@nscappa Here is a link to an article from Fresenius Kidney Care, about coffee, potassium and our enjoyment of it. I personally do not do black coffee, but do use a non-dairy creamer and artificial sweetner. Hey, it's one cup a day, so I am going to enjoy it, dang it!
As for why your eGFR level dropped, it could be any number of reason. You were not feeling well, perhaps you were on antibiotics? We need to look at trends, not always a one-time thing. And frankly, as our kidney disease progresses, we have to accept that the numbers indicating a lower eGFR may be here to stay. It sounds like you are watching your diet closely, and reading food labels have to be part of that. Meals don't have to be boring, spicing them up with spices can be a great thing and fun to try!
I will be interested to hear what your nephrologist has to say when you have that appointment.

Ginger,
Thank you for the link to the coffee article. There are so many conflicting articles regarding the consumption of coffee and it's impact on the kidneys. I talked to a dietician that specializes in nephrology nutrition. She stated that drinking a cup a day is fine. It is important to drink water or Crystal Light with the cup of java as coffee is dehydrating.
If you do drink coffee, be sure to brew it. Instant coffee is not good for the kidney.
There is one part of the article that I don't agree with. It suggests drinking tea. Everything I've read advises you not drink brewed tea. I would steer clear of tea.
