Overview
- Italy’s latest reports restate, rather than update, the 2015 IARC decision that processed meats, including cooked ham, are Group 1 carcinogens.
- IARC’s review of more than 800 studies found an association with colorectal cancer, estimating about an 18% higher risk per 50 grams of processed meat consumed daily.
- The IARC grouping reflects the strength of evidence in humans and does not quantify an individual’s absolute risk, which remains relatively small compared with hazards like tobacco.
- Scientists point to processing methods and preservatives such as nitrites and nitrates that can form carcinogenic nitrosamines, with some experts advising ample vegetables alongside cured meats.
- Guidance highlighted in the coverage urges keeping processed meats to occasional use, observing limits such as roughly 50 g per week for processed meat and 500 g per week for red meat, within a Mediterranean-style diet and regular exercise.
