Cured meat consumption and risk of readmission in COPD patients

In plain English

Researchers followed 274 patients hospitalised for the first time with COPD in Barcelona, recording their cured-meat intake (salami, chorizo, ham, bacon) and whether they were later readmitted. Those eating the most cured meat had roughly double the risk of being readmitted for their COPD over the following ~2.6 years. Nitrite preservatives — which generate reactive nitrogen species that inflame airway tissue — are the leading mechanistic suspect.

Why it matters

High cured-meat intake roughly doubled the risk of COPD hospital readmission.

Caveats

A small single-city cohort of people who already had COPD, so it speaks to disease progression, not onset. Cured-meat eaters may differ in smoking and overall diet despite statistical adjustment, and the confidence interval was wide.
