Foods with over ~250-350 mg potassium per 100 g — the foods that push blood potassium toward dangerous levels in advanced CKD.
High-potassium foods include dates (~696 mg/100 g), raisins, bananas, potatoes, avocado, spinach, and most nuts and dried fruits. In stages 3b-5 and dialysis, these are avoided or strictly portion-controlled. The threshold matters: foods above 350 mg/100 g are 'avoid' in this database; 200-350 mg are 'caution'. Portion size multiplies the risk — a handful of dates can exceed the entire daily potassium budget.
Potassium obtained from food and drink — the main modifiable driver of blood potassium levels in kidney disease.
High potassium in the blood — a common and potentially dangerous complication of CKD, especially with ACEi/ARB therapy — causing heart rhythm disturbances at severe levels.
The eating plan for dialysis patients - higher protein (1.2 g/kg/day) with tight potassium, phosphorus, sodium, and fluid control.
