Benefits of Eggs in Combination With a Plant-based Diet

Clinical Trial ID: NCT04234334

Description

The main objective of the study is to demonstrate that the inclusion of eggs to a plant-based diet will not increase the risk for heart disease but will increase the concentration of lutein and zeaxanthin, two important antioxidants and will also increase choline, an important component of membrane phospholipids.

Results from studies involving cells, animal models and clinical trials have demonstrated that lutein and zeaxanthin potentially protect against chronic diseases, including age-related macular degeneration, cataracts, coronary heart disease and stroke. Plasma concentrations of lutein and zeaxanthin are closely associated with their antioxidant properties and with their protection against reactive oxygen species (ROS). Choline is recognized as an essential nutrient for health because of its many functions in growth and development, as well as neurological function and formation of membrane phospholipids, including phosphatidylcholine (PC) and sphingomyelin. Therefore the objective of this study is to demonstrate that inclusion of eggs in a plant-based diet will potentiate the benefits of this healthy diet by increasing plasma concentrations of lutein, zexanthin and choline presents in egg yolks and theoretically increase the antioxidant and anti-inflammatory actions of these components. This would be potentially more important in those individuals with metabolic syndrome, which is the target population of this intervention.
