerful antioxidant properties of green tea compounds for a number of carcinogenic risks, including the following:
– Breast cancer: A comprehensive review of observational studies shows that women who drink the most green tea have a 20% – 30% lower risk of breast cancer.
Prostate cancer: An observational study found that men who drank green tea had a lower risk of prostate cancer.
– Colorectal cancer: An analysis of 29 studies found that green tea drinkers had a 42% lower risk of colorectal cancer.
To get the most health benefits, you should not add milk to tea. Some studies show that it can reduce the antioxidant value in some teas.
5. Protect the brain from aging
Not only can green tea improve brain function in the short term, it can also protect the brain as you get older.
Alzheimer’s disease is a common neurodegenerative disease and is the most common cause of dementia in older adults. Parkinson’s disease is another common neurodegenerative disease that kills the dopamine-producing neurons in the brain.
Several studies show that the catechin compounds in green tea have different protective effects on in vitro and animal neurons, which may reduce the risk of dementia.
