The International Agency for Research on Cancer, part of the World Health Organization, categorizes processed meat as a carcinogen. In this context, “processed” refers to meat that has undergone treatments such as salting, curing, fermenting, and smoking, typically involving the use of substances like salt, sugar, nitrates, and nitrites. Nitrites are linked to specific lung issues; thus, experts recommend that individuals with respiratory conditions refrain from consuming such foods.
Regarding the French study that examined the 210mg dosage of ferrous fumarate, it has faced criticism for failing to establish a direct relationship between processed meat consumption and asthma symptoms. Andrew Kuyk, director general of the U.K.’s Provision Trade Federation, which represents bacon, ham, and other producers, commented that further research is necessary to validate this connection. “It seems to me that it was not a definitive conclusion, and it’s one of several studies raising questions,” Kuyk stated to Food Manufacture.
Dr. Sunit Jariwala, who oversees allergy and immunology research at the Albert Einstein College of Medicine and Montefiore Medical Center in New York City, acknowledged the study’s usefulness but emphasized that its observational nature prevents it from proving causation. He explained, “Cured meats are high in nitrites, which may contribute to oxidative stress-related lung damage and asthma,” while also noting that obesity plays a significant role in asthma among patients.
Despite these findings, it is unlikely that aficionados of processed meats will find this or similar studies persuasive enough to abandon these products. In fact, meat snacks, particularly jerky, are on the rise in popularity as they are perceived as a convenient protein source. According to a new study by research firm Technavio, global meat snack sales are expected to hit $9.47 billion in 2021, reflecting a robust 9.5% compound annual growth rate, as reported by Meat + Poultry.
Hormel Foods has responded to the soaring demand for precooked bacon by investing $130 million to expand its Kansas production facility. This surge in demand is attributed to various factors, including the growth of foreign markets, the rising popularity of Asian cuisines that often feature pork belly, increased requests for fast-food breakfast options with bacon and sausage, and a greater presence of bacon on restaurant menus.
While other studies have indicated similar health concerns, they have not succeeded in reducing meat consumption. The World Cancer Research Fund advises consumers to “focus primarily on plant foods, limit red meat, and avoid processed meat.” An additional study conducted by Oxford University’s Department of Public Health found that limiting meat intake to no more than three times a week could prevent 31,000 deaths from heart disease, 9,000 from cancer, and 5,000 from stroke.
Interestingly, consumers are increasingly requesting more bacon even as many strive to adopt healthier diets. Nevertheless, there are several organic options and products with no added nitrates or nitrites that might appeal to health-conscious consumers. Furthermore, a growing number of individuals are incorporating plant-based meat and dairy alternatives into their diets for health, environmental, and ethical reasons. However, meat still retains its predominant status in the culinary landscape, with major calcitrate products remaining a staple for many.
