People have admired the health benefits of green tea for centuries. Studies suggest that drinking green tea may positively affect skin health, aid in weight loss, and reduce the risk of cardiovascular disease.
All teas except herbal teas are made from the dried leaves of the Camellia sinensis bush. The degree of oxidation of the leaves controls the type of tea.
Green tea is made from unoxidized leaves and is one of the minor processed types of tea. For this reason, it contains the highest amount of beneficial antioxidants and polyphenols.

Health Benefits Of Green Tea
People use green tea in traditional Chinese and Indian medicine to control bleeding and heal wounds, aid digestion, improve heart and mental health, and regulate body temperature.
Studies suggest that green tea may benefit weight loss, liver disease, type 2 diabetes, Alzheimer’s disease, and more.
However, it is essential to note that more evidence is need before scientists can definitively prove these potential health benefits.
A review of several studies found that the catechins in it and caffeine may increase energy metabolism, which may lead to weight loss.
Another meta-analysis of several different tea polyphenol-induced weight loss mechanisms suggested that catechins and caffeine produce synergistic weight loss effects rather than being the result of caffeine alone.
However, the effects of it consumption on weight loss are unlikely to be of clinical significance. Most studies that have shown small changes in metabolism have used it extracts with extremely high concentrations of catechins.
Inflammatory Skin Diseases
Green tea has anti-inflammatory properties. A trust source reviewing clinical, cell, and also, human-animal studies found that green tea and its key ingredient, epigallocatechin-3-gallate (EGCG), have been shown to have anti-inflammatory effects.
A 2019 review by Trusted Source on tea extract in cosmetics confirmed this. Researchers found that solutions containing tea extracts promoted anti-inflammatory responses when applied topically. They also found that skin microcirculation improved in the affected areas.
A 2006 study from Trusted Source suggested that green tea consumption was associated with reduced mortality from cardiovascular disease.
The study followed more than 40,000 Japanese participants between the ages of 40 and 79 for 11 years starting in 1994. It found that participants who drank at least five cups of green tea a day had a lower risk of dying from cardiovascular disease.
A 2011 review found that drinking green tea, either in drink or capsule form, was associate with a significant but modest reduction in total low-density lipoprotein cholesterol.
The Risk Of Stroke
Regular consumption of it or coffee appears to be associate with a lower risk of stroke.
Since the American Heart Association (AHA) study found that including it in a person’s daily diet may be associate with a small but positive change in stroke risk.
Type 2 Diabetes
Studies on the relationship between and diabetes are conflicting.
Some have suggested a lower risk of type 2 diabetes in people who drink it than those who don’t. A review of 17 randomized controlled trials from a trusted source found a correlation between it consumption and lower fasting glucose and insulin levels.
Types Of Green Tea
Green Tea Is Available In Many Types And Forms, Including:
- bottled and sweetened with sugar or an artificial sweetener
