10 Evidence-Based Benefits Of Green Tea

High quantities of antioxidants in green tea have the potential to improve several aspects of health, including mental clarity, cancer prevention, and weight control. While every type of tea contains some antioxidants, green tea has a higher nutritional profile due to the process of production. In contrast to other types of tea, green tea is made from mostly unprocessed, unfermented, unoxidized leaves, and it may have higher levels of antioxidants and other health-promoting minerals.

Since ancient times, green tea has been used in Chinese and Indian medicine to promote both physical and mental health. This is due to its numerous health benefits. These outstanding assertions are being increasingly investigated through experimental science.

Some major anticancer properties of green tea have been suggested by a 2019 evaluation of its effects.

Over the period of 30 years, scientists and human investigations discovered proof of beneficial benefits in both animal and human cells. This included fewer cases of cancer in the general population, decreased cancer recurrence rates in patients with stage 1 and 2 cancer, and secondary cancer protection when used in conjunction with anticancer medications.

Additionally, it was discovered that chronic green tea use over a ten-year period could cause cancer to develop up to 8 years later than in people who drank less of it.

• Encourages Heart Health

According to a review of epidemiological, experimental, and clinical studies published in 2019, drinking tea may reduce your chance of developing cardiovascular disease.

Consuming tea components were found to have positive health impacts, including protection against the onset of cardiovascular disease. A lower frequency of cardiovascular events and a lower risk of dying from cardiovascular disease were also associated with regular green tea use.

• Key Source Of Antioxidants 

A key component of green tea is a collection of substances known as polyphenols, a potent class of antioxidants with anti-inflammatory and free radical-neutralizing characteristics that have been shown to enhance health. Oxidative stress can result from free radical levels that are out of balance. Cell damage may result if this is damaging over an extended period of time.

Since green tea has a very high concentration of these antioxidant polyphenol chemicals, there may be considerable health effects from consuming it. The health advantages of green tea and its constituents are supported by a 2021 evaluation that examined the clinical uses of tea polyphenols in both animal and human trials. 

• Promoting Skin Health

An analysis from 2019 demonstrates how green tea benefits skin health. With proof of the repair of skin damage from UV radiation and the prevention of related skin malignancies, researchers were able to show the potential effects of topical tea polyphenols.

Similar data supporting the use of topical and swallowed green tea therapies as a prophylactic measure against skin aging and skin cancer was discovered in another assessment of human clinical studies. Research has also demonstrated the effectiveness of medicines developed from green tea in the treatment of persistent, infectious, inflammatory, and hair diseases.

• Enhancing Mental And Emotional Health

According to a thorough database assessment, green tea has favorable effects on:

1. Fear of memory and focus
2. Generalized brain activity
3. Anxiety

• Prevents Type 2 Diabetes 

Green tea components have been shown to have some beneficial effects on diabetes in animals.

One overview of research on both humans and animals discusses the possible connection between drinking green tea and the management of type 2 diabetes. The green tea component EGCG had strong intestinal effects and was also able to decrease intestinal glucose uptake, according to the results of green tea treatment in humans.

• Aiding In Weight Management

Since traditional medicine has long touted green tea's ability to reduce weight, there has been a heightened interest in how it affects obesity and weight loss. In a review of clinical studies conducted on both humans and animals published in 2015, researchers noted that green tea might be helpful for the treatment and prevention of obesity.

The rate of weight reduction was somewhat higher in the group using green tea supplements, but the difference was not statistically significant, according to the researchers.

• Increasing Longevity

Green tea use has been linked to longer lifespans, which is consistent with research suggesting the beverage may have a number of health advantages.

One study analyzed two studies that followed up over a 14-year period with a total of over 115,000 individuals ranging in age from middle age to old age. It was discovered that drinking green tea could lower everyone's risk of dying from any cause, but it was especially true for individuals who had never smoked.

• Improved intestinal health

Research has shown that green tea has other health advantages, including the ability to enhance gut health.

According to a review of studies, green tea's high levels of polyphenols may both inhibit the growth of some harmful bacteria and encourage the growth of advantageous species of gut flora.

Summary

There is a wealth of research supporting the possible health advantages of green tea. Heart health, cancer prevention, longer life, better skin and intestinal health, weight loss, and improved mental function are examples of positive health effects.

Green tea gives a potent dosage of antioxidants and is low in caffeine compared to other caffeinated beverages, although further research is required to conclusively corroborate some of these discoveries, particularly to determine efficacy and consumption quantities.
