Water is an integral part of the human body; it is directly involved in all vital processes.
The human body is 78% water, the quality of which affects our health. How much fluid should you drink daily? What is the best, safest and healthiest water? Does bottled water contain harmful impurities and preservatives? And how does elite water differ from ordinary dining room?
Experts of the Useful Program project at Inter, nutritionist Kateryna Kondratyuk and food quality and safety expert Elena Sidorenko, figured out how to choose, store and drink water correctly so as not to harm health.
Drinking water properties
According to experts, drinking enough water can significantly reduce the stress on the heart. Water thinns the blood and significantly reduces the risk of heart attack. It also reduces the risk of infectious diseases, removes toxins from the body and improves skin condition.
An adult needs to drink 30-40 ml of pure water per 1 kg of body weight in winter, in summer or with increased physical exertion - 50 ml. The loss of even 10% of fluid can have serious consequences for the body. Fatigue, infections, kidney stones, joint diseases, problems with digestion and metabolism - this is an incomplete list of diseases that are caused by a lack of water. Water not only nourishes cells, it flushes out toxins that enter the human body, simultaneously forming useful compounds of various chemical elements.
Today in Ukraine there are three main sources of drinking water: centralized water supply, underground sources (wells, pump rooms) and bottled water. In the production of the latter, natural mineral, artesian or municipal water is used.
One of the most important properties of drinking water is the degree of mineralization.
Drinking water composition
Any water, regardless of the water source, manufacturer, methods of purification and enrichment with microelements, geography and even the depth of the well is a unique cocktail of substances such as potassium, magnesium, iron, silver, sulfates, fluorine, iodine.
Ordinary table water usually contains up to 1 g / l of minerals. In the mineral-dining room - 1-8 g / l, and in the mineral-medicinal one - more than 8 grams of minerals per 1 liter of liquid. For daily use, it is recommended to drink water in which the concentration of minerals does not exceed 5 g / l.
Water of unknown origin, the quality and composition of which you are not sure about, can be hazardous to health.
So, when drinking water with an iron content above the norm, there is a risk of disrupting the liver and getting allergic reactions. The constant use of water with increased hardness leads to the accumulation of salts in the body and, ultimately, to joint problems, to the formation of kidney stones, gall and bladder stones. A low fluoride content in drinking water can lead to the development of caries.
In order not to be mistaken with the choice of drinking bottled water, expert on the quality and safety of products Elena Sidorenko recommends paying attention to such moments.
It should indicate the chemical composition, the place of water extraction, the date of issue, the batch number and the manufacturer's output data.The name of the water must be spelled correctly and the label must be clearly printed and well adhered.
Water in glass bottles retains its beneficial properties longer. If the container is made of low-quality plastic, when heated above 30 degrees, it can release toxic substances into the water. It is also important that the bottle and cap are clean and level, without mechanical damage. Polycarbonate containers are relatively safe - large containers in which water is supplied to offices and apartments. These bottles are designed for reusable use as they are more rigid and chemically resistant.
Storage conditions and periods
It is recommended to consume water within 3 months from the date of its production. In this case, there is a guarantee that the least amount of harmful substances from the plastic container will get into the water. If the label states that the shelf life of water is 1 year or more, be aware that this is practically impossible without the use of special preservatives.
