Nitrates in drinking water, angels or demons?
Nitrates are regulated in drinking water in France, with a maximum of 50 mg / l. However, this 20-year-old rule seems controversial.
Our main sources of nitrates are plant foods: Beets, lettuce, spinach, potatoes, etc.
For example, consuming 50 grams of spinach provides 250mg of nitrate, or as much as 5 liters of water at 50mg / l of nitrate ....
And I'm not hiding the truth from you, 50gr of spinach is very little!
Nitrates: be careful, they are good for your health!
Fresh and clear, the water flowing from our tap suddenly becomes doubtful when the threat of nitrates looms ...
Modern science considers nitrates more like friends (not to be confused with nitrite salts, the controversial preservative of cold meats).
But of course, the regulations have not changed, while the benefits of nitrates are so well known that drugs have been manufactured, available by prescription. They are used to treat heart failure, hypertension or to help athletes breathe better at altitude, and to provide oxygen to the muscles.
They reduce stress, and lower blood pressure.

“Scientists have moved on!” These are the words of Dr. Gilles Demarque, nutritionist…
The WHO has contented itself with limiting them to 50mg / l, without restricting them to children or pregnant women, while we still consider them dangerous for infants under 6 months in France.
You can use tap water after LaVie treatment for infants.
LaVie UV-A water purifiers® work without filters or maintenance and allow you to purify your tap water in 15 minutes.
They use an innovative technology, patented and exclusive to LaVie®: the photolysis of chlorine by UV-A radiation.
This treatment allows the removal of chlorine and its derivatives, chemical compounds such as certain pesticides or traces of medication, and tastes and odours that can be found in tap water.
The result, which is very qualitative, makes it possible to draw a definitive line on the consumption of water in plastic bottles.
The carbon footprint linked to the manufacture of the aluminium tube of the UV water purifier is neutralised in a few days of use compared to the equivalent consumption of water in plastic bottles.
We must not confuse the environment with our body.
An excess of nitrates in a watercourse will cause green algae, which will capture dissolved oxygen and endanger the ecosystem, it is true, and the quantity that Brazil pours into the Amazon river endangers Martinique and Guadeloupe, it is a proven fact, and a real environmental disaster.
Modern agriculture is a plague for the environment, it only takes heavy rain behind a spread of fertilizer to bury the bulk of the content in groundwater ...
On the other hand, the ingestion of this product by the human body, within reasonable limits compared to the intakes by vegetables is in no way dangerous, on the contrary.
Note that in filter jugs, beads filled with resin are inserted to replace nitrates with sodium ions (table salt, already absorbed in too large a quantity in ultra-processed foods). Of course, it also reduces calcium by 90%, which is largely bioavailable in water and necessary for our health, for example it helps carry orders from the brain to the muscles.
Obviously, these beads, loaded with nitrates become very difficult to recycle, and are generally not, because it would be too expensive.
I conclude with a common sense note: a product which is beneficial (and indispensable) for the health provided by our vegetables can hardly be dangerous when it is absorbed in liquid form in good water.
To say otherwise would be to say that the vitamin C in cabbage is good, but taking a vitamin C tablet would be dangerous ...
In (bio) chemistry, everything is a question of quantity, we should not abuse anything, but consume healthy and varied products, which provide us with what to build our body and our immunity.
