Can kidney patients eat rajma (kidney beans)?

With caution. Kidney beans are high in potassium (367 mg/100g) and canned rajma adds sodium (275 mg). Early CKD: small portions of home-cooked dried beans. Advanced CKD/dialysis: avoid or strictly limit — moong dal is the lighter legume choice.

Does soaking beans reduce potassium?

Soaking and discarding the water, then cooking in fresh water, reduces some potassium and sodium — but not enough to make high-potassium beans 'safe' in advanced CKD. Portion control remains the main lever.

Kidney beans are high in potassium (367 mg per 100g) and canned versions carry significant sodium (275 mg). Half a cup adds ~480 mg potassium — a large share of the daily budget in advanced CKD. If used, choose dried beans soaked and cooked at home (lower sodium) and keep portions small; avoid in stages 4-5 and dialysis.
