Is water with scale dangerous for health.

Scum from the kettle : doctors explained what it does to our body

White flakes in the water, a whitish bottom – this is the picture we often see in our teapots. Due to hard water, scale forms on the walls, which is not so easy to remove. And is it necessary, if after a few days it appears again? On the one hand, it is disgusting to drink tea with “additives”, on the other hand, there is an opinion that such water can even be useful! Allegedly, this is how we can get additional minerals directly from a glass of water, informs Ukr.Media.

Doctors have an unequivocal opinion: water with scale cannot be an additional source of calcium, although it is contained there.

Scale on a teapot, of course, is not dirt, scientifically speaking, scale is a deposit of mineral salts. There are some minerals in tap water, and when boiled, they stick to the walls and form whitish separations and flakes.

The main components of these “flakes” are — calcium carbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride and magnesium chloride. It turns out that scale is a mineral, not dirty, not harmful, but also not useful, if only because there is very little of it in water. The main source of calcium and the same magnesium for us is food.

The average daily rate of water (2 liters) contains about 60 mg of calcium, while we need to consume 800 mg of the mineral per day, the researchers specified. — But the calcium content in many common products is much higher than in water.

Opponents of carbonated water are sure that it can provoke the growth of kidney stones. But this opinion can also be called a mistake. There are not enough minerals in the water that would lead to the formation of stones. And they are in the wrong chemical form.

The main component of urinary calculi is calcium oxalate, which differs from the components of scale — calcium carbonate, magnesium carbonate, calcium sulfate, and others, scientists reassure. So there is no need to worry about drinking water causing stones.

Also, plenty of water, with or without limescale, is one of the best ways to stop or prevent stone formation.

If we talk about the damage of scale, it damages the equipment the most, not our body. The efficiency of the kettle decreases, as scale reduces thermal conductivity. And we suffer more from aversion to water with scale flakes than from a drunk glass of such water.
