Abstract
The present study investigated the interrelationships between the concentration of total polyphenols (TP), malondialdehyde (MDA), total antioxidant capacity (TAC), lactate dehydrogenase activity (LDH) and content of toxic elements (Al, As, Cd, Ni, Pb) in human colostrum milk (n = 75), and further assessed their potential association with maternal lifestyle characteristics. As and Cd were always below detection limits while Al, Ni and Pb were found at the level of 89.7, 6.2 and 1.3 μg L−1, respectively. Concentrations of TP and MDA, in the studied group were 46.91 ± 21.25 mg GAE L−1 and 0.66 ± 0.27 nmol mL−1, respectively, and were inversely correlated (Rs = −0.32; p < 0.01). TP and TAC increased significantly with maternal consumption of vegetables (Rs = 0.25 and Rs = 0.37, respectively; p < 0.05). Concentration of Al was positively correlated with MDA (Rs = 0.21; p < 0.01) and negatively with TP (Rs = −0.28; p < 0.01). Positive correlation was also found between Pb and MDA (Rs = 0.32; p < 0.01). No association with place of living (urban/rural), women's age and former smoking were found for any studied milk parameter. The results add to the general understanding of factors influencing redox balance in milk and potentially affecting its quality.
