Foods For Good Kidney Health
Introduction of Kidney Health:
If you have kidney disease, you may need to adopt a specific nutritional plan to preserve kidney health as much as possible. A renal diet typically limits sodium, phosphorus, and potassium consumption. This regimen cannot heal your kidneys but may support their capacity.
When the kidneys fail to function properly, waste, including toxic substances from food, accumulates in the blood. Individuals with kidney illness can benefit from a tailored renal diet that regulates certain nutrients.
In this blog, we explore 20 of the finest nutrition foods for kidney health that specialists commend as parts of a kidney-friendly diet.
How Diet Impacts Kidney Disease or Kidney Health?
The dietary limits depend on the level of kidney damage. Those with later-stage kidney disease have different restrictions than those with early-stage disease. At any stage, the diet should boost kidney function while lowering the risk of further damage.
While individual needs vary, those with kidney health disease often need to limit:
- Sodium – below 2gs per day
- Potassium – limits depend on the stage of the disease
- Phosphorus – 800-1000 mg per day
- Protein – limits depend on the stage of disease
Since kidney disease and heart disease are closely connected, combine these diet choices with a heart-healthy diet focused on fresh, whole foods low in saturated fats.
Consult a doctor to discuss your individual dietary needs for your stage of kidney disease.
