More potassium from food helps lower blood pressure when your kidneys handle potassium normally.

**The number:** Adults should get at least 3,510 mg of potassium a day ([WHO, 2013](https://www.who.int/news/item/31-01-2013-who-issues-new-guidance-on-dietary-salt-and-potassium))

## The evidence

- Evidence grade: A. Grade A: meta-analyses of randomised trials, or a major guideline consensus.
- Basis: WHO guideline plus a meta analysis of 22 randomized trials (n=1,606) and 11 cohorts (n=127,038)
- Outcome: adult dietary potassium intake, WHO minimum where appropriate
- Comparison: WHO population guidance, excluding impaired potassium excretion
- Impact: 60/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Potassium works against the effect of sodium on blood pressure. In trials pooled for WHO, higher potassium intake lowered systolic blood pressure by about 3.5 mmHg, an effect seen in people with raised blood pressure rather than in people whose pressure was already normal. The same review linked higher intake with 24% lower stroke risk in cohort studies, which is an association rather than a proven effect.

## How to do it

1. Build meals around beans, peas and lentils, among the richest food sources.
2. Add vegetables such as spinach, cabbage and parsley, and fruit such as bananas.
3. Choose less processed versions of staples, since processing reduces potassium in many foods.
4. Get potassium from food rather than supplements unless a clinician advises otherwise.

## Talk to a clinician first

Kidney disease, or medicines that raise potassium such as ACE inhibitors, ARBs and potassium sparing diuretics, make extra potassium unsafe without clinical advice.

## Putting it into practice

### Start now

- 1 minute: Prepare this question: 'Do my kidneys or medicines mean I should limit potassium?' Keep it for your pharmacist or clinician.
- 5 minutes: Check your medicine list and any kidney diet instructions; if unsure about potassium, request a pharmacist or clinician review.
- 15 minutes: Review yesterday's meals for beans, lentils, vegetables and fruit. If you have kidney disease or relevant medicines, discuss changes before increasing potassium.
- 30 minutes: If extra potassium is suitable, plan three meals using beans, potatoes or vegetables; otherwise, prepare a food record for your renal dietitian.

### What it looks like

- If extra potassium is suitable for you, include cooked beans in a vegetable soup.
- If you have no potassium restriction, try a baked potato with a suitable topping.
- Bring a list of your medicines to a pharmacist before using a potassium salt substitute.

### Common mistakes

- Do not raise potassium on your own with kidney disease or relevant medicines: check with your clinician.
- Do not use potassium tablets or salt substitutes as a food shortcut: ask for advice first.

### A structured start

**Check safety, then use food**

1. Stage 1: Check restrictions and medicines with your clinical team if kidney disease or potassium concerns apply.
2. Stage 2: If suitable, add one food source to a familiar meal without supplements or salt substitutes.
3. Stage 3: Build variety across meals, staying within any individualized dietary advice.
