Salt is a mineral substance composed primarily of sodium chloride, which is essential for the human body to function properly. It is commonly used as a seasoning in cooking, as well as a preservative and flavor enhancer in food processing. Research in the area of salt, also known as salt research or salt science, focuses on understanding the effects of salt on health, the environment, and various industries. This includes studying the impact of salt consumption on blood pressure, cardiovascular health, and overall well-being, as well as exploring sustainable salt production methods and addressing challenges related to salt pollution and waste management. Salt research is interdisciplinary, drawing on fields such as nutrition, medicine, chemistry, geology, and environmental science.
