Key Takeaways

  • Green tea has numerous benifits
  • It helps in lowering the blood pressure
  • The antioxidants can help oxidative damage and thus reduces the risk of several cancers

Green tea is loaded with antioxidants is thought to be a health-promoting beverage. It helps prevent cellular damage, lowers the risk of heart disease, and increases immunity. Just like other non-herbal teas, it is made from leaves of the Camellia Sinensis plant but is less processed. The delicate processing techniques make it rich in beneficial polyphenols.

The benefits of green tea range from increasing alertness to the prevention of cancer, although few of them require more evidence to support it.

Benefits of Green Tea:

Here is a list of possible health benefits of Green Tea:

According to common perception, green tea is one of the world's healthiest beverages.

It is packed with antioxidants, which provide a wide range of health advantages, such as:

  • Enhance mental performance
  • Slim down
  • Prevents cancer
  • Decreasing the likelihood of contracting heart diseases

Even more advantageous impacts on health could exist. Some of them are as follows:

Contains Beneficial Bioactive Ingredients

  • Green tea is more than simply a refreshing drink.
  • The green tea plant has a number of useful compounds that make their way into the finished product.
  • Green Tea has a lot of polyphenols, which are natural compounds that have health benefits, including reducing inflammation and preventing cancer.
  • Green tea contains the catechin epigallocatechin-3-gallate (EGCG). Catechins are antioxidants that are naturally found and prevent cell damage and provide extra benefits.

Brain Function May Be Improved

  • Green tea may help boost brain function while also keeping you awake. Caffeine is the main active component and is a well-known stimulant.
  • Adenosine, an inhibitory neurotransmitter, is suppressed by caffeine, which impacts the brain.
  • This increases neuronal activity and neurotransmitter levels, such as dopamine and norepinephrine.
  • However, caffeine isn't the only ingredient in green tea that helps the brain. It also includes L-theanine, an amino acid that may cross the blood-brain barrier.

Enhances Fat Burning

  • Any fat-burning product's ingredient list nearly invariably includes green tea.
  • This is because studies have found that green tea can increase metabolic rate and fat burning.
  • Green tea extract boosted the number of calories burnt by 4% in one research, including ten healthy males. In another study involving 12 healthy males, green tea extract boosted fat oxidation by 17% compared to a control.
  • According to certain research, green tea may increase metabolic rate and fat burning in the short term.

Some Cancers May Have A Lower Risk Due To Antioxidants

Green tea chemicals have been associated with a lower risk of cancer in studies such as the ones below:

1. Cancer of the breast

A meta-analysis of observational studies found that women who drank green tea had a 20-30% decreased chance of acquiring breast cancer, one of the most frequent malignancies in women

2. Cancer of the prostate

According to one study, males who drank green tea had a decreased chance of developing advanced prostate cancer.

3. Cancer of the colon

A review of 29 research found that those who drank green tea were 42% less likely to acquire colorectal.

Avoid adding milk to your tea to get the best benefits of green tea. According to certain studies, it may reduce the antioxidant content of some teas.

Green Tea Will Prevent The Brain From Aging

  • Green tea not only enhances brain function in the short term but may also help protect your brain as you age.
  • Alzheimer's disease is the most frequent cause of dementia in older persons and a common neurodegenerative illness.
  • Parkinson's disease is another prevalent neurodegenerative illness that causes dopamine-producing neurons in the brain to die.
  • Several studies have found that the catechin chemicals in green tea can have various neuroprotective effects in animal models and test tube, potentially decreasing the incidence of dementia.

Reduces Foul Breath

  • Catechins from green tea are also beneficial for your teeth.
  • Catechins have been shown in laboratory experiments to inhibit the development of bacteria, potentially decreasing the risk of illness
  • Streptococcus mutans is a common oral bacteria. It promotes plaque formation and is a significant cause of cavities and tooth decay.
  • Green tea catechins have been shown in lab studies to prevent the development of oral bacteria, but there is no proof that drinking green tea has the same impact.
  • Green tea, on the other hand, appears to aid in the treatment of bad breath.

Helpful In Preventing Type 2 Diabetes

  • Type 2 diabetes has become more prevalent in recent decades. Today, one out of every ten Americans suffers from the disease.
  • Type 2 diabetes is characterized by high blood sugar levels caused by insulin resistance or an inability to make insulin.
  • Studies prove that green tea can improve insulin sensitivity and lowers blood sugar levels.
  • According to one research on Japanese people, those who drank green tea had a 42% decreased chance of developing type 2 diabetes.

Could Aid in Weight Loss

  • Given that green tea can improve metabolic rate temporarily, it stands to reason that it might help with weight reduction.
  • Several studies indicate that green tea may aid in the reduction of body fat, particularly in the stomach area.
  • One of these researches involved 240 obese patients in a 12-week randomized controlled trial.
  • When compared to the control group, individuals in the green tea group experienced substantial reductions in body fat percentage, waist circumference, body weight, and belly fat.
  • However, other studies do not indicate a statistically significant increase in weight reduction with green tea. Therefore further study is required to establish this benefit.

Green Tea Might Help You Live a Longer Life

  • Given that certain green tea chemicals may help protect against cancer and heart disease, it stands to reason that they may help you live longer.
  • Over the course of 11 years, researchers investigated 40,530 Japanese people in one study. Those who drank green tea — 5 or more cups per day — had a considerably lower risk of dying.
  • All-cause mortality is 23% lower in women and 12% lower in males.
  • Women had a reduced risk of of dying of 31% from heart disease. On the other hand, males have a 22% lower risk.
  • Stroke mortality is 42% lower in women and 35% lower in males.

Some More Possible Health Benefits of Green Tea:

  • Cardiovascular: Green tea helps in lowering the blood pressure in hypertension and protects against the formation of clots. Green tea also benefits in lowering bad cholesterol.
  • Tooth decay: Antioxidant “catechin” in tea can destroy bacteria and viruses that cause throat infections, dental caries, and other dental conditions.
  • Anti-aging: Green tea helps in anti-aging and wrinkles because of its anti-inflammatory and antioxidant properties
  • Diabetes: Green tea may help reduce the risk of type-2 diabetes.
  • Brain function: The caffeine in green tea increases alertness, amino acid L-theanine works synergistically with caffeine to improve brain function. It also protects the brain from aging and lowers the risk of dementia.
  • Bad breath: The catechins in green tea inhibit the growth of bacteria in the mouth and hence help in reducing bad breath.
  • Cancers: The antioxidants can help oxidative damage and thus reduces the risk of several cancers.
  • Psoriasis: Green tea can be helpful in an inflammatory disorder called Psoriasis which is characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells.
  • Weight loss: Increased metabolism by green tea may help losing weight.
  • Stress and depression: Amino acid theanine found in green tea provides a relaxing and tranquilizing effect.
  • Eyes: Cold green tea bags are also used to decrease puffiness under the eyes, as a compress for tired eyes.
  • Acne: Drinking green tea and applying a cold compress of green tea may help reduce the inflammation of acne.

Several potential health benefits of green tea exist. For instance, it could benefit type 2 diabetes, skin irritation, and weight control. Several studies have also linked green tea consumption to improved cardiovascular health.

Green tea has one of the highest antioxidant levels of any beverage. By definition, it contains fewer calories and less caffeine than black tea and coffee.

Consider including green tea in your regular diet to help you feel better, lose weight, and lower your risk of chronic diseases.
