This study is testing a new way to understand how your diet affects your gut bacteria (microbiota). Researchers are using a small, swallowable device called a "mini-pill" to collect samples from different parts of your digestive system. You would eat either plant-based meat alternative entrees or meat-based entrees. The main goal is to see if these mini-pills can successfully show changes in your gut bacteria after eating these different diets over 8 weeks. To join, you should be between 50 and 75 years old, a man or postmenopausal woman, and have normal digestive, kidney, and liver function. You also need to be willing to swallow the mini-pills and collect stool samples. The study's status is currently unclear.

Study design

This is a randomized-controlled double-blind crossover trial with a planned enrollment of 30 participants. It involves two phases where participants will switch between diets.

What's involved

You would consume provided meals (either meat or plant-based meat alternatives) for up to 3 weeks in each phase. After 2 weeks on each diet, you would swallow 6 mini-pills and collect stool samples until all mini-pills are recovered, which can take 2 to 6 days.

Compensation

Not stated in the trial record.

Follow-up

The primary goal is measured at 8 weeks, indicating follow-up for at least that duration.
