10 Amazing Health Benefits of Green Tea
The health benefits of green tea, which is a panacea such as preventing diseases, anti-aging and losing weight, are in this article.
Many studies conducted in the Western world in recent years have shown that tea strengthens memory, increases mental capacity, especially in adults, and is a source of vitality and health. However, it is green tea used in the Far East, which has much stronger protective effects than the black tea we drink.
Green tea is obtained by exposing the tea plant to high heat after harvesting. Exposing the tea plant to high heat, you inactivate an enzyme called polyphenol oxidase, which causes it to turn black.
Epidemiological studies conducted in the Far East, especially in China, show that people who consume large amounts of green tea have a very low risk of developing cardiovascular diseases, many types of cancer, oral and gingival diseases, obesity and type II diabetes. It has been observed that diseases such as Parkinson’s and Alzheimer’s diseases have also decreased. These results have aroused great interest in the western world and have led to intense research into the phytochemicals found in green tea.
Green tea contains natural compounds called catechins. These catechins make up 40% of green tea. These compounds have very strong health protective effects. However, one of them is the strongest and is called EGCG (Epigallocatechin Gallate). This compound is a miracle of nature.
In addition to catechins, green tea also contains very little amino acids, carbohydrates, some fatty acids, vitamins B, C, E, caffeine and theophylline. It also has trace elements such as calcium, magnesium, chromium, manganese, iron, copper, zinc, molybdenum, selenium, sodium, potassium and so on. However, the amount of these substances is quite low.
Protective effects of green tea
Green tea, which has been used in traditional medicine in China for 5000 years, has effects that strengthen circulation and facilitate to induce urination. In Traditional Chinese Medicine, it has been used for thousands of years to relieve various body aches, improve digestion, relieve depression symptoms, detox your body and increase energy. Caffeine in green tea is found in many pain killers today. The theophylline in tea has been used for many years in modern medicine for shortness of breath such as asthma.
Medicine is for one disease, green tea is for every disease

In clinical studies with green tea, it has been seen that it prevents the damage caused by free oxygen radicals in cells. Green tea catechins, especially EGCG, have very strong antioxidant activities. EGCG has antioxidant activity that removes free oxygen radicals that degenerate body cells. Free oxygen radicals degenerate body cells, disrupt the vascular system, cause arteriosclerosis, destroy the nervous system, cause dementia, cause malignant tumor development such as cancer by disrupting the genetic code of the cell. EGCG eliminates these harmful effects of free oxygen radicals.
1- Green tea against cancer
Perhaps the most important feature of EGCG, the strongest ingredient in green tea, is its anti-cancer effect. Studies with green tea or pure EGCG have shown that these compounds have protective effects against especially skin cancer, intestine, lung, oral cavity, esophagus, stomach, liver, pancreas, breast, kidney, prostate, bladder cancers. Today, it is clearly known that it has protective effects especially against bowel, skin, lung, prostate and breast cancer.
2- Green tea against heart disease
It has been reported that cardiovascular diseases are less common in societies that consume green tea. Studies with green tea or EGCG have shown that this active ingredient lowers blood cholesterol, reduces the storage of bad cholesterol (LDL cholesterol) into the vein.
It has been also determined that green tea increases the potential of vascular dilatation, protects against high blood pressure, and reduces death due to heart attacks and heart diseases. However, it should be kept in mind that green tea is not a medicine, it is basically a health protector rather than the treatment of a disease like drugs, and it can be used as an adjunct to the treatment of cardiovascular diseases. In particular, the amount of caffeine in green tea should be known. Caffeine intake of more than 400 mg per day may cause a risk for heart diseases. Caffeine can cause serious arrhythmias. In such cases, the daily caffeine intake limit of 300mg should never be exceeded. This is roughly equivalent to 9 cups.
3- Green tea for oral care
Green tea catechins and especially EGCG prevent tooth decay, relieve gingivitis, eliminate bad breath. They also resist degenerative cell proliferation that occurs in the mouth and tongue and leads to cancer, and prevents the formation of dental plaques. Therefore, stabilized EGCG is used in modern toothpastes, mouthwashes and mouth sprays. Since EGCG is very easily degraded by water, it is used in mouthwash, toothpaste or gum spray.
4- Green tea for hair and skin care
In this section we handle green tea benefits for skin and hair. Green tea is an indispensable food for skin and hair health. It prevents and delays photo-aging on the skin, especially caused by sun rays. It also prevents the formation of skin cancer due to ultraviolet.
Green tea also has a special importance for hair. Hair loss may be caused by the high activity of an enzyme called 5α reductase in the scalp. Green tea catechins, and especially EGCG suppress this enzyme. They prevent hair follicle degeneration that leads to hair loss and baldness. They prolong the life of hair-producing cells in the hair follicle. That’s why green tea and EGCG are used all over the world in natural tablets to prevent hair loss. Contrary to these effects, green tea has the effects of reducing facial hair growth. Green tea and EGCG prevent acne and they are now used in modern medicine to treat acne.
5- Green tea for weight loss
One of the strongest benefits of green tea is its weight loss effect. Studies conducted in both Europe and America have shown that EGCG, the active component of green tea, accelerates body metabolism, reduces the absorption of fat and sugar from the intestines, resists the formation of new fat cells, and increases the burning of fat stored under the skin.
Green tea also has strong health protective effects in Metabolic Syndrome. Metabolic Syndrome manifests itself with obesity or fat around the abdomen and waist and it is defined as the epidemic of the age. In metabolic syndrome, intra-abdominal fat, and especially fat in the organs in the abdomen, has much more disease-causing features than obesity, which we all know in general. In metabolic syndrome, this intra-abdominal fat causes type II diabetes, cardiovascular diseases, rapid deterioration in memory. It also disrupt learning and perception abilities.
6- Green tea against cholesterol and atherosclerosis
In a clinical study conducted at the end of 2009 by Harvard and Florida Medical School; Researchers studied adults who took green tea capsules containing approximately 90 mg of EGCG (2 per day) for 3 weeks. Researchers concluded that it alleviated high blood pressure, LDL cholesterol level, free radical damage and chronic inflammatory reaction, which are risk parameters leading to cardiovascular diseases.
In a similar study, another group of researchers from the University of Parana showed that green tea extract reduced total cholesterol and LDL-cholesterol, known as bad cholesterol, in the blood. The individuals in this study were overweight. All these results show that green tea can be used to prevent obesity or obesity-related diseases such as metabolic syndrome.
7- Green tea for anti aging
Green tea catechins also have anti-inflammatory properties. Inflammation is not just inflammation with microbes. Inflammatory reactions that progress insidiously in the body cause many chronic diseases, especially cancer, neurological disorders such as Parkinson’s disease and Alzheimer’s disease.
Green tea prevents chronic degenerative diseases. Studies revealed that green tea catechins prevent excessive increase in many immune signals such as IL-6, IL-8, NFkβ, iNOS, COX, which play a role in the emergence of inflammatory reactions.
8- Green tea for mental activity
Green tea has energy-boosting activity. Beyond that, it has been found to increase mental capacity by affecting the neural activation of the brain and acting on substances called neurotransmitters that play a role in inter neural communication.
The researchers of the world-famous ILLINOIS University in the USA emphasize that it protects against neurodegenerative diseases such as Alzheimer’s and Parkinson’s, which occur with free oxygen radicals that cause degeneration of brain cells, inflammatory reactions and nerve cell death. These researchers say that green tea is very effective in both strengthening mental activity and protecting from neurodegenerative diseases associated with aging.
9- Green tea against germs
Green tea has the ability to strengthen the immune system. It is also antiviral and antibacterial. Especially in recent years, it has been determined that it is effective against aureus type staphylococci that cause fatal infections, HIV virus that causes AIDS and even against type A influenza virus and against rotavirus that causes severe diarrhea in children. Recent studies show that it is also effective against Helicobacterpylopi bacteria, which causes stomach ulcers.
10- Green tea for bones
In a detailed report published in 2009 led by the University of Texas in the USA, it was reported that green tea catechins protect against osteoporosis, increase bone formation and prevent bone resorption. With all these bone protective effects, it was revealed green tea can reduce the risk of bone fracture, which is especially common in the postmenopausal period
As a result, green tea tablets or beverages have many benefits that help strengthen the body, increase mental activity, lose weight and prevent the formation of many chronic diseases.
