@csage10 Welcome to Mayo Clinic Connect, an online community of caring people who share their experiences in hopes of easing anothers' health journey!

As @kamama94 has said, everyone is different. She mentioned the Davita Kidney website, and here is a link for you to look at https://www.davita.com/diet-nutrition It's never too early [or late] to eat well for your health situation. You can have that control and help advocate for yourself.

With your existing conditions of pre-diabetes and hypertension, has your dr ever told you these are the top two causes of kidney disease? They are! As you read through the many discussions here on kidney issues, you can tailor the information to your own case, even if you haven't seen the nephrologist, yet. He/she will hopefully be happy to hear you are proactive in your case, and know they are dealing with an informed patient.
