Yes, the difference will be big, you need to drink only clean water! the same tea, juice have a sediment, and the water is clean and it immediately enters the bloodstream and cleanses the body. But keep in mind, 2 liters per day is a generalized figure, on average. Each person needs to drink their own norm, and in order to calculate it, you need to multiply your weight by a factor of 0.3 and then you will find out how many liters of water you need to drink per day
Personally, I prefer to drink pure water and drink it at the rate of 30 milliliters per kilogram of body weight. Much time has passed, but I am not changing my method. In hot climatic countries, people drink mainly green tea. But this is already a matter of taste for each person. I think that every person does what he thinks is right for himself. The basic rule is not to harm !!! Best regards.
64 years old. I never drank water, I felt sick from her. In old age, I succumbed to advertisements. In the morning 300-400ml and sometimes during the day. Not only is it through force, but also the weight is popped (I feel extra looseness and weight). From 57 kg I became 65. I am thinking to reduce the portions of water, because when I forget to drink, the weight decreases. And the salt, somehow, also began to act. Well her ...
Do doctors advise? Not for sure, these are the advice of traders-marketers selling bultilated water at a price higher than the price of gasoline! Doctors just urge to observe the measure in the use of water
The question is different .... where to get good (weighted by chemical composition) water. The problem of big cities and the water supply network. And no need to talk about filters, coolers, big bottles from stores (same g ... but).
There is no difference between tea, soup, watermelon and water in terms of water consumption. The body processes everything that gets into it. In the gastrointestinal tract, everything is first disassembled for parts, and then it is carried into the blood. Tea is a solution. After all the impurities have gone into the blood from it, ordinary water will remain, the same as if you drank it separately.
Another question is, can you drink so much tea? If there are no contraindications, then on health.
I think it's better not to replace water with anything ... we still need clean water. But from 3-4 cups of tea, there will definitely not be harm)) I do just that, by the way. I usually drink Evalar bio green tea or simple milk oolong ... I feel great, always cheerful, no sleepiness ... so I advise you to try doing this way)
If you give an oak tree, you will not feel it. But best of all, you must remember that all people are different, only they buried them equally before everyone else. Considering our medicine, it is best to keep a health diary and, at least once a week, briefly describe your feelings. much will become clear. and there is no need to make jerky movements, especially in nutrition. Health to you! svarozich.
A liter of water is not equivalent to a liter of any solution for two reasons:
1) Physicochemical reason . The solution can contain substances with different volumetric activity, let's call it that. Some substances occupy a part of the volume that water could take, thus reducing the volume of water in the volume of the solution (in 1 liter of solution, not 1 liter of water, but 995 ml, for example) - this can happen both with and without dissolution, and in the first case, the substitution occurs only partially. Other substances absorb water and become denser (sugars, for example, which can be contained in sweet drinks, including juices), while not significantly changing in volume, thus requiring a larger volume of water for the same volume of solution (in 1 liter of solution not 1 liter of water, but 1005 ml, for example) - if such substances are not yet absorbed in the intestine (various metal oxides that may be contained in lactic acid products, and indigestible fibers that may be contained in fresh juices), then they do not allow absorption and water; this is the so-called osmotic activity. The final result will depend on the ratio of these substances, but it, as a rule, is in the direction of decreasing the volume of water in the solution.
2) Biological at rank . The solution may contain biologically active substances that affect the frequency and intensity of urination. So, diuretics (tea and coffee contain xanthines, caffeine and theophylline, which are such) increase the excretion of water from the body. In addition, the solution may contain substances that affect the absorption of other substances and water. So, tannins (tea and coffee also contain them), bind proteins of the walls of the gastrointestinal tract, making it difficult to absorb (by the way, because of the tannins persimmon "knits") the same water.
So , sweet tea, in comparison with water, contains sugar that retains water, tannins impair the absorption of water and enhance its excretion of xanthine. A lively mixture.
Thus, for many reasons, less water enters the body from an aqueous solution than from water itself, but ... there will not be much difference anyway , because the volume received and retained in the body will ultimately change not by 3, not 2, or even 1.5 times, but much less.
Why do experts, when talking about drinking, talk about water? Because if you recommend anything else to the layman, he will get drunk with this, and there, in addition to osmotic, diuretic and tannin-active substances, there are substances with other biological activity, including unwanted ones.
Everything that has color, smell and taste is food. So you need to drink water, not just strictly 2 liters a day, but how much the body needs (he will tell you himself). In addition, water perfectly satisfies hunger, filling the stomach and kidneys like it.
You cannot equate drinking water and drinking green tea (even if you drink it without sugar). If only because green tea contains caffeine, which has a stimulating effect on the body. Naturally, water has no such effect.
Just one example - immediately after drinking green tea, blood pressure rises, but after a while it decreases. If you drink tea throughout the day, it is fraught with constant "surges" of pressure. And this is just one way of influencing the body. So, of course, you cannot replace the allotted two liters of water with two liters of green tea.
And why we are recommended to drink more water, you can read the article on our website.
Not doctors, but "experts". Doctors are generally aware that the human body has a built-in regulation mechanism that works quite correctly, and does not allow a person to miss the lack of fluid in the body (if anyone do not understand, then we are talking about a feeling of thirst).
