Study finds daytime meals may reduce health risks linked to night shift work

Study finds daytime meals may reduce health risks linked to night shift work

Credit: CC0 Public Domain A small clinical trial supported by the National Institutes of Health has found that eating during the nighttime—like many shift workers do—can increase glucose levels, while eating only during the daytime might prevent the higher glucose levels now linked with a nocturnal work life. The findings, the study authors said, could …
