It is known that green tea was used 5,000 years ago in Southern China and different beverages were prepared from green tea. Traditional Chinese medicine, BC. Healthy people are recommended to drink green tea to prevent stress in his books written between 1000-200. In short, this information shows that green tea has been known for thousands of years and has been used as a healing agent. On the other hand, recent studies have revealed that antioxidants play an important role in maintaining health.
For this reason, it is increasingly common to take antioxidants by drinking tea. Bag herbal teas prepared from plant parts carrying different antioxidant substances are available in the market. The most important of these is green tea. Therefore, green tea consumption has increased significantly in our country in recent years.
How is green tea obtained?
Green tea is the unfermented leaves of the tea plant. 2-3 leaves above and below the plant are collected and dried. Its chemical structure is similar to black tea, but polyphenols with antioxidant effect are more in green tea. Therefore, it is mostly used for this purpose. Drinking 3-4 cups of green tea a day is enough to get the right amount of antioxidants.
Important substances transported by green tea
Green tea catechins, flavonols and different polyphenol structures, as well as an amino acid called caffeine and theanine. carries matter. The beneficial use of green tea for health is due to the common effects of these substances. Green tea contains 2-4% caffeine, 1-2% theanine and 25% catechins that provide antioxidant effects.
How should green tea be prepared?
Most of the catechins pass into the water in the first 5 minutes of brewing. If lemons are found in the environment, the rate of transition to water increases. Therefore, it is kept for about 5 minutes after adding 70-80 degrees of hot water to the green tea placed in the glass and putting 1 thin slice of lemon. When the bag is removed at the end of this period, sufficient antioxidant density is provided in the liquid in the glass.
Health and theanine
In recent years, many studies have been conducted on experimental animals and humans on theanine. Let’s talk about some of them: Studies in rats have been shown to accelerate learning and increase recall. Again, studies in rats showed that those with high blood pressure had a significant reduction in blood pressure and there was no change in those with normal blood pressure. It is a result obtained in studies conducted with experiments that caffeine reduces the blood pressure increasing effect.
In a study conducted on humans in Japan, subjects were given 50-200 mg of theanine and found that theanine increased the frequency of alpha waves in the brain, compared to subjects not used. The increase in the frequency of alpha waves is very important as it creates relaxation and relaxation without causing drowsiness in the person. In recent studies based on this information, theanine has been shown to have a corrective effect in people with high anxiety disorders (a persistent, excessive, and inappropriate anxiety state).
Another important information that emerged as a result of the research is that serum, liver and brain reach the highest level 1 hour after taking theanine, this level decreases rapidly in serum and liver, but begins to decrease in the brain 5 hours after ingestion. This information is extremely important as it explains the use of green tea as a relaxing agent in traditional Chinese medicine. In fact, this information is enough to explain the importance of the trainee.
To state that most of the other studies on green tea are epidemic studies in Far Eastern countries where green tea is consumed continuously.
Due to its antioxidant effect, it has been found to provide a protective effect against cancers such as colon, breast, small cell lung cancer and prostate cancer. ”
He said that by drinking 4-5 cups of green tea a day, a good and inexpensive antioxidant effect can be achieved, as well as positive effects on the cardiovascular system. Sezik highlights the positive effects of the intern on learning and recall as well as anxiety-relieving effects.
