Properties of Black Tea
Black tea is an ancient beverage derived from the leaves of Camellia sinensis, a plant of the Theaceae family. What distinguishes black tea from other types is the full oxidation the leaves undergo, which gives it its characteristic brown color.
Properties of Black Tea
A cup of black tea contains about 99% water, a very low amount of carbohydrates (0.30g), and significant levels of minerals such as iron, magnesium, phosphorus, sodium, and especially potassium. It also contains smaller amounts of zinc, vitamin B2 (riboflavin), and vitamin B9 (folic acid). Black tea has a higher caffeine content than other teas, with a 200ml cup containing slightly less caffeine than an espresso coffee.
Health Benefits of Black Tea
Thanks to its high content of theophylline, theobromine, and caffeine, black tea is an excellent natural stimulant, ideal for regaining concentration and energy. Although in smaller amounts than green tea, black tea contains polyphenols and tannins that have antioxidant effects. Regular consumption may help reduce cholesterol levels.
Are There Contraindications for Black Tea?
Yes, but only in cases of excessive consumption. The caffeine may cause agitation, similar to drinking too many espressos. Otherwise, it is a healthy beverage rich in beneficial properties for the whole body.
