Health Benefits of Green Tea

Besides being a hydrating beverage, green tea contains a range of healthy compounds that make it fit for the final drink. These healthy compounds help in maintaining healthy body weight and lowering risk due to many life-threatening diseases. 

Green Tea is rich in polyphenols,  the natural compounds that reduce inflammation and help fighting cancer.

Green tea is also a rich source of catechins the natural antioxidants. Catechins reduce the formation of free radicals and prevent cell and molecules damage. Catechin Epigallocatechin-3-gallate (EGCG) is the main compound that gives green tea all its medicinal advantages. Studies indicate that catechins in green tea can inhibit the growth of oral bacteria in the lab, but no evidence shows that drinking green tea has similar effects. However, there’s some evidence that green tea may reduce bad breath.

Green tea can also contain fluoride which may be harmful to human beings. Therefore, sometimes the benefits still outweigh any risk.

Green tea keeps a person alert and may boost brain function also.

Caffeine though is in small amounts in green tea but is the active ingredient of green tea and is a well-known stimulant. Caffeine in green tea is sufficient to block Adenosine, an inhibitory neurotransmitter. Green tea thus increases the concentration of neurotransmitters and improves their functioning the same ways as dopamine and norepinephrine works. Researches have consistently shown the positive impact of caffeine on mood, vigilance, reaction time, and memory.

Green tea also contains amino acid L-theanine, which reduces anxiety by increasing the activity of the inhibitory neurotransmitter GABA. Studies show that both caffeine and L-theanine synergize to improve brain functioning. People, therefore, feel more energetic and more productive when they drink green tea, compared with coffee. Green tea may also protect the brain from the ill effects of aging.

Studies have shown that catechin compounds in green tea protects neurons in test tubes and also in animal models, possibly lowering the risk of dementia.

Green tea helps burning fats and Weight Loss

Researchers have suggested that green tea can increase fat burning, boost metabolic rate, and can help in Weight Management. Whereas in few studies taking green tea extract has improved fat burning with different rates among individuals but in some cases, it doesn’t show any increase in metabolism. Based on results it can be said that the net effect of green tea on metabolism and fat burning depends on the individual. Caffeine also mobilizes fatty acids from fatty tissues and helps in burning fats especially in the abdominal area

Antioxidants in Green Tea may lower the risk of some cancers

Cancer, caused by uncontrolled cells growth, is a leading cause of untimely and preventable deaths throughout the world. Oxidative damage can cause chronic inflammation leading to chronic diseases which include cancers also. Antioxidants in green tea can help protect against oxidative damage.

Studies have revealed a lower incidence of breast cancer among women and also reduce the risk of prostate cancer. Drinking green tea has also reduced the risk of colorectal cancer. However, more research needs to be done to prove the facts, a higher level of quality research is needed to confirm this.

Green tea may help prevent type 2 Diabetes

Studies show that green tea may improve insulin sensitivity and reduce blood sugar levels. A study on Japanese individuals found people drinking green tea regularly had a 42% lower risk of type 2 diabetes.

Green tea may help prevent cardiovascular disease

Green tea also reduces the chances of cardiovascular diseases, including heart disease and stroke. It increases antioxidants in the blood that reduces the oxidation of LDL (bad cholesterol). A recent study indicates people drinking green tea have a 31% lower risk of dying from a cardiovascular disease

In one study on Japanese adults over 11 years time period, it was found that those who drank 5 or more cups per day of green tea were significantly less likely to die during the study period. Another study on old Japanese individuals found that all those who drank green tea regularly have 76% less likely to die during the 6-year study period.
