Abstract
RESULTS: Mean lutein ± SD intake from food was 0.87 ± 0.76 mg/1,000 kcal at baseline. Mean MPOD, best corrected visual acuity, and serum lutein concentrations were increased at 1 and 2 months compared with baseline.
CONCLUSION: Constant intake of lutein-rich spinach increased both MPOD and serum lutein concentrations. These data are important for planning of a future interventional study examining the effects of dietary lutein.
PURPOSE: Anti-oxidative nutrient supplements, including lutein, are an important preventive approach for age-related macular degeneration (AMD). In this pilot study, we obtained data required for planning a future dietary intervention study investigating the prevention of AMD progression with lutein-rich spinach.
METHODS: We examined 22 eyes from 11 healthy nonsmokers (ages 21-45 years) who ingested 75 g of frozen spinach containing 10 mg lutein every day for 2 months. Food frequency questionnaire, measurement of macular pigment optical density (MPOD), and eye and blood examinations were performed.
