What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This study will test whether the way food is processed affects health, even when the diet is equally healthy. 330 adults will eat either a high or low ultra-processed plant-based diet for 4 months. Researchers will measure changes in blood sugar and cholesterol to see if processing alone makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
dietary intervention (high vs low ultra-processed foods, both healthy plant-based)
What this could lead to
If it works, this could clarify whether the processing of food—not just its nutritional content—matters for heart health and blood sugar.
What could go wrong
This is a small, early-stage dietary study with no disease treatment. Results may not apply to the general population, and diet adherence can be challenging.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 330 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Oct 2026

An estimate. Start dates often move.

Expected to finish

Jun 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Men and women aged between 18 and 65 years in general good health with BMI \< 35 kg/m2 who can provide informed consent. Exclusion Criteria: * Participants will be ineligible to enrol if they have diabetes, CVD, any type of cancer (except for basal cell skin cancer), or a condition (pregnancy, breastfeeding, etc) or dietary restriction(s) that would substantially limit their ability to complete the study. Individuals will be screened for their adherence to the Plant based diet Index (PDI ). 1. Individuals with low adherence will enter run-in phase only (6 weeks) 2. Individuals with high adherence will enter the main intervention (4 months)
