Masking Details
Patients will be randomized in a 1:1 ratio. Randomization will be performed within the electronic database system at the time of enrollment using a random number generator, an approach we have used successfully in other clinical trials. The participants will be blinded to the intervention assignment (single blinded study).

Intervention Model
CROSSOVER
Model Details: Single-center, randomized, single-blinded cross-over trial including healthy adult participants (N=40, omnivores, aged between 25 and 65 years, and with a body mass index (BMI) between 20 and 40 kg/m2 (see participation criteria below). Following one week of a meat, egg, and seafood free diet ('washout'), participants will be randomized to either red meat (cow burger) or plant meat (plant-based burger) for one week. Following this, participants will under go another week of diet washout and will then be crossed over to the other meat burger for one week. The primary outcome will be the within-group change in the TMAO levels.
