High fructose diets could cause immune system damage

Parent Interventions

New research led by Swansea University in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in the sugar fructose might prevent the proper functioning of peoples' immune systems in ways that has, until now, largely been unknown.

Fructose is commonly found in sugary drinks, sweets and processed foods and is used widely in food production. It is associated with obesity, type 2 diabetes and non-alcoholic fatty liver disease and its intake has increased substantially throughout the developed world in recent years. However, understanding the impact of fructose on the immune system of people who consume it in high levels, has been limited until now.

The new study published on 22 February in the journal Nature Communications shows that fructose causes the immune system to become inflamed and that process produces more reactive molecules which are associated with inflammation. Inflammation of this kind can go on to damage cells and tissues and contribute to organs and body systems not working as they should and could lead to disease. The research also brings a deeper understanding about how fructose could be linked to diabetes and obesity - as low- level inflammation is often associated with obesity. It also builds on the growing body of evidence available to public health policy makers about the damaging effects of consuming high levels of fructose.
