Fact check: Is distilled water poisonous?

1. Summary of the results

The scientific consensus shows that distilled water is not poisonous in the conventional sense ^{[1] [2]}. Multiple sources confirm its safety for consumption when part of a balanced diet ^{[3] [4]}. However, its long-term exclusive consumption could potentially lead to health concerns, primarily due to mineral deficiencies rather than any inherent toxicity ^[3].

2. Missing context/alternative viewpoints

Several important nuances are worth considering:

• While pure, distilled water receives a "C+" rating due to mixed benefits and disadvantages ^[5]
• There is a theoretical risk identified by German research regarding cell damage due to mineral imbalance, but this risk is neutralized in practice as the water becomes mineralized in the digestive system ^[6]
• The water's lack of minerals is a key consideration that's often overlooked in simple safety discussions ^[1]
• The taste is notably flat compared to mineral water ^[2]
• Healthcare professional consultation is recommended when making distilled water a regular part of one's diet ^[3]

3. Potential misinformation/bias in the original statement

The question "Is distilled water poisonous?" represents an oversimplification of a complex topic. This oversimplification potentially benefits:

• Water purification companies: Who might benefit from either promoting or disparaging distilled water depending on their product lineup
• Mineral water companies: Who benefit from emphasizing the importance of naturally occurring minerals in water
• Health supplement companies: Who could benefit from concerns about mineral deficiencies ^{[3] [4]}

The reality is more nuanced: while distilled water isn't poisonous, its health implications depend entirely on how it's consumed within the context of an overall diet ^{[3] [4] [3]}.
