**5. Conclusions**

In our study, we observed significant increases in the levels of several crucial endogenous antioxidants in blood samples from patients with AMD, which further suggests that the necessary balance of the antioxidant system is disrupted during the disease course. Since dietary habits potentially modulate AMD progression by contributing to the antioxidant status, we also investigated food intake in our cohort and identified several significant correlations. Based on our results, a diet rich in green vegetables, eggs, fish and omega-3-rich oils, accompanied by physical activity, is beneficial for patients with AMD and might slow disease progression and help maintain better visual functions. Further studies of larger cohorts might elucidate the potential effects of various other food components and nutritional factors on the severity and progression of AMD or even their roles in preventing this disease.
