Green tea is highly regarded, and in many circles it has earned the reputation of being the ‘healthiest beverage in the world.’ Full of nutrients and antioxidants, green tea has a powerful impact on the body and mind when consumed.
Here are 10 health benefits of green tea that have been confirmed in human research studies:
Green tea contains natural compounds called Polyphenols, which have antioxidising properties. This means that these substances can reduce the formation of free radicals (reactive chemical compounds that accelerate aging, and cause various types of disease) in the body, protecting cells and molecules from damage.
2. Brain Function
The caffeine concentration in green tea is less than that of coffee (does not cause the jittery feeling), but enough to produce a beneficial effect to our brains. The caffeine blocks an inhibitory neurotransmitter called Adenosine that exists in the brain. This way, it actually increases the firing of neurons and the concentration of neurotransmitters. In short, we get smarter.
3. Fat Burning
In human controlled trials, Green tea has been shown to increase fat burning and boost the metabolic rate. Also, the caffeine in green tea has been shown to improve physical performance by pushing fatty acids away from the fat tissues and converting them into a source of energy
Cancer is caused by uncontrolled growth of cells. The antioxidants that exist in green tea protect the body against oxidative damage which leads to the development of different types cancer. Specifically colorectal, breast and prostate cancer.
5. Alzheimer’s and Parkinson’s
Multiple studies show that bioactive compounds (compounds that have an effect on living tissue) in green tea called catechin can have various protective effects on neurons. This may reduce the risk of both Alzheimer’s and Parkinson’s, the two most common neurodegenerative disorders.
6. Kill bacteria
Streptococcus mutans is the primary harmful bacteria in the mouth. It causes plaque formation and is a leading contributor to cavities and tooth decay.
Studies show that the catechins in green tea can inhibit the growth of streptococcus mutans. Green tea consumption is associated with improved dental health and reduced bad breath!
7. Type II Diabetes
Studies show that green tea can improve insulin sensitivity and reduce blood sugar levels , and that those who drank the most green tea had a significantly lower risk of developing type II diabetes.
8. Cardiovascular disease
Green tea dramatically boosts the antioxidant capability of blood, which protects the LDL cholesterol particles from oxidation, which is one part of the pathway towards heart disease. Green tea drinkers have up to a 31% lower risk of cardiovascular disease (heart disease, stroke).
9. Lower risk of obesity
Given that green tea can boost the metabolic rate in the short term, it therefore makes sense that it could aid in weight loss, particularly body fat. It is specifically effective at reducing the abdominal fat, which is dangerous at high levels.
10. Improve Life expectancy
In a study of 40,530 Japanese adults, those who drank the most green tea (5 or more cups per day) were significantly less likely to die during an 11 year period.
