The paper “Dietary lutein plus zeaxanthin and choline intake is interactively associated with cognitive flexibility in middle-adulthood in adults with overweight and obesity” authored by Caitlyn G Edwards from the University of Illinois at Urbana-Champaign and published in Nutritional Neuroscience explored potential interactive capabilities of these dietary components on cognitive function.

The observational study conducted in 80 middle-aged adults with overweight and obesity collected records of dietary intake, serum levels of these dietary compounds, macular pigment optical density in addition to cognitive assessments. Higher intake of lutein combined with zeaxanthin and choline were associated interactively with faster performance on a cognitive flexibility task. after controlling for pertinent covariates. Additionally, plasma phosphatidylcholine concentrations were associated with higher accuracy in Switch trials, while no other biomarkers were associated with cognitive outcomes.
