NCT ID NCT05628350

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
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 This study
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 Results may not be published yet.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
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether reducing ultra-processed foods (UPF) can improve blood vessel function in middle-aged adults, a key factor in heart disease. Seventeen participants ate either a diet with no UPF or one with high UPF for six weeks. Researchers measured changes in artery function and looked at gut health as a possible mechanism. This is a small, early-stage trial to gather initial evidence for a larger study.

What this could mean

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

Active substance
controlled diet without ultra-processed foods
What this could lead to
If it works, this could point toward a dietary approach to improve vascular health in middle-aged adults.
What could go wrong
This is a very small, early proof-of-concept study with only 17 participants. Results may not apply to the general population, and the diet is highly controlled, making real-world adoption challenging.
