What is Green Tea ?
Green tea is touted to be one of the healthiest beverages on the planet.
It’s loaded with antioxidants that have many health benefits, which may include:
- improved brain function
- fat loss
- protecting against cancer
- lowering the risk of heart disease
There may be even more potential health benefits.
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 epigallocatechin-3-gallate (EGCG). 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.
Green tea does more than just keep you alert, it may 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 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 (
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 (7,
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 may 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 with coffee.
If you look at the ingredients list for any fat burning supplement, chances are, green tea will be on there.
In one study involving 10 healthy men, taking green tea extract increased the number of calories burned by 4%. In another involving 12 healthy men, green tea extract increased fat oxidation by 17%, compared with those taking a placebo (
However, some studies on green tea don’t show any increase in metabolism, so the effects may depend on the individual and how the study was set up (
Cancer is caused by uncontrolled growth of cells. It’s one of the world’s leading causes of death.
Research has shown that oxidative damage can lead to chronic inflammation, which can lead to chronic diseases, including cancers. Antioxidants can help protect against oxidative damage (
Green tea is an excellent source of powerful antioxidants.
Research has linked green tea compounds with a reduced risk of cancer, including the following studies:
- Breast cancer. A comprehensive review of observational studies found that women who drank the most green tea had an approximately 20–30% lower risk of developing breast cancer, one of the most common cancers in women (
- Prostate cancer. One study observed that men drinking green tea had a lower risk of advanced prostate cancer (22).
- Colorectal cancer. An analysis of 29 studies showed that those drinking green tea were around 42% less likely to develop colorectal cancer (
Many observational studies indicate that green tea drinkers are less likely to develop several types of cancer, but more high quality research is needed to confirm these effects (24,
To get the most health benefits, avoid adding milk to your tea. Some studies suggest it can reduce the antioxidant value in some teas (
Not only can green tea improve brain function in the short term, it may also protect your brain as you age.
Parkinson’s disease is another common neurodegenerative disease and involves the death of dopamine-producing neurons in the brain.
Several studies show that the catechin compounds in green tea can have various protective effects on neurons in test tubes and animal models, possibly lowering the risk of dementia (
The rates of type 2 diabetes are increasing in recent decades. The condition now affects about 1 in 10 Americans (
Type 2 diabetes involves having elevated blood sugar levels, which may be caused by insulin resistance or an inability to produce insulin.
One study in Japanese individuals found that those who drank the most green tea had an approximately 42% lower risk of type 2 diabetes (
According to a review of 7 studies with a total of 286,701 individuals, tea drinkers had an 18% lower risk of diabetes (
Cardiovascular diseases, including heart disease and stroke, are the leading causes of death worldwide (45).
Given the beneficial effects on risk factors, it may not be surprising that people who drink green tea have up to a 31% lower risk of dying from a cardiovascular disease (
Given that green tea can boost the metabolic rate in the short term, it makes sense that it could help you lose weight.
One of these studies was a 12-week randomized controlled study involving 240 people with obesity.
In this study, those in the green tea group had significant decreases in body fat percentage, body weight, waist circumference, and belly fat, compared with those in the control group (
However, some studies don’t show a statistically significant increase in weight loss with green tea, so researchers need to perform further studies to confirm this effect (
Given that some compounds in green tea may help protect against cancer and heart disease, it makes sense that it could help you live longer.
In one study, researchers studied 40,530 Japanese adults over 11 years. Those who drank the most green tea — 5 or more cups per day — were significantly less likely to die during the study period (
- Death of all 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% lower in women, 35% lower in men
Another study involving 14,001 older Japanese individuals found that those who drank the most green tea were 76% less likely to die during the 6-year study period (57).
