Eating foods rich in lutein regularly may help to improve cardio-metabolic health.

This study assessed the effect of high dietary ingestion and blood levels of lutein on cardio-metabolic health using a meta-analytic approach. Data from 71 scientific publications were included in this meta-analysis. 

Researchers discovered that consistent consumption of lutein-containing foods and elevated plasma concentrations of lutein are associated with not only enhanced cardio-metabolic health but also diminished risk of having cardio-metabolic diseases, such as atherosclerosis and metabolic syndrome. This meta-analysis provides evidence that a high lutein diet may have a positive effect on cardio-metabolic health.
