Can kidney patients eat tomatoes?

Tomatoes are moderate in potassium (237 mg/100g). In early CKD, enjoy freely. In stages 3-5 and dialysis, limit raw tomatoes (½ medium daily) and count them in your potassium budget. Cooking for gravies uses small amounts — acceptable. Avoid tomato ketchup (concentrated + sodium) and tomato juice.

Is tomato soup safe for kidney patients?

Tomato soup is concentrated tomato — higher potassium per serving and often high in sodium. For advanced CKD, avoid canned/tetra-pack tomato soups (sodium concern). Homemade soup with 1 small tomato, low salt, split across servings is more acceptable.

Tomatoes are moderately high in potassium (237 mg/100g) — about 290 mg per medium tomato. Raw tomatoes in salads should be limited in CKD stages 3-5 and dialysis. However, most Indian cooking uses tomatoes in small quantities (gravy base), which is generally acceptable. Tomato puree and ketchup are concentrated and higher in potassium and sodium — avoid ketchup.
