I have always assumed a test after eating certain foods at a set time would be fairly consistent on blood glucose levels, eating 2 boiled eggs at 10am would have the same effect as eating them at 10pm

But I usually eat at all different times but have not really thought that the same food could cause different levels at different times of the day.
Don't know if it does Just seems like another variable to take into account and mess up some of the test conclusions!
I also worked nights for 6 years and this is the 1st I have heard any association with diabetes


Body Clock, Blood Sugar Control Seem Linked

Oct. 9 (HealthDay News) -- A strong link exists between the body's biological clock and blood sugar control, say U.S. researchers who conducted lab experiments on mouse and human stem cells, as well as genetically engineered mice.

"The most surprising part of our findings is that our internal biologic rhythms are embedded directly into another pathway, one that is essential to regulate metabolism," senior author Dr. Brian Feldman, an assistant professor of pediatric endocrinology at the Stanford University School of Medicine, said in a university news release.

The researchers found that daily fluctuations in hormones called glucocorticoids synchronize the biological clock as part of the mechanism for regulating blood sugar levels. The finding may help lead to new ways to control diabetics' blood sugar levels and may improve understanding of why night-shift workers are at risk for obesity and diabetes.

The research may also help find ways to reduce the disabling side effects of glucocorticoid drugs such as prednisone, an immune system-suppressing medication used to treat severe asthma, cancer and other conditions. Side effects include weight gain, poor blood sugar regulation and diabetes.
