| Outline of Final Research Achievements |
Present study was to examine acute effects of monounsaturated and saturated dietary fats on diurnal variation in energy metabolism and core body temperature, and sleep in human. Ten young male subjects consumed the high monounsaturated fatty acid meal (high oleic acid) or high saturated fatty acid meal (high palmitic acid). Compared with meal rich in saturated fatty acid, consumption of high monounsaturated fatty acid meal induced the followings; 1) Fat oxidation was significantly enhanced over 24 hours, 2) Core body temperature was lowered in the evening and the first half of the sleep (from 19:00 to 2:00), 3) Slow wave sleep was significantly increased in first sleep cycle. It raised the possibility that the ingestion of different fatty acids may affect all of these parameters of biological rhythm. High intake of saturated fatty acids may be a risk factor of obesity through circadian derangement and inhibit fat oxidation.
