Dialysis patients may get to eat fruits again: new diet focuses on hidden potassium
NCT ID NCT06120608
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests a new diet for people on hemodialysis who have high potassium levels. Instead of cutting out all high-potassium foods like fruits and vegetables, the diet focuses on avoiding foods with potassium that is easily absorbed, such as additives, processed meats, milk, and fruit juices. The study will see if this approach is practical and helps control potassium levels over 3 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dietary approach (restricting high-bioavailability potassium foods)
- What this could lead to
- If it works, this could offer a more flexible diet for dialysis patients to manage potassium levels without giving up fruits and vegetables.
- What could go wrong
- This is a small pilot study with only 50 participants, so results may not apply to everyone. The diet change may be hard to follow or may not lower potassium enough.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * ≥18 years or older * Receiving hemodialysis 3 times/week for ≥ 3 months * Has at least two pre-dialysis serum potassium levels ≥5.2 mmol/L on any analysis in the past 3 months OR the most recent pre-dialysis serum potassium value ≥ 4.6 mmol/L and is currently prescribed a potassium-binding agent at a regular frequency (defined as ≥ once per week). * Can speak and understand French or English * Has not missed more than 1 dialysis session in the previous 3 months. * Is capable of providing informed consent. Exclusion Criteria: * Is not expected to survive beyond 6 months * Does not control their dietary intake (e.g., residents of high-dependency nursing homes) * Significant cognitive impairment precluding understanding of the dietary recommendations.
