Black tea helps the relaxation of blood vessels, due to its flavonoid content, helping to prevent the oxidation of good cholesterol.
The black tea and green tea come from the same tree, but differ in that black tea has a look and a different flavor, because it has been fermented.
This tea goes through a production process that consists of a total of four stages: wilting, rolling, fermentation and finally drying.
Its most outstanding nutritional characteristic is that it has a slightly higher theine index than the rest of the teas, although it is very rich in minerals, such as zinc, calcium, chromium, magnesium, manganese, iron, potassium, phosphorus, fluorine. And aluminum.
Regarding its antioxidant power, a cup of black tea provides us with about two hundred milligrams of flavonoids, which for example help improve the ability of blood vessels to dilate and contract, something that reduces the risk of heart attacks.
It facilitates the non- oxidation of HDL (good) cholesterol, thus hindering the formation of atheroma plaques, clearly responsible for the vast majority of cardiovascular accidents.
In addition, as we could already see in previous lines, it contains fluoride, so black tea in turn collaborates in the prevention of dental cavities.
Benefits of black tea

- Thanks to its flavonoid content, it is useful to improve the capacity of both dilation and contraction of blood vessels.
- Reduces the risk of heart attacks.
- Helps HDL cholesterol (good cholesterol) not to oxidize.
- Prevents the formation of dental cavities.
Nutritional values of black tea
