The absence of minerals and contaminants in distilled water ensures that it does not interfere with chemical reactions or compromise the integrity of medical procedures.
4. Reduces Risk Of Kidney Stones
For individuals prone to kidney stones, distilled water may offer some benefits. The lack of dissolved minerals, such as calcium and magnesium, means that distilled water does not contribute to the accumulation of these substances in the body. This can be particularly beneficial for those who have a history of kidney stones or who are at risk of developing them, as it may help reduce the likelihood of stone formation.
5. Prevents Scale Build-Up in Appliances
The absence of minerals in distilled water means that it does not leave behind scale or mineral deposits when used in appliances such as steam irons, humidifiers, or coffee makers. This can extend the lifespan of these appliances and improve their efficiency, as scale build-up can reduce heat transfer and cause mechanical issues over time. Using distilled water in these appliances also eliminates the need for frequent descaling and maintenance, saving time and effort.
6. Safe For Use In Infant Formula
Distilled water is often recommended for mixing infant formula, particularly in areas where the tap water may not be safe for consumption. The purity of distilled water ensures that it does not introduce any harmful substances or contaminants into the formula, making it a safer option for infants. Additionally, distilled water does not contain fluoride, which, while beneficial for dental health, can be harmful to infants in excessive amounts.
7. Effective For Detoxification
Some proponents of distilled water argue that it can aid in detoxification by helping to remove toxins and impurities from the body. The idea is that, because distilled water is free from dissolved substances, it can more effectively flush out waste products and toxins. While scientific evidence supporting this claim is limited, many people who undergo detox programs prefer distilled water for its perceived ability to support the body’s natural cleansing processes.
8. No Added Sodium
Unlike some bottled waters that may contain added sodium for taste or as a preservative, distilled water is free from sodium. This makes it an excellent choice for individuals on a low-sodium diet or those with conditions such as hypertension, where sodium intake needs to be carefully monitored. By choosing distilled water, consumers can avoid unintentional sodium consumption and better control their overall dietary intake.
9. Neutral Taste
Distilled water has a neutral taste, as it lacks the minerals and impurities that can affect the flavor of tap or spring water. This can be an advantage for individuals who prefer a clean, unaltered taste in their drinking water or for use in cooking and beverages where the flavor of the water can influence the final product. The neutrality of distilled water makes it a versatile option for a variety of culinary applications.
Cons Of Distilled Water
1. Lacks Essential Minerals
One of the primary disadvantages of distilled water is that it lacks essential minerals such as calcium, magnesium, and potassium, which are naturally present in most other types of drinking water. These minerals contribute to overall health by supporting bone density, cardiovascular function, and electrolyte balance. Regular consumption of distilled water, without compensating for the loss of these minerals through diet or supplements, could potentially lead to mineral deficiencies over time.
2. Potential For Acidic pH
Distilled water can have a slightly acidic pH, especially after exposure to air, where it absorbs carbon dioxide. This slight acidity may not be a concern for most people, but for individuals with sensitive digestive systems or certain health conditions, consuming water with an acidic pH might cause discomfort or exacerbate symptoms. Some users may prefer water with a neutral or slightly alkaline pH to avoid these potential issues.
3. May Leach Minerals From The Body
There is some concern that because distilled water is devoid of minerals, it may leach minerals from the body when consumed regularly. The theory is that distilled water, being “hungry” for minerals, can pull essential minerals from the body’s tissues, potentially leading to deficiencies. While scientific evidence on this claim is not definitive, it is a point of consideration for those who rely on distilled water as their primary source of hydration.
4. Flat Taste
The lack of minerals in distilled water can result in a flat or bland taste that some people find unappealing. Minerals like calcium and magnesium contribute to the flavor profile of natural water, and their absence in distilled water can make it taste less refreshing or satisfying. For individuals who are accustomed to the taste of spring or mineral water, switching to distilled water may require an adjustment period.
5. Environmental Impact Of Distillation Process
The distillation process used to produce distilled water is energy-intensive, as it requires heating water to its boiling point and then cooling it to condense the steam. This process consumes more energy than other water purification methods, such as filtration or reverse osmosis. The environmental impact of this energy consumption, particularly if the energy is derived from non-renewable sources, can be a concern for environmentally conscious consumers.
6. Cost
Distilled water is generally more expensive than tap water and even some bottled waters, particularly when purchased in large quantities or used regularly for drinking. The cost of producing distilled water, combined with the packaging and transportation expenses, can add up over time, making it a less economical option for daily consumption compared to other water sources.
7. Inconvenience Of Regular Purchase Or Production
For those who choose to drink distilled water regularly, the need to purchase or produce it can be inconvenient. Bottled distilled water must be bought from stores, which can be cumbersome and add to the cost. Alternatively, investing in a home distillation unit requires an initial investment and ongoing maintenance, which may not be practical for everyone. This inconvenience can be a significant drawback for individuals seeking a hassle-free hydration option.
8. Not Ideal For Cooking
While distilled water is pure and free from contaminants, it is not always the best choice for cooking. The lack of minerals can affect the taste and texture of certain foods, particularly those that rely on mineral content for flavor or chemical reactions, such as baking bread or brewing coffee. In some cases, using distilled water in cooking can result in less flavorful or inconsistent results compared to using mineral-rich water.
9. Limited Availability In Emergencies
In emergency situations, such as natural disasters or power outages, distilled water may not be readily available. The reliance on a distillation process or bottled supply means that access to distilled water can be limited when regular water sources are disrupted. This limitation makes distilled water less practical as a sole source of hydration in emergency preparedness plans, where accessibility and storage are critical considerations.
