You can drink 0ppm water for long time without any ill effect, what body will do is it will take required minerals from whatever source available; food veggies etc. or other body parts if levels are critically low.
The point is to supply natural (Not synthetic) minerals to the body at regular intervals.
So yes tap water is OK to drink. RO/DI is OK to drink IF you have enough minerals in perfect proportions, but what we know in this hobby is that, if you don't test it you don't know where you at right?

You are right about what your body will do if you have low serum calcium but wrong about what role ro/di water can play. Sorry. The recommendation is that daily calcium intake be around 1000 mg/day. Our water on the west coast is pretty soft so calcium levels in the Vancouver area average around 1.4 mg/L. Areas with very hard water can be up to around 135 mg/L. Most spring water is around 20 mg/L. Mineral waters are higher and average around 200 mg/L. So to get your full calcium from lower mainland tap water you would have to drink over 700 liters every day. With the best mineral waters and given average water intake you could possibly get 40% of your calcium from drinking water. The majority of our calcium and other minerals come from the food we eat. Average daily intake of water is less than 2 liters. So in the lower mainland you are possibly getting 2 to 3 mg of calcium per day from your drinking water, or 2% of your daily intake. So a 2% reduction from drinking ro/di will make no real difference. If you are getting adequate minerals from your food or vitamin supplements then drinking RO/DI water will not change that. The minerals get absorbed by your body and used. If your diet is low in those minerals you probably won't get enough from drinking water to make up the difference unless you are drinking several liters of mineral water each day. You are better off talking a vitamin supplement etc. if you need it.
The type of water you drink will make no difference whatsoever. You are either getting enough in your diet or not. RO/DI wayter cannot and will not pull minerals from your body. It just isn't possible.
Also, I have seen people argue that ro/di water is acidic and therefor bad for you. While true in relation to regular tap water it is not a big deal. I believe ro/di water can get down to pH 6.0 or so by absorbing atmospheric CO2. However, compare this to stuff like pop or citrus juices and they are more acidic than ro/di water so that argument doesn't hold water either (sorry for the pun).
Anyhow, sorry if I sound confrontational. I just get irked by conclusions based on poor science, pseudo science or or just plain wrong information.
