Food entertainment of circadian rhythms
Dr Lalita Oparija
The daily rhythms of sleep, wakefulness, physical activity and eating (circadian rhythms) are coupled to good health. Such rhythms can be set and entrained by light (central clock) or by timed food intake (influencing digestive system rhythms and peripheral clocks). Rhythm disruption by irregular meals, changes in diet, shift work or travel between time zones negatively impacts the functions of various organs and thus our overall health. Despite the importance of circadian rhythms, inadequate knowledge of the baseline circadian rhythmicity in peripheral tissues, the communication pathways for rhythm synchronization, and the potential sex differences holds back understanding of basic mechanisms relevant to health and its disruption.
In this study you will investigate how changed feeding times disrupts circadian rhythms and the expression of nutrient transporters and nutrient handling.
