Researchers at Columbia University found a link between Bacon and other cured meats and incidences of Lung Disease.
Dr Rui Jiang, leading the research, said high levels of nitrites are used in cured meats such as bacon as preservatives, anti-bacterial agents and colour fixatives.
He said reactive nitrogen species, molecules that can damage body tissues, might be the key.
He said: “Nitrites generate reactive nitrogen species that may cause damage to the lungs, producing structural changes resembling emphysema.”
