Is Iodised Salt Healthy or Unhealthy?
Iodised salt is table salt that has been mixed with a small amount of iodine, a mineral that is essential for human health. Iodine is added to salt because it helps to prevent iodine deficiency disorders (IDDs), a group of preventable conditions that can cause a variety of health problems, including:
- Goiter, a swelling of the thyroid gland
- Hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone
- Intellectual disability
- Cretinism, a severe form of intellectual disability caused by iodine deficiency in pregnant women
Iodine is an essential nutrient for humans, and iodised salt is a safe and effective way to prevent IDDs. However, some people have concerns about the health effects of iodised salt, particularly the potential for excessive iodine intake.
Potential Health Concerns
Excessive iodine intake can lead to a number of health problems, including:
- Iodine-induced hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone
- Thyroiditis, an inflammation of the thyroid gland
- Hashimoto's thyroiditis, an autoimmune disease that affects the thyroid gland
The risk of developing these health problems from iodised salt is very low, but it is important to be aware of the potential risks. If you have any concerns about your iodine intake, you should talk to your doctor.
Overall
Iodised salt is a safe and effective way to prevent IDDs. However, it is important to be aware of the potential risks of excessive iodine intake. If you have any concerns about your iodine intake, you should talk to your doctor.
