Drrinking rainwater

by Paul

Hi, I live off grid in a remote part of Spain & harvest rainwater from the roof & upstairs terrace that is then stored in underground tanks.

It's then pumped to a header tank through a particle filter & into the house through another particle filter. I then use a locally made filter which slowly takes it through sand, granite, carbon & a volcanic material.

I have a TDS (total dissolved solids) meter which typically reads 70 mg/l before & 84 after.

The taste is rather flat & not that pleasant but OK. I want to add celtic sea salt to it but am unsure of how much. Can you help please?

My health condition makes it so important that I rehydrate more than normal as I have no colon but an ileal anal reservoir or J Pouch. Thank you in advance & sorry for the long post


Hi Paul, the amount of Celtic sea salt that is recommended by Dr. Batmanghelidj, author of "Your Body's Many Cries for Water" is as follows:

1. On a daily basis, drink half your body weight in ounces of water. If you weigh 200 pounds, you would drink 100 ounces of water (about 3 quarts).

2. For every 16 ounces of water, take 1/8 teaspoon of natural salt. You could add it directly to the water. However, it is best to put the salt directly on your tongue and let it dissolve in your mouth before you drink the water. When dissolved in your mouth, the salt will quickly enter your bloodstream and will attract the water into your cells.

However, drinking enough water is the key. Adding too much salt without enough water may have an adverse effect. In fact, I found that 1/8 teaspoon of salt is too much for me. I just add a pinch of salt on my tongue per quart of water. So each person's needs are going to be different.
