Study finds link between processed meats and higher risk of cardiovascular disease


TORONTO – A global study conducted by researchers in Hamilton, Ontario. discovered a link between processed meats and an increase in cardiovascular disease and death.
The study, published Wednesday in The American Journal of Clinical Nutrition, found that consuming more than 150 grams of processed meat per week was associated with a 46% higher risk of cardiovascular disease and a 51% higher risk of death. higher than those who did not eat processed meat at all.

To come to this conclusion, the research team – which included a group from McMaster University – tracked the diets and health outcomes of more than 134,000 people in 21 countries for 9.5 years using the Prospective Urban Rural Epidemiology (PURE) study, a questionnaire-based study. research project.

A total of 195 people who ate at least 150 grams of processed meat per week died of cardiovascular problems during the study period, compared with 80 people who ate no processed meat at all.

Meanwhile, 104 people who avoided processed meat developed major cardiovascular disease, compared to 613 people who ate more than 150 grams of processed meat per week.

Conversely, researchers found no association between unprocessed red meat or poultry and cardiovascular disease.

“The totality of the available data indicates that consuming a modest amount of unprocessed meat as part of a healthy diet is unlikely to be harmful,” said Mahshid Dehghan, a researcher at the Population Health Research Institute ( PHRI) from McMaster University, in a press release.

The researchers note that the results were fairly consistent across the countries involved in the research, meaning other factors are less likely to play a role in the results.

“The consistency of the results in different regions with markedly different lifestyles and intakes of unprocessed red meat and poultry makes it less likely that confounding factors, which could have varied in different regions, explain our observations”, have- they wrote in the study.

That said, the researchers added that more study should be undertaken to understand whether the way the meats are prepared plays a role in the results and whether the foods people eat in place of processed meats are also a factor. of their overall health.

“Another limitation was that we couldn’t include the cooking method for each country,” the researchers wrote in the study. “We recognize that this limitation may lessen the association between unprocessed red meat and poultry and the health effects.”
