A diet high in saturated fat is a key contributor to type 2 diabetes, a major health threat worldwide. Several decades ago scientists noticed that people with type 2 diabetes have overly active immune responses, leaving their bodies rife with inflammatory chemicals.

In addition, people who acquire the disease are typically obese and are resistant to insulin, the hormone that removes sugar from the blood and stores it as energy.

Now, researchers from the University of North Carolina at Chapel Hill School of Medicine found that saturated fatty acids but not the unsaturated type can activate immune cells to produce an inflammatory protein, called interleukin-1beta.

"The cellular path that mediates fatty acid metabolism is also the one that causes interleukin-1beta production," said senior study co-author Jenny Y. Ting, William Kenan Rand Professor in the Department of Microbiology and Immunology.

"Interleukin-1beta then acts on tissues and organs such as the liver, muscle and fat (adipose) to turn off their response to insulin, making them insulin resistant. As a result, activation of this pathway by fatty acid can lead to insulin resistance and type 2 diabetes symptoms," added Ting.

The study has been published in the journal Nature Immunology.
