Working nights? Lay off the spinach and liver.

Science Daily has more dietary recommendations for resetting your body’s clock:

Disrupted circadian clocks, researchers believe, are the reason that shift workers experience higher incidents of type 2 diabetes, obesity and cancer. The body’s primary circadian clock, which regulates sleep and eating, is in the brain. But other body tissues also have circadian clocks, including the liver, which regulates blood glucose levels.

In a new study in Diabetes online, University of Utah researchers show that dietary iron plays an important role in the circadian clock of the liver. Judith A. Simcox, Ph.D., a University of Utah postdoctoral fellow in biochemistry, is the study’s lead author.

“Iron is like the dial that sets the timing of the clock,” Simcox says. “Discovering a factor, such as iron, that sets the circadian rhythm of the liver may have broad implications for people who do shift work.”
