16 Benefits of drinking Green Tea: A Comprehensive Analysis

Green tea leaves contain various compounds, nutrients, vitamins, and minerals, but these elements become highly diluted when steeped in water. As a result, the green tea you drink is primarily water with little to no macronutrient content. 

However, the bioactive compounds inside provide numerous green tea benefits. The levels of these compounds are affected by the type of tea used, steeping time, and water temperature. 

Many experts recommend people steep the tea in warm or ambient water for 2-3 minutes.

Green tea is also a moderate source of caffeine, with about a quarter of the amount found in coffee. Additionally, it contains polyphenols, a potent type of antioxidant.

It may help maintain cognitive function as you age

Green tea may not only enhance brain function in the short term, but it also safeguards your brain as you age.

Alzheimer’s is a prevalent neurodegenerative condition that causes dementia in many older individuals. Likewise, Parkinson’s disease is another neurodegenerative ailment that results in the demise of dopamine-generating neurons in the brain.

Studies suggest that catechins in green tea may guard against neuron damage and reduce dementia risk.

SUMMARY: Green tea contains bioactive compounds that can provide multiple protective benefits for the brain, including a potential reduction in the risk of dementia. This prevalent neurodegenerative condition affects many older adults.

It may be effective in combating bad breath

Green tea has been shown to have antibacterial properties that can help prevent tooth decay and improve oral health.

One common bacterium in the mouth is Streptococcus mutants, which cause plaque formation and contribute to cavities and tooth decay. Research shows that the catechins in green tea can inhibit the growth of oral bacteria in the lab. 

Despite ongoing research, it is unclear whether green tea has the same effects. Nonetheless, some evidence points to its potential to alleviate bad breath.

SUMMARY: Green tea contains catechins that could hinder the proliferation of bacteria inside the mouth, decreasing the likelihood of experiencing unpleasant breath.

May assist in staving off type 2 diabetes

Research indicates green tea’s compounds can promote insulin sensitivity and regulate blood sugar, potentially reducing type 2 diabetes risk.

Recent studies have shown that green tea could improve insulin sensitivity and reduce blood sugar levels. For example, a Japanese individual survey revealed that those who drank the greenest tea had a lower risk of type 2 diabetes by approximately 42%.

Furthermore, a review of seven studies involving 286,701 participants found that regular tea drinkers had an 18% lower risk of developing diabetes.

SUMMARY: Certain controlled studies have indicated that green tea could lead to slight decreases in blood sugar levels and a reduced risk of type 2 diabetes.

Might protect against cardiovascular illness

Some studies have shown that green tea may help reduce the risk of heart disease. Green tea contains compounds that help lower LDL cholesterol (the “bad” cholesterol) and triglycerides, which can help improve heart health.

As far as I know, green tea consumption may reduce cardiovascular disease risk factors, including high cholesterol levels. Cardiovascular diseases are less likely to occur suddenly thanks to their antioxidant content that prevents “bad” cholesterol metabolism.

Amazingly, people who drink green tea could have up to a 31% lower risk of dying from cardiovascular diseases, considering how simple and delicious it is to add green tea to our daily routine. So, why not give it a try? Your heart might just thank you for it!

SUMMARY: Studies have demonstrated that consumption of green tea can reduce both overall and LDL (commonly known as “bad”) cholesterol levels, in addition to guarding against the oxidation of LDL particles. Furthermore, individuals who consume green tea regularly have been shown to have a lower likelihood of developing cardiovascular disease.

It can aid in weight loss

Green tea has been shown to have a small but significant effect on weight loss. Green tea contains compounds that can help boost metabolism and increase fat burning.

Multiple studies indicate that green tea might help reduce body fat, especially in the belly area.

One of the studies that caught my attention was a 12-week randomized controlled trial with 240 people who had obesity. The participants who drank green tea experienced a significant reduction in body fat percentage, body weight, waist circumference, and belly fat compared to those in the control group.

However, it’s important to note that not all studies significantly increase weight loss with green tea. Further research is needed to confirm its effectiveness in aiding weight loss.

SUMMARY: Particular research suggests that consumption of green tea can result in an augmentation of weight loss, with a potential for noteworthy reduction of hazardous visceral fat, specifically.

  • Compared to men, women have a 23% lower risk of dying from any cause.
  • Additionally, women have a 31% lower risk of heart disease and a 42% lower risk of dying from stroke. 
  • In contrast, men have a 12% lower risk of dying from any cause, a 22% lower risk of dying from heart disease, and a 35% lower risk of dying from stroke.

14,001 elderly Japanese sippers proved that those guzzling the most green tea had a 76% lower risk of death in a 6-year study.

SUMMARY: Research indicates that individuals who consume green tea could have a greater lifespan than those who do not.

Brewing Up Relief: How Green Tea Fights Inflammation

I learned that green tea contains anti-inflammatory properties based on human clinical studies and experiments on cells and animals. Its primary component, epigallocatechin-3-gallate (EGCG), has also been found to have anti-inflammatory effects. A review of these studies demonstrated these effects quite nicely.

The benefits of green tea

Furthermore, I discovered a 2019 analysis that showed how tea extracts can be used in cosmetics to promote anti-inflammatory responses when applied topically. According to the researchers, solutions containing tea extracts can also improve skin microcirculation in affected areas.

SUMMARY: Green tea contains anti-inflammatory properties due to its primary component, EGCG. Human clinical studies and experiments on cells and animals have shown its anti-inflammatory effects. Tea extracts can also be used in cosmetics to promote anti-inflammatory responses and improve skin microcirculation in affected areas.

Reduce Your Stroke Risk

According to research, drinking and making green tea (how to make green tea) regularly appears to be linked to a lower risk of stroke. The American Heart Association (AHA) conducted a study that adding green tea to your daily diet could significantly reduce stroke risk.

It Helps For Alzheimer’s disease

Now, want to know about green tea’s secret weapon against Alzheimer’s? Scientists in 2011 studied the colon-available green tea extract (CAGTE) on crucial brain proteins using neuron cells as a test-tube model.

Can green tea protect cells from damage? That’s what we tested by studying CAGTE, the good stuff in green tea that sticks around after digestion. Indeed, it fights off free radicals and beta-amyloid peptides. These compounds are believed to contribute to the development of Alzheimer’s disease.

The study showed that CAGTE could protect the cells from damage caused by these harmful compounds at high concentration levels. However, it’s important to note that the concentration in the experiments was much more significant than naturally found in the human body.

SUMMARY: The study found that CAGTE could protect neuron cells from damage caused by free radicals and beta-amyloid peptides at high concentration levels. However, the concentration in the experiments was much higher than naturally found in the human body.

It Can Handle The Genital Wart

The FDA has approved a topical treatment made from green tea extract to tackle outbreaks of genital warts. It’s worth noting that this ointment is only available via prescription, and its effectiveness for patients can range from 24% to 60%.

Can Decrease Blood Pressure

Many experts claim that potential green tea benefits are for heart health, such as reducing cholesterol levels and lowering blood pressure. According to a 2020 analysis of 1,697 people published in Medicine, green tea consumption significantly decreased blood pressure, especially in individuals with high blood pressure and a greater risk of cardiovascular disease.

CDC warns that high blood pressure damages arteries, leading to dangerous plaque buildup and narrowed blood flow to the heart and brain. When left untreated, high blood pressure can also result in kidney failure.

Green tea’s power to lower blood pressure lies in its potent antioxidants, which ease inflammation, widen blood vessels, and boost blood flow. However, most studies analyzed in the 2020 study only lasted between three and sixteen weeks, and it is unclear whether drinking green tea for longer periods (best time to drink green tea) can improve blood pressure levels.

SUMMARY: Green tea has potential heart health benefits, such as lowering cholesterol and blood pressure. A 2020 analysis of 1,697 people found that it significantly reduced blood pressure, likely due to its antioxidants that widen blood vessels and reduce inflammation. Accordingly, the long-term green tea consumption effects on blood pressure still need to be clarified, as most studies were short-term.

Keep Your Bone Health In Safety

Drinking green tea could help prevent the loss of bone mass, especially in postmenopausal women at a greater risk of developing osteoporosis. In postmenopausal Korean women, green tea preserves bones! 

Nutrients published a study in 2022 including 6,500 females who drank three glasses per day. Results? Compared to non-drinkers or people who drank less than one cup per day for a year, there was reduced bone mass loss in the spine and thigh.

When bone mass reduces, osteoporosis can increase the chances of osteoporosis, leading to fragile bones and hip, spine, or wrist fractures. According to the National Library of Medicine, postmenopausal women are more susceptible to this condition.

The high antioxidant concentration in green tea can help prevent bone loss and promote bone formation. This may explain why a 2017 analysis published in Medicine linked tea consumption to reduced osteoporosis.

SUMMARY: Drinking green tea can prevent bone loss and reduce osteoporosis in postmenopausal women, as shown by a study in Nutrients. Green tea’s antioxidants can help promote bone formation, according to a 2017 analysis in Medicine.

The Hidden Risks of Drinking Green Tea: What You Need to Know

As an adult who enjoys drinking green tea, I’ve found that it generally doesn’t cause any side effects. However, I want to be aware of its potential risks and complications.

  • Firstly, drinking green tea might not be a good idea if you’re very sensitive to caffeine. It could lead to problems like insomnia, anxiety, irritability, nausea, or an upset stomach.
  • Secondly, I’ve read that high concentrations of green tea extract could harm the liver in rare cases. However, most research indicates that these instances are idiosyncratic reactions and are not directly caused by green tea.
  • Thirdly, combining green tea with other stimulants like drugs could increase blood pressure and heart rate.

It’s important to note that green tea supplements aren’t regulated by the FDA, which means they may contain substances that are unsafe or have unproven benefits. I recommend checking with a doctor before starting any herb or supplement regimen.

Key Things To Consider For Consuming Green Tea

When it comes to enjoying my green tea, whether hot or chilled, I always keep a few things in mind:

  • I like to buy naturally decaffeinated green tea because a cup of regular green tea contains between 20 and 50 milligrams of caffeine. This may not be ideal for those who are sensitive to caffeine, as it can cause anxiety, a fast heart rate, and jitters, according to the Food and Drug Administration (FDA). However, removing the caffeine may lower the antioxidant content, as stated in a 2016 Food Chem article, though research on this topic is mixed.
  • When I sweeten my green tea, I will be mindful of the amount of sweetener I add. The American Heart Association (AHA) recommends that women consume six teaspoons of added sugar daily and men no more than nine teaspoons. Too much sugar can lead to weight gain, type 2 diabetes, and heart disease.
  • Finally, I like to get creative with my green tea! While I enjoy drinking it independently, I also use it in smoothies, oatmeal, or boiling rice and steaming vegetables. There are so many ways to enjoy this tasty and healthy beverage!
