Each week we will aim to bring out a concise email that provides 4-5 key pieces of information addressing a specific issue in clinical therapeutics.
This week: Potassium Rich Foods
Natalie Soulsby, Head of Clinical Development, Ward MM
With the shortage of slow release potassium expected to continue until the end of this year, potential alternatives include increasing the amount of potassium that is in the diet.
- Please note that these high potassium containing foods should not be used to treat hypokalaemia. Hypokalaemia caused by diuretics or vomiting may not respond to increased dietary intake due to chloride depletion. This is because most potassium in food is present as the phosphate salt and not the chloride salt.
- The average daily requirement for potassium is 120mmol/day in the healthy population, however in the elderly and those on medications that can increase serum potassium (e.g. ACEI, ARBs, NSAIDs or potassium sparing diuretics) they will need less than this. Caution needs to be exercised in those people with reduced renal function as they may already have elevated serum potassium levels.
- Below is a table of some foods that are high in potassium and their mmol equivalents.
- One slow release potassium tablet is equivalent to 8 mmol of potassium.
