10 Evidence-Based Benefits of Green Tea   

Green tea is often regarded as one of the world’s healthiest beverages. It’s high in antioxidants, which offer a variety of health advantages, including:

  • improved brain function
  • fat loss
  • protecting against cancer
  • lowering the risk of heart disease

There might be even more health advantages.

The following are ten potential health advantages of green tea.

#1 Contains healthy bioactive compounds

Green tea is more than simply a drink that keeps you hydrated. The green tea plant has a variety of beneficial substances that make their way into the finished beverage. Tea is high in polyphenols, which are natural substances with health advantages such as inflammation reduction and cancer prevention. Epigallocatechin-3-gallate is a catechin found in green tea (EGCG). Catechins are natural antioxidants that aid in the prevention of cell damage as well as provide other advantages. These chemicals can protect cells and molecules from harm by reducing the generation of free radicals in the body.

These free radicals contribute to aging and a variety of ailments. One of the most potent components of green tea is EGCG. Its capacity to assist treat a variety of ailments has been studied. It appears to be one of the most important chemicals in green tea that provides it its therapeutic benefits. Green tea also contains trace minerals that are beneficial to your health. Choose a higher-quality green tea since certain lower-quality products may contain too much fluoride. Even if you pick a lower-quality brand, the advantages still outweigh the risks.

SUMMARY         

Green tea is high in polyphenol antioxidants, such as EGCG (epigallocatechin gallate). These antioxidants may provide a variety of health benefits.

#2 May improve brain function

Green tea may assist increase brain function in addition to keeping you awake. Caffeine, a well-known stimulant, is the main active component. It doesn’t have as much caffeine as coffee, but it’s enough to elicit a response without generating the jittery effects that come with too much caffeine.

Caffeine impacts the brain by inhibiting adenosine, an inhibitory neurotransmitter. This enhances the neuronal activity and neurotransmitter concentrations such as dopamine and norepinephrine. Caffeine has been found to increase multiple areas of brain function, including mood, alertness, response time, and memory, in numerous studies. Green tea contains a variety of brain-boosting compounds in addition to caffeine. It also includes L-theanine, an amino acid that may pass the blood-brain barrier. L-theanine stimulates the inhibitory neurotransmitter GABA, which has anti-anxiety properties.

It also boosts dopamine levels and alpha wave generation. Caffeine and L-theanine have been shown to have synergistic effects in studies. As a result, combining the two can have a particularly potent effect on boosting brain function. Green tea may provide a much milder and different type of buzz than coffee due to the L-theanine and modest level of caffeine. When compared to coffee, many people report having more steady energy and being considerably more productive when they drink green tea.

SUMMARY

Green tea has a lower caffeine content than coffee, yet it still has enough to have an effect. It also includes the amino acid L-theanine, which can increase brain function when combined with caffeine.

#3 Increases fat burning

If you look at the ingredients list of any fat-burning product, you’ll almost certainly see green tea. This is because green tea has been shown to improve fat burning and metabolic rate in studies (12). Green tea extract boosted the number of calories burnt by 4% in research involving ten healthy males. Green tea extract enhanced fat oxidation by 17 percent in another study involving 12 healthy males, compared to those who took a placebo.

However, some research on green tea has found no improvement in metabolism, suggesting that the benefits may vary depending on the individual and how the study was conducted. Caffeine can also help you perform better in the gym by mobilizing fatty acids from your adipose tissue and making them accessible for energy. Caffeine has been shown in two distinct review studies to boost physical performance by 11–12%..

SUMMARY

Although not all studies agree, green tea may raise metabolic rate and fat burning in the short term.

#4 Antioxidants may lower the risk of some cancers

Cancer is a disease caused by uncontrolled cell development. It is one of the major causes of death around the globe. Oxidative damage has been linked to chronic inflammation, which has been linked to chronic illnesses such as cancer. Antioxidants can aid in the prevention of oxidative damage.

Green tea is high in antioxidants and is a great source of them. Green tea components have been associated to a lower risk of cancer in studies such as these:

Breast cancer is a disease that affects women. According to a meta-analysis of observational studies, women who drank the greenest tea had a 20–30 percent decreased risk of breast cancer, one of the most frequent diseases in women.

Prostate cancer is a disease that affects men. Men who drank green tea had a decreased chance of advanced prostate cancer, according to one research (22).

Colorectal cancer is a kind of cancer that affects the colon. Green tea drinkers were 42 percent less likely to acquire colorectal cancer, according to a review of 29 research.

Green tea users are less likely to acquire numerous forms of cancer, according to several observational studies, but additional high-quality research is needed to corroborate these findings.

Avoid adding milk to your tea to obtain the maximum health advantages. According to certain research, it may lower the antioxidant value of various teas.

SUMMARY

Green tea contains potent antioxidants that may help to prevent cancer. Green tea consumers had a decreased risk of many forms of cancer, according to multiple studies.

#5 May protect the brain from aging

Green tea has been shown to increase brain function in the near term as well as protect the brain as it ages. Alzheimer’s disease is a widespread neurological illness that is the leading cause of dementia among seniors. Another prevalent neurodegenerative illness is Parkinson’s disease, which is characterized by the loss of dopamine-producing neurons in the brain. Green tea catechin chemicals have been shown in several studies to have diverse protective effects on neurons in test tubes and animal models, potentially decreasing the incidence of dementia.

SUMMARY

Green tea’s bioactive components may have a variety of brain-protective properties. They may lower the risk of dementia, a prevalent neurological disease that affects the elderly.

#6 May reduce bad breath

Green tea catechins are also beneficial to dental health. Catechins have been shown in test tubes to inhibit the development of bacteria, potentially decreasing the risk. Streptococcus mutants is a common oral bacteria. It contributes to the production of plaque and is a major cause of cavities and tooth decay. Green tea catechins have been shown to prevent the development of oral bacteria in the lab, but there is no proof that drinking green tea has the same. Green tea, on the other hand, appears to help with foul breath.

SUMMARY

Green tea catechins may prevent bacterial development in the mouth, lowering the incidence of foul breath.

#7 May help prevent type 2 diabetes

In recent decades, the prevalence of type 2 diabetes has risen. About one out of every ten Americans today has the disease. Elevated blood sugar levels are a symptom of type 2 diabetes, which can be caused by insulin resistance or an inability to make insulin. Green tea has been shown in studies to improve insulin sensitivity and lower blood sugar levels. A study of Japanese people revealed that those who drank the greenest tea had a 42 percent decreased chance of developing type 2 diabetes. Tea users had an 18 percent decreased risk of diabetes, according to a study of seven research including 286,701 people.

SUMMARY           

Green tea has been shown in several controlled trials to elicit minor blood sugar decreases. It may also help to reduce the chance of developing type 2 diabetes.

#8 May help prevent cardiovascular disease

The major causes of mortality globally are cardiovascular disorders, such as heart disease and stroke (45). Green tea has been shown in studies to improve several of the primary risk factors for these illnesses, such as total cholesterol and LDL (bad) cholesterol levels (46). Green tea also boosts the blood’s antioxidant capacity, which protects LDL particles from oxidation, which is one of the factors that lead to heart disease (47, 48). Given the positive impact on risk variables, it’s no surprise that green tea drinkers had a 31 percent decreased chance of dying from cardiovascular disease.

SUMMARY          

Green tea has been shown to reduce total and LDL (bad) cholesterol while also protecting LDL particles from oxidation. Green tea drinkers had a decreased risk of cardiovascular illness, according to studies.

#9 It’s possible that it will assist you in losing weight.

Given that green tea can temporarily increase metabolic rate, it makes it plausible that it could aid weight loss. Green tea has been shown in several trials to aid in the reduction of body fat, particularly in the stomach area. One of these research involved 240 obese patients in a 12-week randomized controlled trial.

When compared to the control group, those in the green tea group had significantly lower body fat percentage, body weight, waist circumference, and belly fat. However, other studies have found that green tea does not cause a statistically significant increase in weight reduction, therefore further study is needed to establish this benefit (55Trusted Source).

SUMMARY

Green tea has been linked to weight reduction in several studies. It may be especially beneficial for lowering harmful abdominal fat.

#10 It’s possible that it’ll help you live longer.     

Green tea has several components that may help protect against cancer and heart disease, so it’s not surprising that it might help you live longer. Researchers evaluated 40,530 Japanese people for 11 years in one study. Those who drank the greenest tea — 5 or more cups per day — had a lower risk of dying throughout the trial:

Women have a 23% lower death rate than males, and men have a 12% lower death rate.

Women had a 31% reduced risk of dying from heart disease, whereas males have a 22% lower risk.

Stroke mortality is 42 percent lower in women and 35 percent lower in males.

Another research of 14,001 elderly Japanese people revealed that those who consumed the greenest tea were 76 percent less likely to die over the course of the study’s six years (57).

SUMMARY

Research suggests that those who consume green tea live longer than those who do not.

In conclusion, green tea may provide a variety of health advantages.

Consider making green tea a regular part of your life to help you feel better, lose weight, and reduce your risk of chronic illnesses.
