This article published by Medical News Today is worth a read. A new case report about a woman with a UTI who became ill from high water intake raises questions about doctors’ advice to ‘drink plenty of fluids.’

I take exception with both the headline and the central argument. Statistically, it fundamentally erroneous to generalize based upon a sample of one or two.
The point that the article misses is that most people in advanced countries do not drink enough water and this causes unnecessary health issues.
Thoughts?

I’m with Dr Alf here because the advice about plenty of fluids holds good and has held good for hundreds of years.
Obviously the word “plenty” means as much as a human being of that size and physique can reasonably ingest at that moment in time so to try and drink more than a liter of water at a time might be too much.
The Japanese knew this in World War 2 when they force fed POW’s with gallons of water until they burst.
So it is a question of knowing how much water is enough and exercising commonsense.
