What foods to eat to prevent gfr?

To help prevent a decline in glomerular filtration rate (GFR) and support kidney health, focus on a diet rich in fruits and vegetables, whole grains, and lean proteins. Foods high in antioxidants, such as berries and leafy greens, can be beneficial. Additionally, limit sodium intake and reduce consumption of processed foods, as well as avoid excessive protein and phosphorus, which can strain the kidneys. Staying hydrated is also essential for maintaining kidney function.
