Mineral rich water, magnesium, soaking issues...

[Guest guest]

Hello,

We use reverse osmosis water in order to limit contaminants (such as

heavy metals, and other stuff) in our food. How can you get clean

mineral rich water if you filter it first? I saw some dicussion in a

couple of posts regarding magnesium and other beneficial contents in

water but I can't see how to get water with the right mineral content

if I have to filter it first. Could I rely on bone broth prepared

with the reverse osmosis water to get the minerals such as magnesium?

Also, when I soak nuts am I soaking out magnesium and then throwing it

away in the water? When I soak grain I don't drain the liquid off the

grain before using the grain so am I consuming phytates or are the

phytates broken won completely and the minerals released? Which

brings me to another question. Why would you drain soak water from

beans but not from grains? And... how can you confirm that your food

is even a good source of magnesium to begin with. Can I use a brix

meter?
