10 The Benefits of Green Tea on Health

Green tea is used a lot like making drinking tea or grinding green tea into a powder for use in cooking. Not only that, but 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 - Improving brain function - Eliminating fat - Protecting the body, helping to fight cancer - Reducing the risk of disease Heart 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 physical strength. Here are 10 The Benefits of Green Tea on Health.

1. Green Tea Contains healthy bioactive compounds

Green tea is not just a beverage.

So what does green tea do? It contains a range of healthy compounds, including - Polyphenols, which are natural compounds that have health benefits, such as reducing inflammation and helping fight cancer. - Epigallocatechin-3-gallate (EGCG), catechin.

Catechins are natural antioxidants, which help prevent cell damage and provide other benefits. - A small number of minerals.

These substances can reduce the formation of free radicals (cause aging and many other diseases) in the body, protecting cells and particles from damage.

2. Green Tea 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 anti-tumor effects.

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. Green Tea Support fat burning

Studies have shown that green tea can increase the fat-burning process while increasing the metabolism rate.

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. Green Tea Reducing the risk of some cancers

Does green tea have any effect?

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.

Green tea is an excellent source of powerful antioxidants.

The study looked at the powerful antioxidant properties of green tea compounds for several cancer risk factors, including the following: - Breast cancer: A comprehensive review of the important studies

The study found that women who drank the greenest tea had 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 showed 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 your brain from aging

Green tea can not only improve brain function in a short time, it can also protect your 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.

Some studies show that the catechin compounds in green tea have different protective effects on in vitro and animal neurons, which can reduce the risk of dementia.

6. Reducing bad breath

The catechins in green tea are also beneficial for dental health.

Test-tube studies suggest that catechins may prevent the growth of bacteria, potentially reducing the risk of infection.

Streptococcus mutans is a common bacteria in the mouth. It forms plaque and is a leading cause of tooth decay.

Studies show that the catechin in green tea can inhibit the growth of oral bacteria in the lab, but there is no evidence that drinking green tea has the same effect.

However, there is some evidence that green tea may reduce bad breath.

7. Preventing type 2 diabetes

The rate of type 2 diabetes has been increasing in recent decades.

This disease currently affects about 1 in 10 Americans. Type 2 diabetes occurs when blood sugar levels rise, either due to insulin resistance or the inability to produce insulin.

Studies show that green tea can improve insulin sensitivity and lower blood sugar. A study in Japanese individuals found that those who drank the greenest tea had a 42% lower risk of type 2 diabetes.

According to a review of 7 studies with a total of 286,701 individuals, green tea drinkers had an 18% lower risk of diabetes.

8. Prevent cardiovascular disease

Cardiovascular diseases, including heart disease and stroke, are the leading cause of death worldwide.

Studies show that green tea may improve several key risk factors for these diseases, including improving total cholesterol and LDL (harmful) levels.

Green tea also boosts the antioxidant capacity of the blood, helping to protect LDL particles from oxidation - part of the pathway to heart disease.

So it's not surprising that green tea drinkers have a 31% lower risk of dying from cardiovascular disease.

9. Support sun reduction

Because green tea helps speed up the metabolism in a short time, it means that it can help you reduce the sun.

Some studies show that green tea can help reduce body fat, especially in the belly area.

 One of these studies was done in 12 weeks with 240 obese people. Those in the green tea drinking group had a significant reduction in their fat percentage, body weight, waist circumference, and abdominal fat, compared to those in the group who were strictly controlled diet.

However, some studies do not show a significant reduction in green tea, so scientists need to conduct further studies to confirm this effect.

10. Longevity

Because of some compounds in green tea help protect the body from cancer and heart disease, it means that it also extends the life of people who drink green tea regularly.

In one study, researchers followed 40,530 Japanese over 11 years old. 

Those who drank the greenest tea - 5 or more cups a day - were significantly less likely to die during the study period:

- All-cause mortality: 23% lower in women, 12% lower In men 

- Death from heart disease: 31% lower in women, 22% lower in men 

- Deaths from stroke: 42% lower in women, 35% lower in men A study Another reference to 14,001 elderly fish in Japan showed that those who drank the greenest tea had a 76% lower mortality rate during the 6-year study period.
