I have experienced high BP during a water fast that lowers when I resume eating.
I just bought my second water distiller. There was a catalog with it that listed four different water filters. With a list of 29 possible water contamanants. The carbon filter type did not remove 19 of the 29. The Waterwise distiller with a carbon filter removed all of them. Yes this information was from a distiller company, just FYI.
Reading up on sarcoidosis Diet plays a role. Meat and dairy should be avoided.
