In the present study, lutein content of vegetables and vegetable products, fruits as well as eggs available on the Polish market was estimated with the use of high performance liquid chromatography (HPLC). The highest concentration of lutein was found in green leafy vegetables: spinach (8.95 mg/100 g), cabbage Savoy (6.89 mg/100 g), lettuce (1.65 mg/100 g), celery leaves (1.68 mg/100 g) as well as in yellow and green vegetables: pumpkin (2.82 mg/100 g), zucchini (1.14 mg/100 g), broccoli (1.97 mg/100 g), and green peas (2.23 mg/100 g), whereas its lowest concentration was observed in fruits ( 0.60 mg/100 g). The mean content of lutein in eggs was found to reach 0.62 mg/100 g and depend on the method of breeding. The average estimated intake of lutein was 1.78 mg/person/day, the main source of this carotenoid being vegetables and vegetable products (70.8 percent), potatoes (12.3 percent), eggs (10.1 percent), and fruits (5.9 percent)
