Dairy products do not cause Crohn’s disease, according to new research.
Scientists at the University of East Anglia said there was no link between the consumption of pasteurised milk and the onset of the disease, which causes inflammation of the intestine and deep ulcers.
Experts previously believed Crohn’s was caused by the bacteria Mycobacterium paratuberculosis, which causes a similar disease - Johne’s - in cattle and sheep. They feared it could be expressed in milk and might survive pasteurisation.
The new research will be welcomed by milk processors, who have previously faced calls to increase pasteurisation temperatures in a bid to wipe out MAP.
