Fact check: How much distilled water can you safely drink?

1. Summary of the results

Distilled water is fundamentally safe to drink ^{[1] [2] [3]}, but comes with important caveats. It is the purest form of water but lacks essential minerals like calcium, magnesium, sodium, and copper that are normally found in tap water ^{[2] [4]}. The scientific consensus shows that drinking distilled water is acceptable as part of a balanced diet ^{[4] [5]}, but should not be your primary or sole source of hydration ^[5].

2. Missing context/alternative viewpoints

Several crucial points are missing from the original question:

• Molecular Instability: Distilled water is molecularly unstable ^[4], which has implications for long-term consumption.
• Mineral Loss Through Sweat: There's a specific concern about mineral deficiencies, particularly for minerals lost through sweat ^[6].
• Long-term Effects: While occasional consumption is safe, extended use as a primary water source could lead to:
• Nutrient deficiencies ^[6]
• Electrolyte imbalances ^[4]
• General mineral deficiencies ^[7]

3. Potential misinformation/bias in the original statement

The question itself is oversimplified and could lead to dangerous conclusions. Here's why:

• The question implies there's a simple quantity-based answer, when in reality, safety depends on:
• Overall diet composition ^{[1] [1]}
• Duration of consumption ^[7]
• Individual health conditions ^[6]

It's worth noting that medical professionals should be consulted for personalized advice ^[6], and the Dietary Guidelines do not recommend one water type over another ^[6]. This suggests that water companies marketing distilled water as superior might be overselling its benefits, while mineral water companies might overstate the risks of distilled water consumption.
