Western Diet enhances Inflammation - Cell Publication

What effects does diet have on the immune system? Prof. Dr. Eicke Latz and Dr. Anette Christ from the Institute for Innate Immunity of the University of Bonn investigated this question in a study. (c) Photo: Volker Lannert/Uni Bonn

 

The immune system reacts similarly to a high fat and high calorie diet as to a bacterial infection. This is shown by a recent study led by the Cluster member Prof. Dr. Eicke Latz, who is director of the Institute of Innate Immunity Bonn.

Particularly disturbing: Unhealthy food seems to make the body’s defenses more aggressive in the long term. Even long after switching to a healthy diet, inflammation towards innate immune stimulation is more pronounced. These long-term changes may be involved in the development of arteriosclerosis and diabetes, diseases linked to Western diet consumption. The results will be published in the journal ‘Cell’.

“Genomic studies did, in fact, show that the Western diet had activated a large number of genes in the progenitor cells. The genes affected included those responsible for proliferation and maturation“, explains cluster member Prof. Dr. Joachim Schultze from the Life & Medical Sciences Institute (LIMES) and the German Center for Neurodegenerative Diseases (DZNE).
