Sugary drinks and processed foods may damage immune system, finds study

In simpler words, the study showed 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.

Dr Nick Jones, of Swansea University's Medical School, said: 'Research into different components of our diet can help us understand what might contribute to inflammation and disease and what could be best harnessed to improve health and wellbeing."

Dr Emma Vincent in the Bristol Medical School: Populational Health Sciences (PHS), said: 'Our study is exciting because it takes us a step further towards understanding why some diets can lead to ill health.'

The study titled, "Fructose reprogrammes glutamine-dependent oxidative metabolism to support LPS-induced inflammation," is published in the journal Nature Communications.
