5 Myths About Drinking Distilled Water

Distilled water is water that has been boiled into vapor and condensed back into liquid, removing impurities in the process. Despite its purity, there are several myths and misconceptions about drinking distilled water. This article aims to address and debunk these myths using scientific evidence and expert opinions.

Background

The debate around drinking distilled water has been ongoing for years, with some proponents claiming health benefits and others warning of potential risks. Much of the controversy stems from a few widely cited publications that have been criticized for their lack of scientific rigor and misinterpretation of data.

Myth 1: Distilled water leaches minerals from the body

One of the most persistent myths is that distilled water, due to its lack of minerals, will “leach” or remove essential minerals from the body.

Debunked: This claim is not supported by scientific evidence. The human body absorbs water through osmosis, which is driven by sodium concentration, not the mineral content of the water. Furthermore, the body has protective mechanisms to prevent mineral loss. Calcium absorption, for example, is a complex process regulated by vitamin D and is not significantly affected by the type of water consumed.

Myth 2: Distilled water is “dead” or lacks “vital energy”

Some claim that the distillation process removes a supposed “vital force” from water, rendering it “dead” or less healthful.

Debunked: This concept has no basis in science. Water molecules are identical whether they come from a distiller, a tap, or a natural spring. Water is an inorganic compound and does not possess any “life force” in a scientific sense.

Myth 3: Drinking distilled water leads to mineral deficiencies

It’s often claimed that drinking distilled water will lead to deficiencies in essential minerals like calcium and magnesium.

Debunked: While it’s true that distilled water lacks minerals, drinking water is not a primary source of these nutrients for most people. The recommended daily intake of calcium (1000-1200 mg) and magnesium (300-400 mg) is primarily obtained from food sources. Even mineral-rich “hard” water typically provides only a small percentage of daily mineral requirements.

Myth 4: Distilled water causes health problems due to its lack of minerals

Some sources claim that populations drinking soft or demineralized water have higher rates of certain health issues, particularly cardiovascular problems.

Debunked: These claims often stem from misinterpretation of studies comparing hard and soft water consumption. It’s important to note that soft water is not the same as distilled water. Moreover, these population studies do not establish causation and may not account for other factors influencing health outcomes.

Myth 5: Distilled water is unsafe for infants

There have been claims that distilled water is dangerous for infants, potentially causing hyponatremia (low blood sodium levels).

Debunked: Cases of water intoxication in infants are typically related to excessive water intake of any type, not specifically distilled water. The danger lies in giving infants too much water or overly diluted formula, regardless of the water source.

Scientific Perspective

From a scientific standpoint, there is no evidence that drinking distilled water is harmful to human health. The human body is well-equipped to maintain its mineral balance through various regulatory mechanisms, primarily relying on dietary sources for mineral intake.

Practical Considerations

While distilled water is safe to drink, there are practical reasons why it might be remineralized in certain contexts:

1. Taste: Distilled water can taste “flat” to some people, and adding minerals can improve its palatability.
2. Large-scale water systems: In desalination plants or municipal water systems, remineralization helps prevent corrosion in pipes and adjusts the water’s pH.
3. Consumer preference: Some consumers prefer the taste of water with some mineral content.

Conclusion

The myths surrounding distilled water consumption largely stem from misunderstandings of human physiology and misinterpretations of scientific studies. While distilled water lacks minerals, there is no scientific evidence to support claims of adverse health effects from its consumption. As with any dietary choice, individuals with specific health concerns should consult with healthcare professionals for personalized advice.
