I cold brew my coffee and not only does it remove most of the acid, but it makes the best tasting coffee ever! I typically drink one very large and strong coffee every morning with a little organic skim milk. I use organic or fair trade beans and brew half caff and half decaff.
I LOVE my coffee.
I think I finally have a handle on my parasite load because I have been rifing for parasites and also doing 30 day cleanses. I hadn't been doing much between the 30 day cleanses and wasn't doing them often enough (maybe once or twice per year)
You have to be persistent. I don't think a little coffee will hurt.
