In China, tea drinking has become a culture and a part of everyday life. Whether it's the first glass of water in the morning or a moment of relaxation between work, tea seems to be indispensable.
For friends over 35 years old, health gradually climbs to the top of the agenda as they get older, and drinking tea has become a choice for health. But, you know what? Drinking tea is good, but it's also exquisite. Under normal circumstances, how much tea is the most appropriate amount for a person to drink in a day?
1. Tea nutrients
Tea has been known as "liquid gold" since ancient times, not only because of its taste, but also because of its nutritional value. Delve deeper into tea and you'll discover the mysteries it contains. 93% to 96.5% of tea is organic matter, these include amino acids, proteins, carbohydrates, etc., which our body needs.
Among them, the content of leaf protein is as high as 20% to 30%, and the free amino acids are also 1.5% to 4%, and there are many types, as many as 20 kinds. These nutrients are essential for maintaining the normal functioning of our body.
When it comes to inorganics, tea is not absent, with a content of about 3.5% to 7%, covering 27 mineral elements such as calcium, iron, magnesium, zinc, and manganese.
These are all essential elements for our body's metabolism. The richness of these nutrients makes drinking tea not only a cultural enjoyment, but also a healthy lifestyle.
2. Appropriate daily tea intake
The total amount of water an adult needs is between 2,000 and 2,500 ml per day.
Of these, food can provide us with 600 to 800 ml of water, and the rest needs to be replenished by drinking water or tea. At this time, tea can show its talents, not only to quench thirst, but also because of the existence of nutrients, it plays a role in health care.
However, drinking tea should not be excessive. Excessive amounts of tea may adversely affect the body. Generally speaking, about 1500 ml of tea per day is enough for our body, which is equivalent to about 5 cups of 300 ml of tea.
Of course, this amount is not fixed, everyone's physique is different, the amount of activity is different, and the habit of drinking tea is also different, which will affect everyone's appropriate tea intake. Therefore, finding the right amount for yourself is the most important.
3. Tea brewing skills and foaming resistance
The brewing technique of tea has a direct impact on the taste and nutrient release of tea. Taking green tea as an example, the optimal brewing temperature should be controlled at about 80°C, which can avoid destroying the vitamin C and amino acids in the tea, and at the same time can fully release the tea polyphenols and aroma.
Green tea has relatively low foam resistance, and usually after 3 to 4 brews, its taste and nutritional value will be significantly reduced. For partially fermented teas such as oolong tea, due to its high temperature treatment, it is more resistant to brewing, and can be brewed many times, and different flavor levels can be tasted each time it is brewed.
According to the "Chinese Tea Standard Brewing Method" and a number of tea studies, the appropriate brewing time and water temperature can maximize the stimulation of beneficial substances in tea.
For example, when black tea is brewed at a water temperature of 90°C, it is able to release more theaflavins and thearubigins, which have positive effects on human health, such as promoting digestion and lowering blood lipids. Therefore, mastering the correct brewing method can not only enhance the tea drinking experience, but also make better use of the nutrients in the tea.
Fourth, the impact of tea drinking habits on health
The habit of drinking tea, especially the concentration and time of tea, has a non-negligible impact on health. Weak tea is suitable for regular consumption because it does not put too much burden on the stomach and intestines, and can also provide certain antioxidants and other nutrients. Although strong tea is highly nutritious, too strong tea may cause stomach upset and even affect iron absorption.
In addition, drinking tea on an empty stomach may stimulate gastric acid secretion and aggravate stomach discomfort, while drinking tea before bed may affect sleep due to the stimulant effect of caffeine.
Individual physical differences are also an important factor in determining the appropriate amount of tea to drink. For example, for people with different physiques, such as "hot constitution" and "cold constitution", the choice of tea type and drinking amount should also be different.
The Dietary Guidelines for Chinese Residents suggest that for the average adult, drinking tea in moderation can bring benefits to the body, but for special groups, such as pregnant women, children and people with specific diseases, the amount of tea should be more cautious.
From a medical point of view, moderate tea consumption has a positive effect on the prevention of chronic diseases such as cardiovascular disease and type 2 diabetes.
According to a study published in the American Journal of Clinical Nutrition, moderate tea consumption is associated with a reduced risk of cardiovascular disease. However, excessive tea consumption may cause adverse effects such as heart palpitations, insomnia, and other symptoms due to excessive caffeine intake.
5. Tea and health: the scientific basis for rational tea drinking
Tea polyphenols are the main active ingredient in tea and have strong antioxidant properties, which are able to scavenge free radicals in the body and reduce the risk of cell damage and chronic diseases.
In a study published in the European Journal of Preventing Cardiovascular Disease, researchers found that people who regularly consumed green tea had a significantly lower rate of heart attacks than those who did not drink it or drank it less.
Although the caffeine in tea is a stimulant, moderate intake can also increase metabolic rate, help burn fat, and help control weight.
However, caffeine intake should be kept within a safe range, as excessive amounts may cause uncomfortable symptoms such as anxiety and rapid heartbeat.
Therefore, for friends who want to drink tea to help lose weight, it is very important to choose low-caffeine tea and control the amount of daily drinking.
6. Tea and Culture: The Cultural Significance of Tea Drinking Habits
Tea is not only a drink, but also a cultural embodiment. In China, tea culture has a long history, and the tea ceremony shows people's pursuit of a better life and inner peace.
In daily life, a cup of tea is often accompanied by a gathering of friends or a moment of solitary reflection, which not only nourishes the body, but also enriches the mind. Tea, as a carrier, carries people's yearning for a harmonious and quiet life.
At the tea table, people share their stories, and friendship and wisdom are quietly passed on between the fragrance of tea. This cultural enjoyment goes far beyond the nutritional value of tea itself. Therefore, drinking tea reasonably is not only for physical health, but also for spiritual pleasure and cultural experience.
7. Tea and life: how to integrate tea drinking into daily life
Integrating tea drinking into daily life is one way to improve the quality of life. In between busy work, a cup of tea can relax and improve work efficiency.
At the end of a family meal, a pot of aromatic tea can help to eliminate food and enhance communication between family members. For those who pursue a healthy life, learning the art of tea, understanding the types of tea and brewing methods can not only increase the joy of life, but also pay attention to healthy details in their daily diet.
When choosing a tea, one should take into account one's taste preferences and physical condition. For example, people with a cold stomach should choose warm black or dark tea, while people who need to clear heat and detoxify are more suitable to drink green tea.
In addition, the change of seasons is also a factor in the choice of tea, green tea can be drunk in summer to clear the heat, and in winter it is advisable to drink black tea and black tea to warm up.
summary
Tea, as an ancient and modern drink, is not only a liquid intake, it is a healthy attitude to life, a cultural inheritance, and a manifestation of the art of life.
Through reasonable tea drinking, we can not only enjoy the physical health brought by tea, but also experience the beauty of life in the fragrance of tea.
