On the holidays, all the major stores are selling health products such as “Golden Partner” and “Melaton Platinum”. The banner is nothing more than supplementing the nutrition that the human body lacks and balancing the functions of the human body. Calcium, iron, zinc, selenium... These elements are most frequently input into our minds by various advertisements, making us a little dizzy. In fact, the test proves that the combination of various elements in tea is the most "golden". In this issue, we have a comprehensive understanding of how much secret tea has.
a set of data
The chemical composition of tea is composed of 3.5% to 7% of inorganic matter and 93% to 96.5% of organic matter.
There are about 30 inorganic mineral elements in tea. The main ingredient is potassium. About 50% of the total minerals, phosphorus accounts for about 15%, followed by calcium, magnesium, iron, manganese, chlorine, aluminum, as well as trace components such as zinc, copper, fluorine, sodium, selenium and so on. Compared with other plants, tea has a high content of potassium, fluorine and aluminum.
The organic compounds in tea mainly include proteins, lipids, carbohydrates, amino acids, alkaloids, tea polyphenols, organic acids, pigments, aroma components, vitamins, saponins, sterols and the like.
Tea contains 20% to 30% of leaf protein, but only about 3.5% is soluble in tea soup.
Tea contains 1.5% to 4% of free amino acids, and there are more than 20 kinds, most of which are essential amino acids.
Tea contains 25% to 30% carbohydrates, but only 3% to 4% soluble in tea soup.
Tea contains 4% to 5% lipid, which is also essential for the human body.
Three great tools
Under the support of a strong set of data, we have summarized five "tools" to explain the health effects of tea.
Sharp weapon 1: Vitamin C is higher than fruit
The content of vitamin C in tea is high, generally up to 100 mg to 250 mg per 100 g of green tea, and the content of high-grade Longjing tea can reach more than 360 mg, which is higher than that of lemon and citrus.
Don't underestimate this small blade. The vitamin content in it makes countless fruits and vegetables go down the drain. Just 25 grams of tea a day, the vitamin C you need for a day is basically guaranteed.
Sharp 2: Anti-aging tea polyphenols
Vitamin E has been hailed as a veteran ingredient in anti-aging. The anti-aging effect of tea polyphenols in tea is 18.5 times that of vitamin E.
Sharp weapon three: beauty vitamin B
The vitamin B in the tea can be completely dissolved in the tea soup, so the tea can be completely absorbed.
Don't ignore the protective function of vitamin B on the skin, such as vitamin B, which is called beauty vitamin, which can promote metabolism and make capillary blood flow smooth. Insufficient vitamin B can cause small wrinkles, rough skin, sun allergy, acne and other symptoms.
