Sodium Nitrite/Nitrate: Preserving Meats at What Cost?
When you enjoy a hot dog at a baseball game, bacon with your breakfast, or salami on your sandwich, you have likely consumed sodium nitrite or sodium nitrate. These compounds are commonly used in curing meats, contributing to their distinctive color and flavor and preventing the growth of harmful bacteria (National Center for Home Food Preservation, 2015).
However, the safety of these substances is under scrutiny. When cooked or broken down in the stomach, nitrites can form nitrosamines, compounds found to cause cancer in animals (National Cancer Institute, 2015). Human studies have also found associations between diets high in processed meats and an increased risk of certain types of cancer, including colorectal cancer (Bouvard et al., 2015).
Despite these concerns, both the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) currently allow the use of sodium nitrite and sodium nitrate in food production, albeit at regulated levels (FDA, 2018; EFSA, 2017). This is mainly because the risk of bacterial contamination, particularly with botulism, outweighs the potential risk of cancer (National Center for Home Food Preservation, 2015).
The debate continues. Many health-conscious consumers and food producers seek alternatives to traditional curing agents, such as celery juice, which naturally contains nitrates. However, these alternatives may have their risks (Sindelar & Milkowski, 2012).
This complex issue highlights the need for ongoing research, balanced risk assessment, and informed consumer choices. What are your thoughts on using sodium nitrite and sodium nitrate in food? Do you consider these factors when choosing what to eat?
