LOL. Been to Nepal twice and despite eating this every meal (nearly flavorless rice & lentil soup), can't say it had any side effects. The water situation in Nepal is dire, take a heavy filter with you, but if the food wasn't purchased on the street or wasn't an unwashed fruit, you're likely fine.
Most travelers are diligent about avoiding direct contamination from local water or even ice. Fewer consider the indirect contamination that can occur from a glass washed in tap-water without detergent, or knives used to cut fruit that are washed off in the local water.
I brush my teeth with bottled water, as well.
I spent over a month backpacking around the Annapurna region of Nepal without a filter drinking from both stream and well water without treatment the entire time I was there. Never had a problem. If you are referring to water in / around a village you could say water of every country is dire since that water is almost always contaminated somehow. The water coming straight off a mountain is almost always perfectly fine in my experience which is the case anywhere you go. I'll also add I spoke with several people who also went without a filter and drank from both village wells and streams without any issues. Matter of fact I know of no one who got sick in Nepal. I also ate tons of street food and dhal baht from some of the most hole in the wall places, no issues. As always your mileage may vary but I think calling the situation dire is a stretch.
