pöytäsuolasta

Pöytäsuola, scientifically known as sodium chloride (NaCl), is a crystalline mineral compound commonly used as a seasoning in food and as a preservative. It is composed of equal parts sodium and chlorine ions. In its pure form, it is white and odorless. Table salt is a vital nutrient for human life, playing a role in nerve function, muscle contraction, and maintaining fluid balance in the body.

Historically, salt has been highly valued for its ability to preserve food before refrigeration was widely available. Its antimicrobial properties inhibit the growth of bacteria, thus extending the shelf life of various food products. Different cultures have developed unique uses for salt in their cuisines, with variations in grain size, additives, and flavor profiles.

Commonly, table salt is iodized, meaning iodine has been added to prevent iodine deficiency disorders, such as goiter. Other additives may include anticaking agents to prevent clumping. The extraction of salt occurs through mining rock salt deposits or evaporating seawater or salt lakes. Despite its widespread availability and low cost, the overconsumption of sodium chloride can have negative health consequences, including increased blood pressure.
