Currant is called the record for the content of ascorbic acid among berries and fruits. There are so many of its ripe berries that only 20 pieces of eaten fruit will satisfy the body's daily need for vitamin C. The important point is that already after a couple of weeks after maturation, more than 70% of the ascorbinka in the composition is destroyed.
In addition, black berries contain vitamins A, E, K and a number of B vitamins (among them thiamin, riboflavin, nicotinic acid, pantothenic acid, pyridoxine).
Taste shades of black currant due to its organic acids and tannins. It is well known as an anti-cold remedy due to the presence of phytoncides in it. The latter are bioactive substances that defeat viruses and microbes. Berries also include essential oils, pectins.

It also demonstrates the disinfecting effect, which makes the fruit applicable for flu, sore throat, and inflammations in the mouth.

The disinfecting and bactericidal action of the berries is also due to the content of anthocyanins in them. They are glycosides, which also provide a shade of berries. It is noteworthy that the body itself does not produce anthocyanins, so it is important that they come from food. In addition to combating viruses and bacteria, these glycosides improve the quality of connective tissue, make the vascular walls more durable and elastic.

The walls of the latter become less fragile and more elastic.
Under the influence of phytoncides and antioxidants, the level of "bad" cholesterol in the blood decreases, the formation of cholesterol plaques on the inner wall of the blood vessels stops. Nicotinic acid "helps" the capillaries, small vessels penetrating every organ and tissue.Under her influence, capillaries become more durable, but at the same time, permeable. This, in turn, provides better nutrition for each organ.
