Why a kidney-friendly diet matters

Food first, supplements second

In chronic kidney disease, what you eat and drink every day usually matters more than any single supplement. Potassium, phosphate, sodium, protein and fluid balance are the levers UK renal dietitians work with first — informed by NICE NG203, KDIGO 2024 and KDOQI 2020 nutrition guidance. These guides give you a clinician-reviewed starting point on the specific foods and drinks UK kidney patients ask about most. They are general education and not a replacement for personalised renal-team advice.

Always check significant diet changes with your GP, renal dietitian or nephrologist — especially if you have advanced CKD (Stage 4–5), are on dialysis, have had a kidney transplant, are pregnant or breastfeeding, or take regular medication such as ACE inhibitors, ARBs or potassium-sparing diuretics.
