Correct answer: E — Dietary potassium restriction should be individualised; plant-based potassium sources may be less harmful than processed food additives; a more liberal approach to fruit and vegetables is encouraged

KDIGO 2024 takes a nuanced approach to dietary potassium. Rather than blanket restriction, it recommends individualised assessment. Emerging evidence suggests that potassium from plant-based sources (fruits, vegetables) may be less harmful than potassium from processed foods (potassium additives) due to the alkalinising effect of plant-based foods. A more liberal approach to fruit and vegetable intake is encouraged where possible, with monitoring. Severe restriction may deprive patients of the cardiovascular and metabolic benefits of a plant-rich diet.
