Abstract
Background. Carotenoids and docosahexaenoic acid (DHA) were identified as essential components for eye health and are both naturally present in eggs. Objective. We aimed to evaluate the effect of the daily consumption of two eggs enriched with lutein/zeaxanthin and DHA on macular pigment optical density (MPOD) and on circulating xanthophyll and fatty acid concentrations in healthy participants. Methods. Ninety-nine healthy volunteers consumed either two standard eggs or two enriched eggs per day for 4 months. MPOD was measured at baseline (V0) and at follow-up (V4) using a modified confocal scanning laser ophthalmoscope (primary outcome). Blood samples were collected to determine total plasma and lipoprotein fatty acids and lutein/zeaxanthin compositions at V0 and V4 (secondary outcomes). Results. A slight but significant increase in MPOD was observed for all study participants consuming two eggs per day for 4 months at all eccentricities (0.5°, 1°, 2°, and 4°). Plasma and lipoprotein lutein, zeaxanthin, and DHA concentrations significantly increased in both groups but were greater in the enriched group (for the enriched group (V0 vs. V4): lutein, 167 vs. 369 ng/mL; zeaxanthin, 17.7 vs. 29.2 ng/mL; DHA, 1.89 vs. 2.56% of total fatty acids). Interestingly, lutein from high-density lipoprotein (HDL) was strongly correlated with MPOD at 0.5 and 1° eccentricities (rho = 0.385, p = 0.008, and rho = 0.461, p = 0.001, respectively). Conclusions. MPOD was slightly increased in both groups. Lutein, zeaxanthin, and DHA plasma concentrations were strongly enhanced in the enriched group compared with the standard group. A significant correlation was found between MPOD level and lutein concentration in HDL.

Abstract
A aterosclerose, principal responsável pela patogênese do infarto miocárdico e cerebral, bem como pela gangrena e por outras doenças vasculares periféricas, permanece como principal causa de morbidade e mortalidade nas populações "ocidentalizadas". Estima-se que 17,5 milhões de pessoas morreram por doenças cardiovasculares em 2005, o que representou 30% das causas de morte nesse ano, e que, em 2015, 20 milhões de pessoas morrerão por doenças cardiovasculares no mundo. Os ácidos graxos n-3, principalmente os de cadeia longa, encontrados nos peixes, têm-se mostrado particularmente úteis na prevenção e tratamento de doenças como dislipidemias, diabetes mellitus e obesidade, apresentando importante efeito cardioprotetor. Nesse contexto, pesquisas têm evidenciado que ao menos parte dos benefícios dos ácidos graxos eicosapentaenóico e docosahexaenóico sobre o risco de doenças cardiovasculares é decorrente da modulação de genes responsivos aos receptores ativados por proliferadores de peroxissomos e envolvidos no metabolismo lipídico. Nesta revisão, pretende-se expor alguns mecanismos de ação dos ácidos graxos n-3 e n-6 sobre o metabolismo de lipídeos e de lipoproteínas. Conclui-se que muitos aspectos que contribuem para o risco de doenças cardiovasculares são afetados pela ingestão de n-3. Além da redução de triglicérides, fatores como o aumento de adiponectina, a redução da concentração de colesterol plasmático e a melhora do transporte reverso de colesterol também são responsáveis pela redução do risco de aterosclerose promovida pelos ácidos graxos n-3. No entanto, ainda são necessários estudos adicionais para definir mais claramente os mecanismos celulares e moleculares responsáveis pelo efeito cardioprotetor dos ácidos graxos n-3.
