The Hidden Burden of Water‐Binding Additives in Meat Products: Biochemical, Clinical, and Psychosocial Implications

ABSTRACT

Processed meat products are widely consumed worldwide, especially because they are affordable and easy to prepare. Their production often involves the use of water‐binding additives such as phosphates, nitrites, and sodium chloride. Although these substances improve taste, texture, and shelf life, their potential effects on human health remain unclear. This review aims to summarize current knowledge about the possible biological and clinical effects of these additives. Injection (brining) technology is commonly used to increase product weight and improve quality. However, it may also lead to regular consumption of these additives. Phosphates may influence mineral balance and could be linked to changes in vitamin D metabolism and vascular health. Nitrites can participate in the formation of N‐nitroso compounds, which have been shown to have harmful effects in experimental studies. High sodium intake is associated with increased blood pressure and cardiovascular risk. Some studies also suggest that these additives may affect the gut microbiota and promote low‐grade inflammation. Certain groups, including people with chronic diseases, may be more sensitive to these effects. Cultivated meat has been proposed as a potential alternative that may reduce reliance on such additives; however, it often still requires similar ingredients to achieve desired texture and stability, and its potential health benefits remain uncertain. Current regulations in the United States and the European Union primarily focus on individual additives and do not fully account for total daily intake from different foods. In addition, food labels often do not provide detailed quantitative information. Further research is needed to better understand long‐term effects and combined exposure.
