Processed meats preserved with sodium nitrite may cause cancer, research suggests.

The World Cancer Research Fund recommends eating “very little, if any, processed meat because there is strong evidence it is a cause of bowel cancer”.

Whether hot dogs, bacon or sausages, processed meat is defined as an animal product that has been salted, cured, fermented or smoked to enhance its flavour and prolong its shelf life.

While all processed meats were once tarred with the “cancer brush”, scientists from Queen’s University Belfast argue only those preserved with sodium nitrite carry a risk.
