Types of beverages referred to as teas
Many beverages are referred to as tea, but fervent enthusiasts consider tea to be only that made from the Camellia sinensis plant, which thrives in China and India (green, black, white, oolong and red pu-erh teas). They differ in fermentation period and antioxidant content. All of these teas also contain caffeine and theine, which stimulate the nervous system. Infusions from dried fruits and herbs are commonly included under the umbrella of teas as well, although their properties diverge from those of traditional teas.
Green tea shrub – the power of antioxidants
Green tea can be produced through the fermentation process (although this is not necessary), and its leaves are merely dried, which allows them to retain most of the antioxidants they contain. One of these is the polyphenol galusan epigallocatechin (EGCG), which significantly increases the number of so-called regulatory T lymphocytes, cells responsible for the functioning of the immune system, resulting in anti-inflammatory and anti-cancer effects. Green tea displays multidirectional effectiveness and can prevent the development of bladder, breast, lung, stomach, pancreas, and colon cancer, as well as reduce the risk of disease and stroke. Research has confirmed its impact on fat burning and its anti-atherosclerotic effect through lowering cholesterol levels and reducing oxidative stress. Green tea aids in detoxifying the body, which can have a positive effect on skin health.
White liquid tea beverage
This white beverage owes its color to the production process. Tea shrubs are shielded from the sun's rays to avoid chlorophyll production, which imparts a green color, and then the leaves are dried to retain the maximum polyphenols. It can only be harvested by hand and in early spring when leaves are still young. Consequently, its price is significantly higher than that of other beverages.
Scarlet tea, the key to weight reduction
Individuals aiming to shed pounds and dealing with diabetes should consider incorporating scarlet tea into their diet. Pu-erh tea promotes fat tissue oxidation, regulates lipid metabolism, protects against arteriosclerosis, and aids in blood sugar level regulation. This tea variety is distinguished by its lengthy maturation period, imparting a robust flavor and fragrance.
Plant-based tea selections
Pure tea varieties – do not contain stimulating substances such as tina, theophylline, or theobromine, making them safe for children and pregnant women. They have a more intense effect than green tea due to their higher polyphenol content; they strengthen the immune system, protect against heart diseases and cancers. Nettle – not just a stinging plant, but also a medicinal one. Enhances liver function, cleanses the bile ducts and urinary tract, accelerates metabolism, and assists in the treatment of skin changes.
