What 21 Research Say About Uncooked Water and Your Well being


Key Takeaways

Uncooked water is water that hasn’t been filtered, heated, or handled with any chemical substances to take away pathogens and pollution.
Proponents of uncooked water declare it’s good for you as a result of it gives wholesome micro organism and minerals and doesn’t comprise fluoride or chlorine.
The reality is that uncooked water is more likely to comprise pathogens and pollution, and there are straightforward, secure, and low-cost methods to take away chlorine and fluoride out of your water if you wish to.

What do you consider if you hear the time period “uncooked water?”

Most likely one thing like this: 

raw water

Ahh sure, clear, clear, unadulterated spring water from deep inside the Earth, naturally purified by Mom Nature. 

For those who have been to have a look at that water by a microscope, although, it might look extra like this:

water on microscopewater on microscope

Not fairly so interesting. 

In accordance with proponents of uncooked water, all of the stuff you see in that microscope picture is what makes uncooked water good for you.

That’s proper—the microbes, micro organism, and different goodies floating in that water does a physique good, and filtering, heating, or in any other case processing the water removes these helpful properties.  

Additionally they declare that what uncooked water doesn’t comprise is equally vital—specifically chemical substances like fluoride and chlorine.

In accordance with uncooked water advocates, uncooked water offers you the most effective of each worlds: no harsh chemical substances or industrial pollution, together with the minerals and microbes your physique wants.

Are they proper? 

Are the remainder of us compromising our well being by ingesting artificially processed, unhealthy water? 

The quick reply isn’t any—ingesting uncooked water is pointless, costly, and probably harmful.

If you wish to know extra concerning the uncooked water fad, together with what uncooked water is, why individuals drink it, and what science has to say about it, preserve studying.

What Is Uncooked Water?

The Oxford English Dictionary defines “uncooked” as “(of a fabric or substance) in its pure state; not but processed or purified.”

Uncooked water is water collected from the outside—sometimes from streams or springs—that hasn’t undergone any type of filtration, remedy, or heating to kill pathogens and take away contaminants.

So, the method for accumulating uncooked water is to get a jug, discover a stream, spring, or different physique of water in nature, fill it with water, and be in your merry method. 

In fact, in the event you don’t dwell subsequent to a stream or don’t wish to go to the difficulty of accumulating the uncooked water your self, you could find a number of firms which might be glad to promote it to you on a subscription foundation. All for an inexpensive worth of $6.40 per gallon—solely twice as a lot as gasoline! 

So, how does uncooked water differ from faucet water?

Many of the water individuals drink comes from public water remedy crops, which use a multi-step course of involving filtration and chemical substances to take away contaminants and kill microbes. Due to the Secure Consuming Water Act of 1974, these crops check for 91 totally different potential contaminants to make sure they’re inside secure limits.

In 24 to 36 hours, water that was blended with sewage is separated, purified, and launched again into the wild or despatched to a different remedy facility earlier than it turns into ingesting water once more. 

Any water within the U.S. that’s destined to turn out to be ingesting water additionally has fluoride added to it to assist cut back the chance of cavities. 

Chances are you’ll be questioning how uncooked water differs from effectively water.

In spite of everything, effectively water doesn’t bear any type of sanitization or filtration, so it’s kind of the identical as uncooked water, proper? 

Not precisely. 

Properly water is gathered by drilling deep into the Earth to achieve the groundwater, sometimes by a number of layers of rock. Groundwater will be as shallow as a number of ft or as deep as 30,000 ft beneath the floor, however most wells are positioned in areas the place the groundwater is a number of hundred ft deep.

This deep layer of grime, sand, and rock acts as a surprisingly efficient pure filter, which is why most non-public wells present water that’s inside the authorities requirements for water remedy crops. That stated, it’s all the time doable for environmental toxins or waste to pollute wells, which is why wells have to be examined not less than yearly to make sure the water is secure to drink.

The underside line, although, is what though effectively water will not be as reliably clear as water from a remedy plant, each are a lot, a lot cleaner than water from streams, rivers, and is derived.

Many of the water that makes its method into streams, rivers, and is derived comes from rain or snow soften, and it hasn’t undergone any type of filtration or remedy. 

Rain and snow additionally accumulate pollution from the air that are carried into springs, streams, and rivers.

As you’ll be taught in a second, because of this any pollution or pathogens which might be on or close to floor degree can simply make their method into uncooked water.

Abstract: Uncooked water is water that hasn’t undergone any type of filtration, purification, or chemical remedy to take away pathogens or pollution.

Why Do Individuals Drink Uncooked Water?

cold raw watercold raw water

To advocates of uncooked water, common bottled, faucet, or effectively water is akin to processed meals. Uncooked water, alternatively, is the equal of natural greens.

That’s how they see it, anyway.

There are two major causes uncooked water advocates declare it’s higher for you than faucet, effectively, or bottled water: 

They declare uncooked water has wholesome micro organism that you may’t get from faucet, effectively, or bottled water.
They declare that uncooked water comprises minerals that you may’t get from faucet, effectively or bottled water.
They declare that uncooked water doesn’t comprise dangerous compounds like chlorine and fluoride which might be present in faucet, effectively and a few bottled water.

Let’s break down these claims.

Uncooked Water and “Wholesome” Micro organism

First, it’s true that uncooked water comprises extra wholesome micro organism and minerals than faucet water.

Ideally, faucet water comprises just about no micro organism and really small quantities of minerals. In reality, these are two of the targets of water remedy—eradicating probably problematic micro organism and unsafe minerals.

What uncooked water evangelists don’t let you know, although, is that uncooked water may probably comprise giant quantities of unhealthy micro organism and minerals. 

For instance, typhoid is a lethal micro organism that thrives in water, and it’s killed hundreds of thousands of individuals simply within the 20th century. The first method typhus is unfold is by ingesting water contaminated by animal or human feces.

Dysentery is one other probably deadly illness that’s typically brought on by the micro organism shigellosis, which thrives in water.

Cholera is a bacterial an infection that kills anyplace from 30 to 130,000 individuals yearly, principally in undeveloped international locations with poor water sanitation. 

In reality, a doctor named John Snow was in a position to deduce that cholera was unfold by contaminated water earlier than scientists even knew germs existed. How? By monitoring cholera instances round London and utilizing statistics to find out that the almost certainly reason behind the outbreak was a single contaminated effectively. 

In fact, it’s all the time doable that uncooked water may comprise benign or helpful micro organism, too, like Bifidobacteria, B. breve, and B. animalis. Perhaps. 

There’s merely no method of figuring out precisely what’s in uncooked water, although.

It may have wholesome micro organism, benign micro organism, or probably life-threatening micro organism. 

With out testing the water for a variety of potential pathogens, or killing every part to be on the secure aspect, there’s no option to know what you’re placing into your physique if you drink uncooked water.

Is the small potential good thing about ingesting a handful of wholesome micro organism definitely worth the threat of presumably consuming lethal micro organism? 

Most likely not. 

In fact, uncooked water can comprise various different potential pathogens like viruses, amoebas, and different parasites, so micro organism aren’t your solely concern. 

For instance, Cryptosporidiosis is a situation brought on by microscopic parasites that make their method into streams, rivers, and lakes from animal feces. This is likely one of the most typical causes of water-borne sickness within the U.S., and it causes extreme diarrhea just like dysentery.

When confronted with info like this, some uncooked water advocated will fall again on the “however our ancestors drank uncooked water” argument. 

Certain, they did, and so they died by the hundreds of thousands from illness.

They knew this, too, which is why there are data courting again to 1,500 BCE in Sanskrit and Greek detailing numerous strategies to purify water, similar to filtering by charcoal, straining, boiling, exposing water to daylight, and so forth.

Uncooked, untreated water has all the time been a possible risk to human well being, and that’s nonetheless the case now.

Abstract: Uncooked water can probably comprise any variety of probably lethal micro organism, viruses, and parasites that may trigger all kinds of illnesses, even in developed international locations. 

Uncooked Water and “Wholesome” Minerals

It’s true that uncooked water comprises extra minerals than faucet or bottled water. 

It is because as water seeps by grime and flows over rock, it dissolves small quantities of assorted minerals that blend with the water.

And a few of these minerals will be good for you.

Calcium, for instance, typically leaches into water when a stream passes by an space containing limestone (which is excessive in calcium).

The identical factor can occur with rocks and grime containing calcium, magnesium, manganese, and potassium. When water comprises further minerals obtained from nature, it’s often known as “exhausting” water.

How a lot of those minerals are you truly getting, although? 

Properly, in accordance with the U.S. Geological Survey, “reasonably exhausting” water comprises 60 to 120 mg of minerals per liter. Most of that can be calcium carbonate, solely 40% of which is precise calcium (the opposite 60% being carbonate).

This implies a liter of water (~¼ gallon) comprises 24 to 48 mg of calcium. The reference every day consumption for calcium is 1,000 mg per day. To get that a lot calcium from uncooked water, you’d must drink 10 to 20 gallons of reasonably exhausting water per day.

Or, you would simply eat a midway nutritious diet and get that a lot calcium from a number of servings of greens and dairy.

So, the primary drawback with the “uncooked water has minerals” argument is that it has virtually no minerals. 

The second drawback is that it might additionally comprise many compounds that aren’t wholesome.

For instance, poisonous compounds like lead, uranium, arsenic, and cadmium may be in uncooked water, or any water that hasn’t been filtered.

Granted, these supplies are most typical in groundwater contaminated by industrial air pollution or lead plumbing, however they may also be present in uncooked water collected from streams, rivers, and so forth. 

Abstract: Uncooked water doesn’t comprise practically sufficient minerals to make a big influence in your well being, and it might additionally comprise probably dangerous minerals, metals, and different compounds.

Uncooked Water and Chlorine and Fluoride

Most faucet and bottled water comprises chlorine and fluoride in the USA.

These two chemical substances are added to ingesting water to kill pathogens and enhance dental hygiene, respectively. In fact, uncooked water by no means undergoes processing and doesn’t comprise both of those chemical substances, which proponents say is an effective factor.


Properly, each of those chemical substances are controversial.

Chlorine is a yellow-green gasoline that’s poisonous to people in giant quantities. It’s been used for the reason that 1800s as a disinfectant and deodorizer, sometimes in hospitals, and it was first used to disinfect water in 1897.

Chlorine is exceptionally efficient at killing numerous sorts of micro organism and viruses, together with polio. Sadly, it might additionally kill individuals.

Chlorine was used as a poison gasoline throughout World Warfare 1 by either side, which has tarnished its popularity as a disinfectant ever since.

Naturally, individuals have issues about ingesting a probably toxic chemical.

The chlorine utilized in chemical warfare isn’t the identical because the chlorine used to disinfect ingesting water, although. 

First, a lot of the chlorine added to water throughout remedy is eliminated earlier than it’s pumped to your faucet, and the quantities left over are far too small to be harmful to people. 

Second, the detrimental uncomfortable side effects of chlorine are principally brought on by inhaling concentrated chlorine gasoline, which isn’t the case if you’re ingesting calmly chlorinated water.

Third, you possibly can simply take away the final traces of chlorine out of your ingesting water by utilizing an affordable filter, like a Brita water filter. 

And what about fluoride?

Fluoride is a colorless, tasteless mineral discovered naturally in water, soil, crops, and rocks. It’s additionally discovered naturally in your tooth and bones the place it helps enhance the structural integrity of those tissues.

With out stepping into the politics and ethics of involuntarily giving giant teams of individuals remedy, water fluoridation does appear to cut back tooth decay.

For instance, a evaluation examine carried out by scientists on the College of Manchester discovered that water fluoridation lowered the speed of dental cavities by 35% in child tooth and 26% in everlasting tooth.

Different analysis, although, exhibits water fluoridation won’t be as efficient as many authorities declare. 

For instance, a report carried out by the European Fee discovered that folks can get all the advantages of fluoride from fluoride-containing toothpaste and from the small quantity of fluoride in meals. 

Additionally they discovered areas that ceased including fluoride to the water provide didn’t expertise a rise in dental cavities (indicating fluoride could not have been stopping them within the first place). 

There are additionally dangers to water fluoridation.

If fluoride ranges within the water are too excessive, individuals (particularly youngsters) can develop dental fluorosis. Though that is typically innocent, it does produce white streaks and splotches on the tooth. 

In excessive instances, consuming giant quantities of fluoride over time can result in skeletal fluorosis, which is an accumulation of fluoride in bone. This could trigger bone and joint ache in addition to deformities in essentially the most extreme instances. 

Fortunately, this often solely happens in areas with naturally excessive fluoride ranges within the water or excessive ranges of fluoride air pollution.

Sarcastically, chances are you’ll get much more fluoride from uncooked water than faucet water, relying on the place you reside. For instance, the soil in lots of elements of Africa and Asia naturally comprises extra fluoride than different areas, and other people ingesting uncooked water have developed fluorosis earlier than. 

On the entire, international locations are nonetheless divided about whether or not or not the advantages of water fluoridation are definitely worth the dangers. 

Uncooked water devotees use this lack of consensus to say that uncooked water is healthier for you, however that isn’t the case.

It’s true that uncooked water doesn’t comprise chlorine, and possibly doesn’t comprise fluoride (if it’s gathered within the U.S.), however there are comparatively straightforward methods to take away these chemical substances out of your water with out exposing your self to pathogens and different pollution in uncooked water.

For instance, you possibly can simply take away chlorine with an affordable charcoal filter like a Brita. 

Fluoride molecules are more durable to take away from water, however a reverse-osmosis filter will eliminate them. 

Abstract: Chlorine in water isn’t a significant well being concern, and though the jury remains to be out on the professionals and cons of fluoride, it’s almost certainly benign or mildly useful. 

If you wish to keep away from these two chemical substances, you may also take away them from faucet water with correct filtration strategies.

The Backside Line on Uncooked Water

Uncooked water is water collected from the outside—sometimes from streams or springs—that hasn’t undergone any type of filtration, remedy, or heating to kill pathogens and take away contaminants.

Proponents of uncooked water declare this lack of water remedy is sweet for you.

Treating the water removes the minerals and wholesome micro organism, they are saying. Plus, uncooked water doesn’t comprise any dangerous chlorine or fluoride, like faucet water, they add.

The fact is uncooked water can and often does comprise many micro organism, a few of which is perhaps helpful, however most of that are both benign or dangerous. Uncooked water may comprise many different pathogens similar to viruses, amoebas, and parasites which might trigger an extended checklist of illnesses even in developed international locations. 

Uncooked water additionally comprises extra minerals than faucet or bottled water, however not sufficient to have any influence in your well being. What’s extra, it’s additionally extra prone to comprise heavy metals and different pollution.

Lastly, though most faucet and bottled water comprises chlorine, the quantity is simply too small to have any influence in your well being. You may also simply take away chlorine out of your ingesting water by filtering it with an affordable charcoal filter. 

Though there’s little proof fluoride is dangerous, it’s straightforward sufficient to take away through the use of a reverse-osmosis filter. 

The underside line is that uncooked water is kind of another well being rip-off. 

If I have been you, I’d keep on with the water you’ve gotten now.
