### Serum Free Fatty Acid, Selenium, Vitamin E, and Lutein Concentrations  
The concentration of n-6 PUFAs (eicosadienoic acid, gamma-linolenic acid, dihomo-gamma-linolenic acid) in serum decreased after the consumption of Nutri4 eggs, whereas the concentration of n-3 PUFAs (eicosa-5,8,11,14,17-pentaenoic acid) increased. In addition, a favorable decrease in the n6/n3 PUFA ratio was observed in the Nutri4 group after the consumption of enriched eggs (Table 2). The levels of C14:0 myristic acid and C18:0 stearic acid also decreased in the Nutri4 group after the consumption of eggs. In the control group, serum fatty acid levels were not significantly changed following the dietary protocol. \begin{table}
