Researchers from the University of Eastern Finland found a link between blood metabolite profile associated with lower risk of developing type 2 diabetes and consumption of one egg per day.
In a previous study, the same team of researchers had already associated consuming one egg daily with lower risk of developing type 2 diabetes, in a group of middle-aged men included in Kuopio Ischaemic Heart Disease Risk Factor Study in eastern Finland. Now, the new study was aimed to exploring which compounds may be responsible for this association.
Stefania Noerman, Early Stage Researcher and lead author of the study, said: “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,” says.
The researchers found that the blood samples of men that consumed more eggs contained certain lipid molecules associated to blood profile of men who remained free of type 2 diabetes. Additionally, they found several compounds in blood linked to a higher risk of diabetes, including the amino acid tyrosine.
“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,” Noerman concluded.
