The debate over whether eggs are good or bad for you seems to be unending, but here's a new study that scores one for the pro-egg team.
Researchers at the University of Eastern Finland have found that the consumption of one egg a day relates to a blood metabolite profile that is associated with a lower risk for type 2 diabetes, reports MedicalXpress.com.
The study follows up on a previous study that also showed a positive relationship between consuming eggs and lower risk of type 2 diabetes, but took it one step further to identify exactly what's going on when an egg is metabolized in the body that's so beneficial.
"The purpose of the current study was to explore potential compounds that could explain this association using non-targeted metabolomics, a technique that enables a broad profiling of chemicals in a sample," explained the lead author of the study, Stefania Noerman.
The key components in eggs that gives them their diabetes-crushing power appears to be certain lipid molecules that positively correlate with the blood profile of men in the study who avoided developing the disease. Interestingly, by carrying out these blood profiles, researchers were also able to identify several biochemical compounds in blood that do predict a higher risk of developing type 2 diabetes. So the research will be a boon to our understanding of this condition beyond just the effect that egg consumption has on it.
Don't go on an egg splurge just yet
There are some important caveats to keep in mind before gorging on eggs for their health benefits, however. For one, this study looked strictly at egg consumption in moderation, i.e., study subjects consumed just one egg a day. Moderation, as with most things, is likely important for achieving the desired health benefits. Furthermore, there are other studies which flag eggs for their ill effects on health as well. For instance, eggs are extremely high in cholesterol.
Doctors often recommend cutting down on egg consumption for patients with heart health concerns, for this very reason. So it's best to understand the results of this new study as just part of the overall health profile of egg consumption. They aren't all-good or all-bad; they have benefits, they have detriments. Nutrition and health are complicated, so take these new pro-egg studies with a grain of salt (another metaphor that advises dietary moderation!)
"Although it is too early to draw any causal conclusions, we now have some hints about certain egg-related compounds that may have a role in type 2 diabetes development. Further detailed investigations with both cell models and intervention studies in humans that use modern techniques, such as metabolomics, are needed to understand the mechanisms behind physiological effects of egg intake," concluded Noerman.
