I can not speak in medical terms but I can describe my own experience. I am 76 and have had mild diabetes and mild high blood pressure for a number of years. In March 2024 my EGFR registered at 34. Panic set in and I was sent to a nephrologist who cut my hydrochlorothiazide dose in half and referred me to a dietician. I had previously been on a diet that leaned towards keto, heavy on meat, probably a BIG mistake. I was then placed on a mainly plant based diet. No restrictions on corn or potatoes. Moderate amounts of protein. My EGFR has improved over the past year: June 2024-55, November 2024-59, April 2025-65.

I have not cut out cheese/milk/eggs/fish completely but limit portions and frequency. I no longer even have a taste for beef (never ate pork). Will rarely eat a small piece of chicken. Lots of beans, fruits, vegetables and tofu as well. Try to keep sodium down to reasonable amounts. I have my fingers crossed that the improvement will continue.
