[Influence of the lutein-rich products consumption on its supply in diet of individuals with age-related macular degeneration (AMD)].

PURPOSE

The aim of the study was analysis of the influence of the lutein-rich products consumption on its supply in diet of individuals with age-related macular degeneration

MATERIALS AND METHODS

The object of conducted analysis were 127 nutrition questionnaires from 64 individuals with AMD (44 female, 20 male) and 63 without AMD--control group (49 female, 14 male). The age of participants was 50-88. The nutrition questionnaire concerned: AMD and its course, consumption of lutein-rich products and lutein supplementation. Lutein supply was assessed on the base of most often consumed products and lutein content in typical servings as well as on the base of applied supplementation.

RESULTS

Patients with AMD, in comparison with control group, were significantly more often choosing green bean, parsley, dill (Anethum graveolens) and young beetroot leaves, as well as were consuming more diversified lutein-rich products. Lutein supply from diet was significanly increased in case of spinach consumption (very high in lutein) and broccoli consumption (high in lutein and chosen relatively often). Other products did not cause increase of lutein supply from diet, even if they evoked increase of lutein content in the typical serving or of quantity of servings.

CONCLUSIONS

Patients with AMD, in comparison with healthy individuals, more often consume lutein-rich products, but lutein supply from diet in both groups do not differ. Significant increase of lutein supply may be achieved only by consumption of products characterized by the highest content of it. Patients with AMD, in comparison with healthy individuals, more often apply lutein supplementation, that influences lutein daily supply.
