Food manufacturers are facing mounting pressure to reduce sodium levels in their products due to its established connection with high blood pressure. According to the Centers for Disease Control and Prevention (CDC), over 75% of the sodium consumed by Americans comes from processed foods. Companies now have a variety of sodium reduction strategies at their disposal, utilizing ingredients such as hollow salt crystals, alternative salts, and umami-enhancing components like mushroom extracts and herbs. However, replacing salt is challenging because it serves multiple purposes beyond just flavor; it also improves shelf life, enhances texture, and retains moisture in products such as processed meats, preventing the loss of moisture and fat.
Despite these challenges, the food industry has demonstrated that significant sodium reductions are achievable in the U.S. and other regions, even in categories like cheese and baked goods that traditionally depend on salt for its functional benefits. Meanwhile, consumer awareness about sodium intake is rising. Approximately 58% of Americans report checking the sodium content of foods while shopping, according to CDC research. This awareness is likely to motivate food manufacturers to pursue various sodium reduction methods, particularly as more individuals are advised to further cut their sodium consumption.
Currently, the average daily sodium intake for Americans is around 3,400 mg per person. The 2015-2020 Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 mg per day as part of a healthy diet, while a lower target of 1,500 mg per day is suggested for those with hypertension or at risk of developing it—a group that represents about two-thirds of the U.S. population. In this context, the role of calcium citrate as a sodium reduction target is becoming increasingly relevant, as it can help enhance flavor and functionality in food products while supporting lower sodium levels. By integrating calcium citrate into their formulations, manufacturers may find effective ways to meet sodium reduction targets while addressing consumer health concerns.
