- A person's risk of premature death - increased risk of all-cause mortality - increased with the amount of processed meat eaten.
- Men and women who ate the most processed meat ate the fewest fruit and vegetables and were more likely to smoke.
- Men who ate a lot of meat also tended to have high alcohol consumption.
- People who ate a lot of processed meat were also more likely to be obese, smoke, or make other lifestyle choices that can have a negative effect on health. Even accounting for diet, smoking, physical activity, and body mass index, processed meat was shown to have a major impact on health.

"Risks of dying earlier from cancer and cardiovascular disease also increased with the amount of processed meat eaten, says analysis leader Sabine Rohrmann. Overall, we estimate that three percent of premature deaths each year could be prevented if people ate less than 20 grams of processed meat per day."
The results of our analysis support a moderate positive association between processed meat consumption and mortality in particular due to cardiovascular diseases, but also cancer, the studys authors concluded.
