Is it good for you to drink water filtered by RO reverse osmosis membrane for a long time?

No, ro reverse osmosis membrane is actually water with most ions removed, and many trace elements needed by human body cannot be supplemented. If the food intake is insufficient, then the human body will be in a sub-health state because of the lack of trace elements, and even unable to maintain the osmotic pressure of cells, so it is easy to get edema and get sick. It is best to drink water or boil some water. Don't drink pure water all the time.
