Cardiovascular disease (CVD) is a global illness causing 31% of global mortality. Though many factors contribute to CVD, oxidative stress advances atherosclerosis through several complementary components, such as the initiation of lipid peroxidation by iron. Blood donation may decrease the risk of CVD due to reducing the iron level. Literature reported that blood donors have a lower risk of CVD, possibly due to the lower iron levels. Various effects of blood donation are involved in preventing type II diabetes. However, little is known of the exact mechanism of the benefits of blood donation. In this study, samples were collected from 33 healthy male participants pre- (1 day) and post-donation (1 day, 1, 2 and 3 weeks) and the effect of the blood donation on the iron, lipids and enzymatic antioxidants profiles were assessed. A repeated-measures ANOVA was used for comparing the quantitative variables between the visits. We found that the iron decreased significantly by week 1 (–25.3%). Ferritin decreased significantly at weeks 1, 2, and 3 (–26.3%, − 40.3%, − 36.7%, respectively). The superoxide dismutase increased significantly at post-donation day 1, weeks 1, 2, and 3 (17.9%,35.7%, 31.1%, 36.6%, respectively) and in correlation with time [r (165) = 0.50, P r (165) = 0.3, P |
