Tea is the best beverage for middle-aged and elderly people. Scientific analysis has shown that tea contains proteins, fats, over 10 types of vitamins, as well as nearly 300 components such as polyphenols, caffeine, and lipopolysaccharides, which can regulate physiological functions and play a variety of health-preserving and pharmacological roles. What are the greatest benefits of drinking tea? 1. Improves Muscle Endurance. There is an antioxidant in tea called "catechins," which can increase the body's ability to burn fat, improve muscle endurance, help fight fatigue, and increase the duration of physical exercise. Regular consumption of green tea shows the most significant effects. 2. Fights Ultraviolet Radiation. Tea polyphenols are water-soluble substances. Washing your face with tea water can remove facial grease, tighten pores, and have disinfecting, sterilizing, and anti-aging effects on the skin. It also helps reduce damage from ultraviolet rays in sunlight, acting as a natural "sunscreen." 3. Maintains Body Shape. The caffeine in tea can promote the secretion of gastric juice, aid digestion, and enhance the body’s ability to break down fat. Regular tea consumption can reduce waist circumference, lower body mass index (BMI), and thus help prevent diabetes and cardiovascular diseases. 4. Protects Against Radiation. Tea polyphenols…

Green tea is one of the main types of tea in China, belonging to the category of non-fermented teas. It is made from fresh tea leaves through processes such as fixation, rolling, and drying. Notable varieties of green tea include Biluochun, Zhaopo tea, West Lake Longjing, Lushan Cloud Mist, Dawu green tea, and Jingu Luhao, among others. Green Tea Production Process The processing of green tea can be simply divided into three steps: fixation, rolling, and drying, with the key step being fixation. Fresh leaves undergo fixation, which deactivates enzymes, allowing the various chemical components within to undergo physical and chemical changes primarily due to heat, forming the characteristic qualities of green tea. 1. Fixation During withering and fixation, the internal moisture of the leaves evaporates, and the enzymatic activity is destroyed, preventing further oxidation. This allows for the evaporation of low-boiling-point aromatic compounds while preserving high-boiling-point aromatics, locking in the intrinsic aroma of the tea. As the temperature rises, high-boiling-point aromatic substances become more prominent. This process also evaporates moisture from the leaves, making them softer and preparing them for rolling. Shaking fixation involves lifting the leaves to facilitate moisture loss and the release of grassy odors, allowing a…

What precautions should be taken when drinking tea? Tea is closely related to our daily lives, and there are many benefits to drinking it, such as fat reduction and digestion aid. However, there are also several considerations to keep in mind to ensure that drinking tea truly promotes health. Here are some points worth noting. What to Consider When Drinking Tea Regularly 1. How Many Infusions Can a Cup of Tea Have? The number of times tea can be steeped depends not only on its tenderness but mainly on the processing method used. During initial processing, if the leaves are cut, the tea essence will be easier to extract. Conversely, coarser, older, and intact leaves release their flavors more slowly during steeping. For most green teas, the first infusion releases about 50% to 55% of the soluble substances; the second infusion typically extracts around 30%; the third yields about 10%; and the fourth provides only 1% to 3%. From a nutritional standpoint (considering vitamins and amino acids), 80% of these components are extracted in the first infusion, about 15% in the second, and by the third infusion, nearly all have been extracted. In general, black teas, green teas, and flower…

In our daily lives, coffee and tea are indispensable beverages for many people. Not only do they have unique flavors, but they are also popular due to their significant effects in boosting alertness and mental clarity. For many, having one or two cups of coffee or tea each day has become a habit, driven not just by their enticing aromas but also by the invigorating effects they provide. Some people are particularly fond of tea, not only for its stimulating properties but also because of the health benefits associated with the polyphenols found in tea leaves. First, let's delve deeper into the composition of tea. There are three main components closely related to tea leaves: polyphenols, caffeine, and theanine. Polyphenols are abundant in tea and are responsible for the astringency in taste. They include flavonoids, epigallocatechin, gallate (EGCG), and other catechins. Caffeine is a potent central nervous system stimulant and the key component that provides the energizing effect in tea; it is also the source of the bitter taste. Theanine gives tea a fresh and pleasant flavor and helps the body resist fatigue for longer periods.   Now let's look at the composition of coffee. The stimulating substances in coffee…

Tea, by nature, is cold and can help clear the mind and soothe the spirit. Different people have different constitutions, which means they should drink different types of tea. Therefore, choosing the right tea and drinking it well starts with understanding the nature of the tea and the suitable groups of people for each type. Nature of Teas 01 Green Tea: The core process is "fixation," making its nature cold. People with a hot constitution, high stomach fire, or abundant energy can benefit from drinking green tea, as it has great effects in clearing heat, refreshing the mind, and boosting alertness. Green tea also has excellent radiation protection benefits, making it ideal for those who work on computers. White Tea: The core process involves "withering and sun drying" followed by natural storage, which transforms the tea's nature from cold to cool and then to mild. Fresh white teas share many properties with green tea, but the most significant difference is that while aged green tea becomes like grass, aged white tea becomes even more precious. As it ages, old white tea becomes even milder, making it suitable for a wider range of people. Oolong Tea (Blue Tea): The core process…

Drinking green tea does not cause heatiness. As a non-fermented tea, green tea has a slightly cool nature. It is rich in caffeine and catechins, which can accelerate bodily excretion and promote metabolism. These substances also help to alleviate heatiness and reduce dryness. Moderate consumption of green tea will not only prevent heatiness but also replenish the body's moisture and provide a cooling effect to relieve summer heat. Benefits of Drinking Green Tea First, green tea has excellent properties for refreshing the mind and alleviating fatigue due to the presence of caffeine, which stimulates the central nervous system, enhancing mental alertness and focus. Second, the caffeine in green tea can aid digestion by stimulating gastric juice secretion, thus helping with digestion. Third, green tea contains catechins, which are beneficial for cardiovascular health and have a strengthening effect on the heart. Fourth, green tea helps protect teeth. The rinsing action of tea water is effective, and the fluoride in tea can help prevent tooth decay and promote dental health. Fifth, green tea contains polysaccharides that possess anti-aging properties and can help protect against radiation. Consuming green tea does not lead to heatiness. Green tea possesses numerous benefits, including refreshing the mind,…

Yunnan white tea is mainly produced in Jinggu and is classified into two categories based on the tenderness of fresh leaves: Dabaitcha (single bud) and Moonlight White (one bud with one or two leaves). Moonlight White, also known as Moonlight Beauty, has black surfaces and white undersides of its leaves. The contrast of black and white makes the overall appearance of a single bud with two leaves resemble the moon in the night sky, hence the name. Few people are familiar with Jinggu white tea. Scholars have conducted research and analysis on it. In this article, let’s explore the differences between Jinggu white tea and Fuding white tea to establish a scientific understanding! No.1 Water Soluble Extracts: Water soluble extracts are a comprehensive reflection of the main taste and color substances in tea infusion. The amount indicates the quantity of soluble materials in the tea, marking the thickness and intensity of the infusion, which is positively correlated with tea quality. According to the data, the range of water soluble extracts in Fuding white tea samples is 33.28% to 40.39%, with an average of 37.52%. For Jinggu white tea, the content ranges from 40.74% to 46.72%, averaging 44.44%. These results indicate…
