Effects of interactions between various fats and active/passive phases on postprandial inflammation in rats
(Taylor & Francis Ltd, 2016) Otlu, H. Gul; Kayhan, Basak; Guldur, Tayfun
The circadian clock controls number of behavioral and physiological processes during daily light/dark cycle including inflammation and vascular injury. However, how reciprocal interaction of dietary fats and light/dark cycle affects postprandial inflammation is currently unknown. To this end, effects of various dietary fats given to rats by gavaging either in light or dark phase on postprandial inflammation were compared. Sunflower oil load activated greater number of inflammatory CD markers in passive phase whereas the butter load in active phase compared to their counter phase. The inflammatory influence of fish oil load appeared to be mostly confined to passive phase. Differences found between the levels of some of the inflammatory markers in active and passive phases of normal fed rats were altered by fat/oil administrations. We conclude that influences of dietary fats/oils on postprandial inflammatory changes might depend not only on their fatty acid compositions but also on their ingestion times.
