watermelons and cucumbers instead of water

Currently, some people with influenza only supply their bodies with fluids through coconut water, freshly squeezed juices, and fruits. Others drink water - and there are different names and sources. The Drinking Water Ordinance and the Mineral and Table Water Ordinance regulate various requirements such as declaration, origin, production, mineral content, heavy metal content, microbiology, etc. The variety of terms and the details of the ordinances can be confusing.

Drinking water must be of such a nature that consumption or use does not cause any harm human health, particularly from pathogens. It must be pure and fit for social consumption ( drinking water ordinance ).

Mostly  63% of Germans drink tap water every day ( frozen drinking study ). Regionally known as tap water or crane water or also lovingly called Kraneberger.

Natural mineral water must be officially recognized. To be "naturally pure" as prescribed, it has to come from underground water sources protected from pollution and be bottled at the start.

Springwater comes from underground reservoirs and can be obtained from natural or artificially developed sources. Table water can be obtained from drinking water (tap water), mineral water, natural brine, or seawater.

Healing water comes from deep underground water resources and is entirely pure from its origin. It is precious water because its content of minerals and trace elements has a proven and officially confirmed health effect.

In the search for the "right" water, you will find many terms such as exclusion zone water (EZ), water can store (light) energy, energized and levitated water, H3O2, etc. I recommend this for this area Book by Dr. Pollack. First, let's focus on the question:

Waterways: How does it get into the blood and cells as a drink (or food) via the intestine?

As a polar molecule, water cannot diffuse well through cell membranes' lipid layer. There are so-called aquaporins - a group of water channel proteins. They are pore-forming transmembrane proteins that enable the transport of water molecules through plasma membranes by facilitated diffusion but are impermeable to ions (also for H 3 O + and dissolved minerals) and small metabolites.

The main driver for the passive transport of water is the sodium ion (Na + ), which generates the necessary osmotic pressure and is strictly hormonally regulated.

Aquaporins also play a significant role in " brain cleaning " during sleep (see also glymphatic system ), where there is a greater exchange of fluids.

The aquaporins are essential in the reabsorption of water by the epithelial cells in the small and big intestines and the renal epithelia. Reabsorption also plays a significant role in the gastrointestinal tract because around 6.5 liters of water are absorbed in the minor intestine and 1.3 liters in the colon.

Bioavailability: How do the minerals dissolve in the water get into the blood and cells via the intestines?

It is often discussed whether the minerals z. B. are bioavailable in drinking water (i.e., can be absorbed by the body) and, if so, in what form

Various aspects play a role:

·        inorganically or organically bound form

·        concentration

·        Function as an electrolyte for the water-electrolyte balance

·        hormonal regulation

Let us consider the intake of the most crucial quantity elements of minerals.

Let's start with sodium, as it is the most critical extracellular cation and ensures the correct osmotic pressure and, together with water, is subject to tight hormonal regulation. It is absorbed in the stomach tract, and the largest source is table salt (NaCl). Therefore, the sodium supply from mineral water plays a minor role - so you can choose a water with a low sodium content and see that it contains more potassium. This is because potassium is the most critical intracellular cation and is sufficiently absorbed through food—calcium and phosphate are stored as calcium phosphate in bones and teeth as a storage form. The bioavailability is given for calcium with 25 to 45% and magnesium with 35 to 70%. For a long time, the bioavailability of minerals from the water was considered to be relatively low. However, this could be refuted in studies on humans using modern tracer methods (= administration of stable isotopes). The bioavailability of calcium from water is just as high as from milk.

Further information on the bioavailability of trace and bulk elements can be found in

·        Iron uptake well as heme, poorly as an inorganic compound.

·        Organically bound zinc is adequate, harmful as an inorganic salt.

·        Magnesium: sulfate, phytate, gluconate bad; good: fumarate, lactate, orotate, phosphate, pidolate, taurine, chloride, or citrate.
