Introduction of Dr. Tadashi Mitsuo, Director of Mitsuo Clinic
About 8 effects
1 Does it have an antioxidant effect? Green tea contains a lot of polyphenols with antioxidant properties such as flavonoids and catechins. It is widely known that its function is important for the repair of cell membranes damaged by oxidative stress. The most important component is a polyphenol called epigallocatechin gallate (EGCG). There are many studies on various health effects such as prevention of lifestyle-related diseases by EGCG.
2 What is maintenance of brain function? Green tea contains caffeine, although not as much as coffee. Moderate amounts of caffeine increase dopamine and norepinephrine , which help you focus. They are essential for brain cells.
L-theanine, a type of amino acid contained in green tea, also has an important function of increasing GABA, which has a sedative effect.
3 Does it have a fat burning effect? There are studies that show that green tea can increase energy consumption by as much as 4% , and research reports that it enhances fat burning effects . These effects may be due to the caffeine contained in green tea, but tea drinking after meals can be expected to prevent fat accumulation .
- 4 Can cancer be prevented?
Numerous research reports have shown that green tea has anticancer effects by protecting the body from oxidative stress. It has been shown to reduce the incidence of breast cancer, prostate cancer, and colon cancer.
5 What is infection control? The catechins contained in green tea have antibacterial properties . Drinking green tea after meals is known to eliminate tooth decay bacteria and prevent the occurrence of tooth decay and periodontal disease. It has also been reported to be effective in preventing bad breath and upper respiratory tract infections.
There are also research results that it has a bactericidal effect against coronavirus.
- 6 Will it help prevent diabetes?
Green tea has been reported to improve insulin sensitivity. One study reported that regular consumption of green tea reduced the risk of developing type 2 diabetes by 42%. A study of about 280,000 people found that green tea drinkers were 18% less likely to develop diabetes.
7 Can heart disease be prevented?
The antioxidant properties of green tea are extremely effective in heart protection . Not only does it reduce oxidative stress, but it also improves the lipid balance in the blood, so it is said that people who drink a lot of green tea have a 31% lower risk of cardiovascular disease.
8 Healthy longevity effect! A study of approximately 40,000 Japanese who drink 5 or more cups of green tea a day found a reduction in mortality (men: 12%, women: 23%) and a reduction in deaths from heart disease (men: 22%, females: 22%) and cerebrovascular disease mortality (males: 35%, females: 42%).
