Green tea is one of the three most powerful antioxidants that prolong human life. It contains many essential oils – stimulants of important processes in the body.
They have an effect on biochemical reactions, improving the well-being of a person. Not all of these substances have been studied, as well as the effect of green tea on the body. However, many useful properties of the product have been known for a long time. Today there is scientific evidence of these facts.
What is the difference between green tea and black
Both types of tea are harvested from the same tea bush (Camellia sinensis). The main difference between black and green tea in leaf processing technology.
If the collected raw materials are slightly steamed or slightly heated, or even simply dried in the sun for 2-3 days, it is fermented (oxidized) minimally – by 3-12%. So get green tea. The Chinese call it yellow.
To obtain black tea (red Chinese) you will need complete fermentation within 14-30 days. The sheet is specially crushed and dried by a special technology.
The composition and calorie content of green tea
Hot drinks cannot replace water, but they are important for health. The benefits and harms of green tea are related to the dry leaf chemistry. This indicator, like calorie content, is calculated based on 100 g of dry tea leaves. During the preparation of the drink, the substances pass into the water infusion.
The chemical composition of green tea
100 g of dry tea leaf contains:
proteins – 20 g fats – 5, 1 g carbohydrates – 4 g.
The product is rich in vitamins:
Thiamine (B1) – 0.07 mg-Riboflavin (B2) – 1 mg-Retinol (A) – 0.05 mg-Niacin equivalent (PP) – 11, 32 mg-Ascorbic acid (C) – 10 mg.
The mineral composition includes micro and macro elements: potassium (2,480 mg), phosphorus (824 mg), calcium (495 mg), magnesium (82 mg), sodium (82 mg), iron (82 mg), fluorine (10,000 μg )
Active substances such as catechins, carotenoids, tocopherols, polyphenols and caffeine were identified in the product.
