Abstract :

Excessive sodium consumption is a major contributor to hypertension, cardiovascular disease, and other chronic health risks worldwide. While sodium plays critical roles in food--enhancing f lavor, preserving quality, and influencing texture--modern intake levels far exceed physiological needs. Reducing sodium intake through reformulated foods is a key public health goal, yet presents technological and sensory challenges. This paper examines the physiology of salt taste perception, the health impacts of excess sodium, and current strategies to reduce sodium in processed foods. It reviews three primary approaches: the stealth reduction of sodium content, the use of salt alternatives such as potassium chloride (KCl), monosodium glutamate (MSG), and plant-derived seasonings, and advanced f lavor enhancement technologies including salt microspheres, emulsions, and nanotechnology. Real world examples demonstrate that significant sodium reduction can be achieved while maintaining consumer acceptance. Together, these innovations offer promising pathways to lower population sodium intake and improve cardiovascular health outcomes.
