Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white metal that is highly reactive and is classified as an alkali metal. Sodium is an essential nutrient for human health and plays a vital role in various physiological processes, including fluid balance, nerve function, and muscle contraction.
Sodium is found in various forms, including sodium chloride (commonly known as table salt), which is the most common dietary source of sodium. It is also present in many processed foods, such as canned foods, snack foods, and condiments.
The human body requires a small amount of sodium to maintain proper fluid balance and blood pressure. However, excessive sodium intake can lead to health problems, including high blood pressure, heart disease, and stroke. Therefore, it is important to consume sodium in moderation and to choose low-sodium food options when possible. The recommended daily intake of sodium for adults is no more than 2,300 milligrams per day, but this amount may vary depending on factors such as age, sex, and health status.
