Values adjusted by the residual method. MDA: malondialdehyde; PCn: protein carbonyl; CHO: carbohydrate; GPx: glutathione peroxidase; TAC: total antioxidant capacity; npAC: nonprotein antioxidant capacity. values in bold indicate significant correlation of MDA and PCn with nutrient intake and plasmatic antioxidants ().
