The iconic American hotdog, a staple of the nation’s food culture, has come under scrutiny in recent years due to its association with various diseases. Emerging evidence suggests that processed meats, such as bacon, sausage, and salami, may contribute to the development of leading health conditions. Studies have shown that a reduction in processed meat intake, even by as little as 30 percent, could have significant public health benefits, including the prevention of type 2 diabetes, cardiovascular disease, colorectal cancer, and overall mortality.
Compared to unprocessed red meat, like ground beef or sirloin, processed meat has been more clearly linked to an increased risk of cardiovascular disease, type 2 diabetes, and certain types of cancer, such as colorectal cancer. While there is still a lack of definitive evidence regarding unprocessed red meat, research suggests that both types of meat may have negative health outcomes in the long term. It is recommended that most intake of meats and poultry should come from fresh, frozen, or canned forms rather than processed meats, due to their high levels of sodium and saturated fat.
Public health data indicates that a reduction in processed meat intake, by just 5 percent at a national level, could still yield significant health improvements, although to a lesser extent than a 30 percent reduction. Microsimulation models have estimated that cutting out 61 grams of processed meat per week could prevent thousands of cases of type 2 diabetes, cardiovascular disease, colorectal cancer, and overall mortality. These findings underscore the importance of reevaluating dietary habits and making informed choices to promote better health outcomes.
The World Health Organization (WHO) has classified processed meat as “carcinogenic,” and research has shown that consuming 50 grams of processed meat per day can increase the risk of colorectal cancer by 18 percent. The American Heart Association recommends limiting processed meat intake to around 100 grams per week, or approximately 14 grams per day. Despite these recommendations and the growing body of evidence linking processed meat consumption to chronic health conditions, the national intake of processed meat in the US has remained steady over the past two decades.
As the Dietary Guidelines for Americans are set to be updated in 2025, there is an opportunity to provide specific recommendations regarding the reduction of processed meat intake. This change could have widespread implications for food assistance programs, school lunches, and nutrition education initiatives, especially for children and young people in the US. Given the high prevalence of diabetes in the population, a simple dietary change such as reducing processed meat consumption could potentially help millions of individuals live healthier lives. It is essential for policymakers, healthcare professionals, and the general public to be aware of the impact of processed meat on public health and make informed choices to support better overall well-being.
