Habit, Food clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Innovations Applied to the Pyrenean Beef Production to Enhance Consumer-identifiable Meat.

DIETAPYR2

Start date: January 20, 2019
Phase: N/A
Study type: Interventional

The DIETAPYR2 study is a randomized controlled crossover trial consisting of two experimental periods each lasting 8 weeks. Enrolled participants were randomly assigned to either a Pyrenean beef-based diet or a conventional chicken-based diet and instructed to consume this meat three times a week. In the first visit the medical history was obtained and anthropometric measurements, blood pressure (systolic and diastolic) and heart rate were taken. The day after the first visit, in the morning, a sample of blood, stool and urine was taken from the participants after an overnight fast. At the time of this visit (period 1), each participant was randomly assigned to a Pyrenean beef diet (intervention group) or a conventional chicken-based diet (control group). After an experimental period of 8 weeks, the participants were invited to carry out the same evaluations as during the first visit. Subsequently, a 5-week washout period was carried out to eliminate the possible residual effects of the first experimental period. After the washout period, the participants were called back for the same assessments during a third visit just before the second experimental period (period 2). During this period, those who were previously on a Pyrenean beef diet (intervention group) were crossed with the conventional chicken diet (control group) and vice versa. Finally, after the second 8-week experimental period, the participants were retested as on previous visits.
