What this trial studies
The COPLANT study is a multicenter cohort investigation that will recruit approximately 6,000 participants aged 18 to 69 in Germany and Austria from 2024 to 2027. It aims to explore the health benefits and risks associated with various plant-based diets, including vegan, vegetarian, pescetarian, and omnivorous diets, while also assessing social, ecological, and economic impacts. Participants will undergo detailed dietary assessments using a specialized app, alongside measurements of body composition, cardiovascular risk factors, and other health indicators. The study will also focus on specific population groups such as pregnant women and children, ensuring a comprehensive understanding of dietary impacts across different demographics.
Who should consider this trial
Good fit: Ideal candidates for this study are individuals aged 18 to 69 who have been following their current diet for at least one year.
Not a fit: Patients who are unable to provide informed consent or those who are not health insured may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide valuable insights into the health impacts of plant-based diets, potentially guiding dietary recommendations for better health outcomes.
How similar studies have performed: Other studies have shown varying degrees of success in examining the health effects of plant-based diets, making this study a valuable addition to existing research.
