Potassium is in more than bananas
Bananas are a well-known source, but potatoes, beans, lentils, spinach, tomatoes, yoghurt, milk and salmon can also contribute. You have plenty of options if bananas are not your thing.
The way a food is prepared changes the final dish. A baked potato with its skin, beans in a sauce and a packet of salted crisps are not nutritionally interchangeable just because they begin with potato.
Build it into a balanced meal
Try a jacket potato with beans and salad, lentil soup with wholemeal bread, or yoghurt with fruit and oats. These combinations offer potassium alongside fibre, protein or calcium.
Fruit and vegetables can be fresh, frozen or tinned. The option you can afford, store and use is usually the most helpful one.
Check before increasing potassium for medical reasons
People with kidney disease or those taking certain medicines may need to limit potassium. Do not follow a high-potassium plan without checking with your clinician if this might apply to you.
A food database gives an estimate. Clinical blood results and personal medical advice are what matter when potassium is part of treatment.
Questions people ask
Are bananas the best source of potassium?
They are useful, but not uniquely high. Potatoes, pulses, vegetables, dairy and fish can all make a meaningful contribution.
Should I take a potassium supplement?
Only with medical advice. Potassium supplements are not appropriate for everyone, especially people with kidney or heart conditions.
