What is green tea?

To best understand green tea, we need to look at tea in general. Most people drink black tea or its variations. Others like to sip on oolong tea, and some prefer the white variety of tea.
Tea comes from the leaves of the Camellia sinensis bush. The plant comes in two varieties. One grows in China and is used for green and white tea. The second type of shrub is found in India and is used to make both oolong and black tea.
Of the four types of tea, green tea contains the most flavonoids, which are plant-based antioxidant chemicals. Green tea is the least oxidized when processed, and is therefore considered the most beneficial.

Health Benefits of Green Tea:

Improve brain functioning

Green tea does more than just keep you alert, it can also help boost brain function. The major active ingredient is caffeine, which is a known stimulant. It doesn’t have as much coffee, but enough to trigger a reaction without causing the irritating effects associated with consuming too much caffeine.
Caffeine affects the brain by blocking an inhibitory neurotransmitter called adenosine. In this way, it increases the firing of neurons and the concentration of neurotransmitters such as dopamine and norepinephrine. Research has consistently shown that caffeine can improve various aspects of brain function, including mood, alertness, reaction time and memory.

Increases Rate of Fat Burning

If you look at the list of ingredients for any fat burning supplement, chances are, green tea will be there. This is because, according to research, green tea can increase fat burning and increase the metabolic rate. In one study involving 10 healthy men, taking green tea extract reduced the number of calories by 4%. increased. In another 12 healthy men, there was a 17% increase in green tea extract compared to those taking a placebo. However, some studies on green tea show no increase in metabolism, so the effect may depend on the individual and how the study was set up.

Act as Anti aging

Not only can green tea improve brain function in the short term, it can also protect your brain as you age. Alzheimer’s disease is a common neurodegenerative disease and the most common cause of dementia in older adults. Parkinson’s disease is another common neurodegenerative disease and involves the death of dopamine-producing neurons in the brain. Several studies suggest that the catechin compounds in green tea may exert various protective effects on neurons in test tubes and animal models, potentially reducing the risk of dementia.

Improvement in quality of breath

The catechins in green tea also have benefits for oral health. Test-tube studies suggest that catechins may suppress bacterial growth, possibly reducing the risk of infection. Streptococcus mutans is a common bacterium in the mouth. It causes plaque buildup and is a major contributor to cavities and tooth decay. Studies indicate that the catechins in green tea may inhibit the growth of oral bacteria in the lab, but no evidence shows that drinking green tea has the same effect. However, there is some evidence that green tea can reduce bad breath.

Prevent from Type-2 Diabetes

Rates of type 2 diabetes have been increasing in recent decades. The condition now affects 1 in 10 Americans. Type 2 diabetes has elevated blood sugar levels, which may be due to insulin resistance or an inability to produce insulin. Studies show that green tea can improve insulin sensitivity and lower blood sugar levels.

Helps in weight loss

Given that green tea can boost metabolic rate in the short term, it makes sense that it could help you lose weight. Several studies show that green tea can help reduce body fat, especially in the abdominal area. 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 reductions in body fat percentage, body weight, waist circumference and abdominal fat, compared to those in the control group. However, some studies do not show a statistically significant increase in weight loss with green tea, so researchers need to conduct further studies to confirm this effect.

Helps in live longer

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.

Prevent From Cancer

According to the National Cancer Institute, the polyphenols in tea have been shown to reduce tumor growth in laboratory and animal studies and may protect against damage caused by ultraviolet UVB radiation. Cancer rates are increased in countries where green tea consumption is high. There is little, but it is impossible to say for sure whether it is green tea that prevents cancer in these particular populations or other lifestyle factors.

Reduces Cholesterol

A 2011 analysis of studies published in Trusted Source found that green tea consumption, either as a beverage or in capsule form, was associated with significant but modest reductions in total and LDL or “bad” cholesterol.

Inflammatory skin diseases

A 2007 study concluded that green tea may hold promise as a new treatment for skin disorders. Assigned sources such as psoriasis and dandruff. The researchers studied an animal model for inflammatory skin diseases, which are often characterized by patches of dry, red, flaky skin due to inflammation and overproduction of skin cells. Those treated with green tea showed slower growth of skin cells and the presence of a gene that controls the life cycle of cells.

Side Effect of Green Tea:

There are no known side effects or contraindications for drinking green tea for adults. However, the following risks or complications should be clarified:

Caffeine sensitivity

People with severe caffeine sensitivity may experience insomnia, anxiety, irritability, nausea or upset stomach.

Blood thinners

Those taking blood thinners (anticoagulants) such as Coumadin/warfarin should drink green tea because of its vitamin K content. It also recommended avoiding green tea and aspirin, as both of them reduce the clotting effectiveness of platelets.

Other stimulants

If taken with stimulant medications, green tea can increase blood pressure and heart rate. Green tea supplements contain high levels of active substances that can trigger side effects and interact with other herbs, supplements, or medications.
Green tea supplements are unregulated by the FDA and may contain other substances known to be unsafe or with unproven health benefits. Always check with a doctor before starting any herb or supplement regimen. In particular, women who are pregnant or breast-feeding, with heart problems or high blood pressure, kidney or liver problems, stomach ulcers or anxiety disorders should not take green tea supplements or extracts.

How much green tea should you drink a day?

Studies have not been conclusive on how much green tea to drink in a day to get maximum benefits. It really depends on the individual and their own personal health. Green tea in varying amounts every day will benefit you in many ways. For example, in controlled studies, people who drank one to three cups each day had a lower risk of stroke and heart disease than subjects who drank less than one cup. And colon cancer was less likely to develop in women who consumed more than 5 cups daily.

What happens if someone takes green tea everyday?

Excessive drinking of green tea can lead to stomach problems, diarrhea and even iron deficiency. You may also experience insomnia. Therefore, drink it in limited quantities as green tea in excess can prove to be harmful to your health.

How much green tea should be taken in a day

Drinking three to five cups of green tea per day seems to be optimal to reap the most health benefits. Too high a dosage can be problematic for some, but in general, the benefits of green tea outweigh its risks. In fact, drinking more green tea can significantly improve your health.

What is the best time to drink green tea?

Certain compounds in green tea can inhibit the absorption of iron and other minerals, so it is best to drink it between meals. Also, the amount of caffeine consumed before bedtime can cause sleep disturbances.

Does green tea reduce belly fat?

Green tea can help you lose fat, especially harmful belly fat. When it comes to the actual pounds to be lost, green tea has relatively little effect. Although many studies show that people do indeed lose weight, there are some studies that have shown no effect.

Can green tea help you sexually?

Green tea is delicious, but it also helps in the bedroom. Green tea is particularly high in catechins, a natural phenol and antioxidant that promotes blood flow to the sex organs.


Native to China and India, green tea has been globally consumed and hailed for its health benefits for centuries, but has only recently gained popularity in the United States. Tea is the most consumed beverage in the world behind water. However, 78 percent of the tea consumed worldwide is black and only 20 percent is green.
All types of tea, except herbal teas, are brewed from the dried leaves of the Camellia sinensis bush. The level of oxidation of the leaves determines the type of tea. Green tea is made from unoxidized leaves and is one of the less processed types of tea. Therefore it contains the most antioxidants and beneficial polyphenols.
