On a good day, I remember what RDA is.belewfripp wrote: ↑Sun Apr 11, 2021 4:17 pm... A guy my age has an RDA of 1000 mg of calcium daily, and while I'd have to drink a lot of high-calcium tea to get up where I was when I was chewing on 10-12 antacid tablets/day, I tend to err on the side of caution since being thirsty all the time (basically the body is trying to wash out the extra calcium) is no fun.
And my ultimate goal, I think, is to be able to judge each tea as best I can - in other words, that if I don't like it it's because I actually don't like the tea, rather than because I am using wildly unsuitable water or teaware; and likewise, to avoid missing out of teas I would like as a result of the same variables. .
More importantly, we learn that one could eat too much calcium & it could lead to thirst & need flushing out of one's body. What used to see happen frequently to so many people was that they took antacids for relief which unfortunately was temporary because the antacids stimulated acid production which required those people to take more antacids. The vicious cycle became less common when word of this got around, even to my ignorant hometown (Phillipsburg, New Jersey) and my overeating, antacid-gobbling family. However, it is so easy for such news to get drowned out by all the commercials for antacids. I suggest drinking hot water, cool water, or carbonated water & avoiding antacids unless on an airplane etc.
Anyway, sounds like you know how to keep your mind occupied. You might have very high standards for what you drink. Very good tea for me will still be good when prepared in "wrong" teaware; & all of my leaves are steeped in the same water (tap water filtered by sterasyl ceramic cylinders with charcoal inside).
If you decide to RO-filter at home, it would be interesting to read about your research into the various systems, especially if it is a small below the sink or countertop system. I think (i.e., do not really know, all RO water is not the same with a range from almost the same as distilled water to water that is mildly filtered).
