Lutein May Help Improve Memory Function In Overweight People


People who are overweight or obese tend to have higher levels of chronic inflammation. Previous studies suggest that inflammation may have a negative effect the hippocampus, the area of the brain that plays an important role in memory. A new study has found that lutein may help improve memory function in overweight and obese adults, due to its antioxidant and anti-inflammatory properties.





Ninety-four adults between the ages of 25 and 45 who were overweight or obese participated in the study. The participants completed a 7-day diet record to document their regular carotenoid intake. Serum carotenoid levels were measured via high-performance liquid chromatography. Macular carotenoid levels were also evaluated. The researchers administered a spatial reconstruction task to assess hippocampal-dependent relational memory ability. 





The researchers found that higher serum levels of lutein were positively associated with better relational memory performance on the spatial reconstruction task. No association was found between macular carotenoid levels and relational memory performance.





The study was conducted by researchers from the University of Illinois. It was published April 2, 2019 in the journal Nutrients
