A sausage a day is too many, says Swiss study

A study by the Institute of Social and Preventive Medicine at the University of Zurich says that more than 40 grams (1.4 ounces) of processed meat is hazardous to your health.

“We estimate that three per cent of all premature deaths can be attributed to the high consumption of processed meat,” says Sabine Rohrmann in a release.

Teaming up with research colleagues from 10 countries, she has been studying the link between the consumption of processed meat and the risk of mortality as part of a Europe-wide study with around 450,000 participants.

The release says people who eat a lot of processed meat such as sausage products, salami or ham run a higher risk of dying from cardiovascular disease or cancer. The problem is that carcinogenic substances such as nitrosamines form through salting, pickling or smoking, and these might be the cause of the increase in cancer mortality.

However, processed meats are also rich in cholesterol and saturated fats, which are linked to an increased risk of cardiovascular disease.

Other lifestyle and dietary factors influence the link between the consumption of processed meat and the risk of illness or mortality: for instance, vegetarians often live more healthily than non-vegetarians, do more sports and are less likely to smoke.

Also, the study participants who eat the most processed meat also eat fewer fruit and vegetables, consume more alcohol and smoke more. But even taking these factors into account in the evaluation of the data, the core result of the study still proves to be true: People who eat over 40 grams of processed meat per day have an increased risk of mortality compared to those who eat fewer than 20 grams a day, the release says.

However, meat also is a key source of important vitamins, especially B vitamins, and minerals such as iron.

“Therefore, the moderate consumption of up to 40 grams a day doesn’t increase the mortality risk,” says Rohrmann in the release.
