Are Fresh Tomatoes High in Potassium

Fresh tomatoes contain a decent amount of potassium (one medium tomato has 292 mg, per USDA data), and you’ll get even more bang for your buck from more concentrated forms of tomatoes, such as tomato paste (162 mg per tablespoon) or tomato sauce (728 mg per cup).

Can I eat tomatoes on a low potassium diet?

People with chronic kidney disease (CKD) are often concerned about eating tomatoes if they have been advised by their renal dietitian to follow a low potassium diet. However, in the right amount and served with the right foods, tomatoes can still be enjoyed safely.

How do you remove potassium from tomatoes?

Blanching your vegetables in boiling water for 1 minute before using in cooking will also help reduce the potassium content. If making a tomato-based sauce, use less tomato than you usually would. Use tinned tomatoes rather than tomato paste, puree or passata.
