Benefits of Green Tea- An Ultimate Guide to Unveil the Nature’s Love
Green tea is considered one of the best beverages in the world due to its health benefits. Initially, it was used as a medicine in India and China. Now it is being used in America, Europe and all across the world due to its miraculous health benefits. In the world, 2.5 million tons of tea leaves are produced annually, and 20% of it is green tea.
A lot of people get confused about the source of green tea and black tea. The fact is that the same plant Camellia sinensis produce both of these drinks. These differ in post-production processing. For green tea production, camellia leaves are readily steamed. Steam inhibits fermentation and denatures enzymes responsible for the breakdown of color pigment. In contrast, fermented leaves result in the production of oolong tea and black tea.
Green tea leaves mainly contain protein, amino acid, carbohydrates, fiber, polyphenol, caffeine and pigments. Healthy bioactive component polyphenol accounts for 30% of dry weight and caffeine 0.4-10% dry weight.
Health benefits of green tea
Green tea has many renowned health benefits confirmed by researchers. So, let’s dive in to learn some of these exciting benefits of green tea. Most importantly how they can help us in our every day life:

A study suggests that people who take green tea with exercise results in 17% increased fat burn compared to those who don’t.
- Antioxidant properties
Several endogenous and exogenous oxidants produce reactive free radicals in the living body. These free radicals react with DNA, lipids and protein etc. to cause cellular and tissue damage. Imbalance in the antioxidant and reactive oxygen leads to oxidative stress. Green tea contains natural antioxidant catechin epigallocatechin gallate (EGCG) that balances the body’s free radicals. It reduces the risk of tissue damage and oxidative stress.
- Green tea and cardiovascular diseases
Cardiovascular diseases are responsible for most of the deaths in the World. The leading causes behind it are the high blood cholesterol level and high blood pressure. The polyphenol catechin present in green tea decreases the level of bad cholesterol in the blood and lowers the blood pressure. Furthermore, it decreases stroke risk. Researcher indicates that daily consumption of green tea results in a 5% lower risk of cardiovascular mortality.
- Alleviate the risk of cancer
The unplanned and uncontrolled cell growth in the living body is cancer. Green tea protects against several environmental cancer causes. Oxidative stress leads to inflammation which is a possible risk factor of cancer. The antioxidant action of polyphenol catechin antagonizes the oxidative stress and in turn, decreases the cancer risk. It also decreases tumor growth. Studies indicate women who consume green tea have a 20-30% lower risk of developing breast cancer. Furthermore, the people who drink daily a cup of this tea have 42% less possibility of developing colorectal cancer. It also minimizes the risk of oral, prostate, lung, stomach and pancreas cancer.
- Green tea and type 2 diabetes
The high level of glucose in the body leads to diabetes. The major causes of diabetes are insulin resistance or the inability of the body to produce insulin on a genetic basis. Type 2 diabetes is one of the deadliest diseases all over the world. Moreover, it leads to other complications such as heart problems, slow healing, obesity, neuropathy etc. Green tea can improve insulin sensitivity, lower fasting blood sugar level and reduce HbA1c (a sugar-binding hemoglobin) level in the blood. A study shows 18% lower risk of diabetes in tea drinkers.
- Improve brain function and memory issue
Our brain is the master organ of the body, which controls the whole body’s function, human personality and behavior. The key ingredients in the green tea caffeine, L-theanine, and catechins have noteworthy effects on brain-boosting. Caffeine increases the nerve impulse conduction. Caffeine, along with amino acid L-theanine, improves working memory, learning power, mood, activity and nerve responses. One of the active ingredients of tea catechin slows down the ageing process of the brain. The ageing process of the brain leads to Alzheimer’s, Parkinson’s and memory loss.
- Anti-ageing and Skincare
Green tea has anti-ageing effects due to its antioxidant and anti-inflammatory activity. Besides, it protects the skin from harmful ultraviolet rays and sunburn. It slows down the wrinkles formation. Teabags of green tea used to treat dark circles and sunburns. It also used to treat the red, dry patches of skin caused by inflammation and uncontrolled cell growth.

Antibacterial action of tea kills the mouth bacteria that cause bad breathing, tooth decay and tooth cavities. It is also used to treat influenza virus in its earlier stages.
- Green tea and bone density
Green tea improves bone density and ultimately protects the bones from fracture. The antioxidant properties inhibit the leaching of important minerals from bones. Tea catechin enhances the absorption of important minerals that strengthen our skeleton. Furthermore, anti-inflammatory properties also reduce the risk of bone disorder like arthritis.
- Increase life span
Studies indicate people who take green tea regularly tend to live longer. The possibility of a longer life span is due to the reduced risk of developing cardiovascular diseases, diabetes, and bone problems etc. Moreover, the people who take green tea regularly, tend to have a younger biological age of the body cells. Whereas the ratio is lower for a person who doesn’t takes green tea.
