Chrononutrition marries the study of circadian biology and nutrition. It is a rapidly evolving field of research, with many interesting papers coming out in the last few years alone. Our internal biological clock can hugely impact upon our nutrition. However, nothing will fuck with your internal biological clock like some good old-fashioned shiftwork. Having done my fair amount of shiftwork (and currently typing this from a 20 hour shift!), I thought it would be interesting to compare the recommendations from the research against my own reality.
