Dasani, the bottled water from Coca Cola, is not pure water. It proudly declares on the label "Enhanced with minerals for a pure, fresh taste!" But if you read the ingredients, you see that means it includes:

Filtered water, magnesium sulfate, potassium chloride, salt

Yuck! Water is supposed to be tasteless (it certainly shouldn't taste like magnesium sulfate, anyway) so I'm assuming they add those extra ingredients to increase shelf life or something like that.

Does anyone know why those extra ingredients are added to Dasani?

They do it to make you thirstier in order to buy more water.

Remember the tagline: "The water that makes your mouth water."

Uh, no. The mineral content is still FAR lower than that of your normal body fluids; as such, it will not make you thirsty no matter how much you drink.

Pure water -- either distilled or deionized -- tastes terrible. Feel free to buy some and drink it. (If it's really pure, it can't hurt you.) The trace minerals do add noticable flavor.

People generally feel that water should taste like spring water. The most common anions in spring water are calcium, magnesium, patassium, and sodium. The most common cations are sulfate and chloride. There are frequenty small amounts of iron, copper, aluminum, fluorides and nitrates, but these are not considered desirable and add an off taste. It seem like Dasani has the common salts covered except for calcium. Some taste panel probably decided that the water tastes better without calcium.

My understanding is that they use reverse osmosis to purify the water and then add the minerals to it to taste good, but by controlling the amount and type of minerals added, they can ensure a consistent taste. (Basically that's the same process used to make a Coke; start with purified water and then add ingredients in specific quantities so the taste is always the same.)

Many people like the flavor of lightly mineralized water. Not me, personally - I've always thought Dasani tastes weird. But I suppose if some company was able to duplicate the mineral content of my hometown water, I'd think "that's perfect - this is the way water is supposed to taste."

So they can justify charging you $2.00 for a 20 oz. bottle of water ($4.00 if you avail yourself of the minibar in your hotel room).

Yes. Nor is there any chance that it ever will be, at least under that name. The negative publicity was a bit too much. People assume that bottled water comes from a natural spring. They don't want to be sold tap water, least of all tap water that's been treated to add dangerous stuff that wasn't there to start with. The whole thing felt like a scam.

OK, I know it's been said, but ALL water on earth is recycled endlessly-how much (of Julius caeser's urine0, do you get in a bottle of dasani?
Why would spring water be any better than treated river water?
Or take that super-expensive stuff frok Norway (Voss Water)-its from melted glacial ice. How much better is that?

Dasani is just Coke without the syrup and carbonation. You're paying as much or more for bottled tap water as you would for Coke. I'll bet the Coke people spent an entire day high 5ing each other when they found out they could get people to pay that much for tap water.

I think bromate was the problem not salt.

But the entire batch was being withdrawn today after the drink was found to contain levels of bromate - a substance linked with an increased cancer risk - in excess of UK legal standards.


Coca-Cola stressed there was no health risk from drinking bottles of Dasani. A spokeswoman said the decision to recall UK supplies of the drink was voluntary and a precautionary measure.

She said: "In very, very large quantities (bromate) can affect your health but we have been advised by the FSA that the levels of bromate that have been detected in Dasani do not pose an immediate health risk.

Many papers, unhelpfully for Coca-Cola, also reminded readers that while Dasani sells for 95p per 500ml, Thames Water, which supplies homes in the area where the product is sourced and bottled, sells the water at the equivalent of 0.03p per 500ml.

The soft drinks giant claims a "highly sophisticated purification process" removed any impurities, such as "bacteria, viruses, salts, minerals, sugars, proteins and toxin particles" and describes Dasani on the product label as "pure, still water".

But the FSA launched an investigation into the labelling claim after it emerged that Dasani is sourced from mains water.

Distilled water tastes fine to me, and better than a lot of bottled and tap water. It just doesn't quench my thirst as much as slightly mineralized water. It also absorbs all the flavor of its container, so it can taste like rubber if its in a plastic container.

I wonder why you say "yuck" about magnesium sulfate, but not about "minerals". Magnesium sulfate is a mineral. Mineral water is just water with various inorganic salts dissolved in it.

From what I've heard, NYC's tap water is considered the finest in the nation, to the extent that some restaurant owners will ship the tap water to out-of-city franchises for use in their cooking so that the flavor is consistent across different locations. You got some great stuff there, so I don't blame you for snubbing bottles.

Down in my neck of the woods, however, our water has so many minerals that if you leave a sink full of it long enough, it'll form geodes. Here, we need to filter, or drink the bottled stuff.

Fiddle-faddle. Drinking water certainly is not supposed to be tasteless. I have noticed significant differences in the taste of tap water from one place to another.

All I know is that to me Aquafina tastes a hell of a lot better.

I agree. When it comes to cola drinks, I prefer Coca-Cola, but when it comes to bottled water, for some reason I find Aquafina really tasty.

But the point remains that Adirondack water is some seriously tasty stuff. If they bottled it they would outsell the rivals who only claim theirs tastes like a mountain stream: the tapwater in the Saratoga Springs region really does. Somewhat crisply mineral and with just a hint of dirt to suggest streamy freshness.

Is this a whoosh? http://en.wikipedia.org/wiki/Saline_%28medicine%29

Normal saline is a solution of 0.9% w/v of NaCl

If I remember correctly the nutritional label on Dasani says 0mg sodium. Whatever particulates they add are insignificant and for taste only. For instance, this bottle of Japanese "ion supply beverage" claims 21 mEq/l Na+, 5 mEq/l K+, 16.5 mEq/l Cl-, 1 mEq/l Ca2+, and 0.5 mEq/l of Mg2+ (and other stuff). Even on sodium alone that's still almost 6-7 times less than human fluids and this stuff tastes salty.

Now, chemistry I suck at aside, are you a vegetarian? Because I'm fairly sure a medium-rare steak prepared with no salt or pepper is all proof I need that mammalian fluids have significantly more sodium, potassium and magnesium than bottled water by taste alone.

No it's not a whoosh. Just because a steak tastes saltier than bottled water does't tell me whether or not all of Dasani's ingredients are contained in my blood in higher concentration.

06-19-2007, 05:38 PM
I guess I should be more specific and ask:

How much magnesium sulfate and potassium chloride does the blood contain? How much does Dasani water contain?

groman

I guess I should be more specific and ask:

How much magnesium sulfate and potassium chloride does the blood contain? How much does Dasani water contain?

Normal serum levels (from here) (http://www.medicinenet.com/electrolytes/article.htm)
sodium ~ 135 - 145 mmol/l
potassium ~ 3.5 - 5 mmol/l
chloride ~ 98 - 108 mmol/l

(from here) (http://www.med.umich.edu/1libr/aha/aha_smagnesi_crs.htm)

magnesium 98 - 108 mmol/l

And here (http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=1590) you can see a table of magnesium sulfate dose for seizure control. Notice how a 1L single dose IV bag has 40 GRAMS of magnesium sulfate, and that clearly won't instantly kill you.

According to Coca Cola, the amount of minerals in Dasani is a trace amounts added for taste only. If I remember my chemistry and did my math correctly (dopers, please check), the above serum concentrations (take max normal) in mg per liter (which is next to useless in terms of both chemistry and pharmacology but is easier to visualize for most people) are:
sodium ~ 3300mg per liter
potassium ~ 195mg per liter
chlorine ~ 3800mg per liter
magnesium ~ 3800mg per liter

I couldn't find specific information on Dasani, but I promise you it's not nearly that much. I did find this study (warning: PDF) (http://www.datcp.state.wi.us/fs/consumerinfo/food/publications/pdf/bottled_water_FY04.pdf) that gives you more than you ever wanted to know about certain brands of bottled water (Dasani not one of them, as far as I can tell). If you notice, barely any of the waters exceeded 250mg/l of dissolved solids total and the average was 209.1 mg/l. Average amount of chlorides was 17.89mg/l. This article also states that there's an FDA 500mg/l maximum limit on dissolved solids in bottled water. With a 500mg/l total limit the only thing that could exceed your body concentration of in Dasani, is potassium. Now, I can't prove dasani does not have nearly 500mg/l of potassium chloride right now, but I would bet $50 that normally it does not.

Whenever I'm in France the first thing I do is buy a case or so of Vittel water. It's the only bottled water I've ever tasted that seemed to be worth the price. At least, it's worth the price there, but in the States it's brutally expensive, so I revert back to tap. The mineral concentrations, in mg/l are:

Calcium - 91
Magnesium - 19.9
Sodium - 7.3
Potassium - 4.9
Bicarbonate (Hyrd.Carb) - 258
Sulphate - 105
Nitrate - 0.6

I grew up in the Saratoga area, drinkng well water, and I know good water. I also used to enjoy taking people out to the springs for the first taste of mineral water. It is definitely an acquired taste. The mineral springs are around ten times more concentrated than well water, and some of them contain several isotopes of radium. I don't remember when the posted warnings went up, but it was pretty funny to see people's reaction to them.

Distilled water tastes... Well flat and rather boring, not to mention it often ends up tasting like whatever container (often plastic) it was being held in. Water with added minerals tastes noticeably purer to me and it has a better flavor to boot.

Granted, I just got myself a Brita pitcher long ago because I can't stand the tap water here but when I'm out in public, thirsty, and don't want empty calories and sugar, I proudly buy bottled water. So what?

High fructose corn syrup is a sugar. It's broken down by your digestive system before it ever reaches your blood supply. Most salts, including potassium chloride, magnesium sulfate and of course sodium chloride, are not.

I'm sure it was real difficult to discover that. Real muck-raking journalism there. They don't exactly advertise that it is purified tap water but it isn't a secret either.

But I suppose if some company was able to duplicate the mineral content of my hometown water, I'd think "that's perfect - this is the way water is supposed to taste."

Since most of the Auqafina around here is bottled in my old hometown, that is probably why I like it.

I have been a water treatment operator many years, but now work for Coca Cola as a technician. But I will tell you of a case here in Florida of a women who drank water. A women in Orange County Florida checked into a hospital a few years back. She was deathly ill and the doctors were perplexed. They asked all the normal questions like what had she been eating and what she had been drinking. Just regular meals and was proud that she only drank water. No booze, no soda. Her bones had become mushy, her organs were shutting down and the questions kept coming, without any answers as to what has happening to her. She failed to add one small detail about her drinking habits. The doctors all assumed that since she lived in the city, she was drinking city water. Finally, an astute and wise doctor thought to throw the question out there. Any odd colors or tastes to your water? Oh heavens no! she replied. " I only drink pure and distilled water to avoid Fluoride and Chlorine! The problem was that the body NEEDS minerals! When you cut off a sufficient supply, it begins to leach them from wherever it can get them. In this case it was her bones, kidneys and liver. She was saved. A few weeks on an IV and her health returned. SO besides the fact that pure or distilled water tastes like crap, minerals are needed to keep the body going. In order to avoid any lawsuit by some numb skull drinking only Dasani water without minerals and the lawsuits that would surely follow, they remove that possibility by adding minerals BACK into the water during bottle filling. For those concerned, as I am, about fluoride, Dasani has Zero fluoride.

Of course it sounds like complete bullshit, because it is. The person who believes this firstly doesn't know anything about chemistry, because thinking there's significant minerals in drinking water is arrant nonsense, and secondly, doesn't know anything about people, because if you're the kind of crank who drinks nothing but distilled water to avoid chemicals, that's the first thing you tell everyone from your doctor to your dog groomer. There's no way it would take an old and wise doctor to ask the question, everyone in earshot whould have known it.
