10 shocking health benefits of green tea


10 health benefits of drinking green tea

1 | May improve health.

Green tea is more than just a green liquid . Many of the bioactive compounds in tea leaves make it the final beverage, containing large amounts of important nutrients, it is loaded with polyphenols like flavonoids and catechins, which function as powerful antioxidants.

These substances can reduce the formation of free radicals in the body, protecting cells and molecules from damage. These free radicals are known to play a role in aging and all kinds of diseases.


One of the most potent compounds in green tea is the antioxidant Epigallocatechin Gallate (EGCG), which has been studied to treat various diseases and may be one of the main reasons why green tea has such powerful medicinal properties.

Another Health benefit of consuming green tea is that it also has small amounts of minerals that are important for health.

Try to choose a higher quality brand, because some of the lower quality brands may contain excessive levels of fluoride; That said, even if you choose a lower quality brand, the health benefits of consuming green tea still far outweigh any risks.

2 | Benefits of green tea for brain health

Green tea does more than just keep you awake, it can also make you smarter . The key active ingredient is caffeine, which is a known stimulant, it does not contain as much as coffee, but it contains enough to produce a response without causing the “jitters” associated with too much caffeine.

What caffeine does in the brain is block an inhibitory neurotransmitter called adenosine . In this way, it actually increases the firing of neurons and the concentration of neurotransmitters such as dopamine and norepinephrine.

Caffeine has been intensively studied before and consistently leads to improvements in various aspects of brain function , including improved mood, alertness, reaction time, and memory;


However, one of the benefits of consuming green tea is that it contains more than just caffeine, it also has the amino acid L-theanine, which is capable of crossing 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, the combination of the two being particularly powerful in improving brain function.

Due to the L-theanine and the smaller dose of caffeine, green tea can 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 drinking green tea, compared to coffee.

3 | May improve performance

If you look at the ingredient list of any fat burner supplement , chances are that the green tea will be there.

This is because green tea has been shown to increase fat burning and increase metabolic rate, in human-controlled trials.


In a study of 10 healthy men, green tea increased energy expenditure by 4%. Another study showed that fat oxidation was increased by 17%, indicating that green tea can selectively increase fat burning.

However, I would like to point out that some studies on green tea do not show any increase in metabolism , so the effects may depend on the person.

Caffeine has also been shown to enhance physical performance by mobilizing fatty acids in tissues and making them available for use as energy.

In two separate review studies, caffeine has been shown to increase physical performance by 11-12%, on average, and by being included in tea, it enhances the health benefits of consuming green tea.

4 | Benefits of green tea for cancer

Cancer is caused by uncontrolled cell growth and is one of the leading causes of death in the world. It is well known that oxidative damage contributes to the development of cancer and that antioxidants can have a protective effect.

Green tea is an excellent source of powerful antioxidants , so it makes perfect sense that it can reduce your risk of cancer, there are even those who point out that within the health benefits of consuming green tea you can prevent some cancers such as:


Breast cancer : A meta-analysis of observational studies found that women who drank more green tea had a 22% lower risk of developing breast cancer, the most common cancer in women.

Prostate Cancer : One study found that men who drank green tea had a 48% lower risk of developing prostate cancer, which is the most common cancer in men.


Colorectal Cancer : The study of 69,710 Chinese women found that green tea drinkers had a 57% lower risk of colorectal cancer.

Multiple observational studies show that green tea drinkers are significantly less likely to get various types of cancer. It is important to note that it may be a bad idea to put milk in your tea as it can reduce the antioxidant value.

5 | May lower your risk of Alzheimer’s and Parkinson’s disease.

Not only can green tea improve brain function in the short term, it can also protect your brain in old age.

Alzheimer’s disease is the most common neurodegenerative disease in humans and one of the leading causes of dementia; while Parkinson’s disease is the second most common neurodegenerative disease and involves the death of dopamine-producing neurons in the brain.


Multiple studies show that the catechin compounds in green tea may have various protective effects on neurons in test tubes and animal models, potently lowering the risk of Alzheimer’s and Parkinson’s.

6 |  For dental health

The catechins in green tea have other biological effects as well. Some studies show that they can kill bacteria and inhibit viruses like the flu virus, potentially reducing the risk of infections.

The Streptococcus mutans is the main harmful bacteria in the mouth. Causing plaque formation and is a major contributor to cavities and tooth decay, studies show that the catechins in green tea can inhibit the growth of streptococcus mutans. Drinking green tea is associated with better dental health and a lower risk of cavities.

Another impressive health benefit of consuming green tea is that it can reduce bad breath.

7 | Benefits of green tea for diabetes.

Type II diabetes is a disease that has reached epidemic proportions in recent decades, afflicting nearly 300 million people around the world.

This disease involves having high levels of sugar in the blood in the context of insulin resistance or an inability to produce insulin; Studies show that green tea can improve insulin sensitivity and lower blood sugar levels


A study conducted on Japanese people found that those who drank more green tea had a 42% lower risk of developing type II diabetes.

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

8 | It can reduce your risk of cardiovascular disease.

Cardiovascular diseases, including heart disease and strokes, are the leading causes of death in the world.

Studies show that green tea can improve some of the main risk factors for these diseases, this includes total cholesterol, LDL cholesterol, and triglycerides .

Green tea also dramatically increases the antioxidant capacity of the blood , which protects LDL cholesterol particles from oxidation, which is part of the path to heart disease— Given the beneficial effects on risk factors, it is not surprising to see that green tea drinkers have up to a 31% lower risk of heart disease. Still doubt the benefits of consuming green tea?

9 | Benefits of green tea for weight loss

Since green tea can increase your metabolic rate in the short term , it makes sense that it could help you lose weight. Several studies show that green tea leads to a decrease in body fat, especially in the abdominal area.


One of these studies was a randomized controlled trial in 240 men and women that continued for 12 weeks. In this study, the group that consumed green tea had significant decreases in body fat percentage, body weight, waist circumference, and abdominal fat.

However, some studies do not show statistically significant increases in weight loss with green tea, so it is necessary to take it with a grain of salt, the important thing is that you do not stop discovering the health benefits of consuming green tea.

10 | Reduces the risk of cardiovascular disease

Of course, we all have to eventually die, that’s inevitable. However, since green tea drinkers are at a lower risk for cardiovascular disease and cancer, it makes sense that it could help you live longer .

In a study of 40,530 Japanese adults, those who drank the most green tea (5 or more cups per day) were significantly less likely to die over an 11-year period :

• Death from natural causes: 23% lower in women, 12% lower in men.

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


• Death from stroke: 42% less in women, 35% less in men.

Another study of 14,001 Japanese seniors ages 65 to 84 found that those who drank the most green tea were 76% less likely to die during the 6-year study period, will you keep waiting?
