I was diagnosed with Stage 4 CKD in 2018 due to severe oxylate damage (GFR of 15). Since then, I’ve increased my hydration to 3L a day and gone on a low oxylate diet. I’ve used the below list as a guide. I’m now at Stage 3B (GFR 40), hoping to reach 3A. I’ve found sunflower seeds and macadamia nuts/milk are the only seeds or nuts I can safely consume. Hope this helps. https://kidneystones.uchicago.edu/how-to-eat-a-low-oxalate-diet/
