Study: Even Healthy People Get Blood Sugar Spikes
By Serena GordonHealthDay Reporter TUESDAY, July 24, 2018 (HealthDay News) —
The study also found that certain foods were more likely to prompt an extreme change in blood sugar (glucose) than others.
“Even if you don’t have diabetes, you may not have normal glucose. There are a lot of people with glucose dysfunction out there who don’t know it,” said the study’s lead author, Michael Snyder. He’s director of genomics and personalized medicine at Stanford University School of Medicine, in California.
Snyder said this finding is potentially concerning because spikes in blood sugar levels have been associated with risk of heart attack and stroke. And it’s possible — though it hasn’t been proven in this study — that people who have big rises in their blood sugar after eating may have a higher risk of diabetes.
Type 2 diabetes is a major health problem, affecting more than 30 million U.S. adults and 422 million worldwide, the authors noted.
But not every medical expert is convinced that these changes in blood sugar in healthy people are something to be concerned about.
In addition to discovering the three different glucose spiking patterns, the researchers conducted a sub-study with 30 volunteers who wore a continuous glucose monitor while they ate standardized meals. One meal was cornflakes with milk, another was a protein bar and the third was a peanut butter sandwich.
“Certain foods tend to spike nearly everybody,” Snyder said, adding that the cereal was one such food. About 4 out of 5 people saw their blood sugar jump after consuming cereal and milk, the researchers said.
Some of the spikes observed in the study reached prediabetic and diabetic levels, the study authors noted.
Zonszein said that while continuous glucose monitors are great tools for people with diabetes, they don’t necessarily capture someone’s “glucose metabolism.”
And he doesn’t see the devices being used to replace current screening tests for diabetes until much more research is done comparing this technology to current tests.
