Nitrates in drinking water, angels or demons?

Nitrates are regulated in drinking water in France, with a maximum of 50mg/l. However, this 20-year-old rule seems controversial.

Our main sources of nitrates are vegetable food: beets, lettuce, spinach, potatoes, etc…

For example, consuming 50 grams of spinach provides 250mg of nitrate, which is as much as 5 liters of water with 50mg/l of nitrate ….

And I’m not hiding the truth, 50gr of spinach is very little!

Nitrates: beware, they are good for your health!

Fresh and clear, the water that flows from our tap suddenly becomes dubious when the threat of nitrates looms…


Modern science considers nitrates to be friends (not to be confused with nitrite salts, a controversial preservative in deli meats).

But of course, the regulations have not evolved, while the benefits of nitrates are so well known that they have been made into medicines, available by prescription. They are used to treat heart failure, high blood pressure or to help athletes breathe better at high altitudes, and to bring oxygen to the muscles.

They reduce stress and lower tension.

“The scientists have moved on! ” These are the words of Dr. Gilles Demarque, nutritionist…


The WHO has limited 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.

Purificateur d'eau LaVie

You can use tap water after LaVie treatment for infants.

Indeed, nitrates are regulated at a maximum of 50 mg/l in tap water, and the Anses gives a maximum of 50 mg/l in baby bottles for infants under six months.

LaVie® UV-A water purifiers operate without filters or maintenance and allow you to purify your tap water in 15 minutes.

They use an innovative, patented technology exclusive to LaVie®: the photolysis of chlorine by UV-A radiation.

This treatment allows the removal of chlorine and its by-products, chemical compounds such as certain pesticides or traces of medication, tastes and odors that can be found in tap water.

The result, very qualitative, allows to draw a definitive line on the consumption of water in plastic bottles.

We must not confuse the environment with our bodies.

An excess of nitrates in a river will cause green algae, which will capture dissolved oxygen and endanger the ecosystem, it is true, and the amount 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 scourge for the environment, it only takes a heavy rainfall after a fertilizer application to bury the bulk of the contents in the groundwater…

On the other hand, the ingestion of this product by the human body, within reasonable limits compared to the intake from vegetables, is not dangerous at all, on the contrary.

In the filtering carafes, resin-filled balls are inserted to replace nitrates with sodium ions (table salt, which is already absorbed in excessive quantities in ultra-processed foods). Of course, it also reduces calcium by 90%, which is largely bioavailable in water and necessary for our health, it allows for example to convey orders from the brain to the muscles.

Obviously, these beads, loaded with nitrates, become very difficult to recycle, and are generally not recycled because it would be too expensive.

I conclude with a note of common sense: a product that is beneficial (and indispensable) for health provided by our vegetables can hardly be dangerous when absorbed in liquid form in good water.

To say otherwise would be like saying that the vitamin C in cabbage is good, but that taking a vitamin C pill would be dangerous…

In (bio)chemistry, it is all a question of quantity, we must not abuse anything, but consume healthy and varied products, which provide us with what we need to build our body and our immunity.

To your health!
