meaning of study on lard vs vegetable oil in oxidative stress

here is the study http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2901759/

the conclusion reads:In summary, peripheral blood phagocytes produced less ROS in rats fed high-lard and plasma of these animals had lower ability to decompose DPPH radicals than rats fed high-SO. The erythrocyte glutathione redox status was the highest in rats fed the diet containing lard, and the lowest in rats fed SO. These findings indicate that a diet high in linoleic acid-rich sunflower oil causes a greater phagocyte oxidative burst than ingestion the same energy from saturated fatty acids and marine origin n-3 PUFA, augments oxidative stress in erythrocytes, and can lead to tissue microinjury. However, total antioxidant plasma ability in rats fed sunflower oil was higher than in rats fed equal energy from other fats.

it says :"diet high in linoleic acid-rich sunflower oil causes a greater phagocyte oxidative burst than ingestion the same energy from saturated fatty acids"

any thoughts?

Meh, it causes a greater oxidative burst but also has higher antioxidant levels in plasma. The body really is an amazing thing.
