Iodized Salt vs. Non-iodized Salt: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 7, 2023
Iodized salt contains iodine, an essential nutrient preventing thyroid issues, while non-iodized salt lacks it, offering pure saltiness without the added nutrient.
Key Differences
Iodized salt notably contains iodine, a crucial nutrient that supports thyroid function and regulates metabolism. Non-iodized salt, on the other hand, is simply salt that does not have iodine added to it. Both serve the basic culinary purpose of enhancing the flavor of food, yet the presence or absence of iodine is what distinctly sets them apart.
In the context of health implications, iodized salt has been a significant player in preventing iodine deficiency disorders. Contrarily, non-iodized salt, while it provides the basic flavor-enhancing properties of salt, does not contribute to iodine intake, making it less impactful in addressing iodine deficiency. The iodine in iodized salt is often derived from potassium iodate, ensuring that it contributes to daily iodine nutritional requirements.
From a culinary standpoint, iodized salt and non-iodized salt can often be used interchangeably in recipes. However, certain culinary applications prefer the use of non-iodized salt due to its pure, unaltered flavor, free from the slight, additional taste that iodine can impart. This implies that, depending on the culinary application, one might be chosen over the other for flavor reasons.
While both iodized and non-iodized salt can derive from various sources, such as sea or rock salt, the primary differentiation remains in the addition of iodine. Many countries endorse the use of iodized salt as a public health measure, ensuring that populations receive adequate iodine. On the flip side, non-iodized salt is often chosen for certain culinary or manufacturing applications to ensure that no additional flavors impact the final product.
In terms of availability, iodized salt is commonly found in grocery stores and has been a staple in various households to prevent iodine deficiency. Non-iodized salt is also readily available and might be chosen for specific dietary or culinary purposes, particularly where the flavor of iodine might be undesirable or where individuals seek a purer salt flavor.
