Hi Raven999 and glad to meet you!
I imagine your head is still spinning with all the changes in your life, glad to be alive but perhaps angry at all the change.
I'm a 61 year old female too whose hubby started dialysis one year ago, and I've spent half the year learning about Phosphorus as a result.
I put together a little website about what I learned that might be useful to you:
https://mylowphosdiet.wordpress.com/the-protein-to-phosphorus-ratio/ . One thing I learned about cereals is that
Crispix and
Special K have about half as much phosphorus as
Rice Krispies (I was amazed).
Best wishes as you navigate these new waters!
