Over 2 billion people worldwide are estimated to suffer from insufficient iodine intake, making iodine deficiency a major public health concern. The answer to why they add iodine to table salt lies in a simple yet highly effective campaign to combat widespread iodine deficiency disorders (IDD) and their serious health consequences, including enlarged thyroid glands and developmental issues.

Worldwide, iodine deficiency is the most common cause of goiter, an abnormal enlargement of the thyroid gland. While often mistaken for a vitamin, the essential trace mineral iodine is the primary nutrient required to prevent goiter in most cases. A balanced diet rich in iodine is the most effective preventative measure against this condition.

According to the World Health Organization, iodine deficiency is the single most common cause of preventable intellectual disability globally. This statistic underscores the critical importance of a specific salt mineral the body needs to make thyroid hormones. This essential mineral, iodine, is vital for proper metabolic function and brain development, especially during infancy and pregnancy.

Worldwide, the most common cause of goiter is iodine deficiency, a mineral, not a specific vitamin deficiency. This common misconception can lead people to overlook the true nutritional cause of this thyroid enlargement. In this article, we'll explain **what vitamin deficiency is goiter** (and why that's a misnomer) by exploring the critical role iodine plays in thyroid health.

An estimated 2.2 billion people worldwide live in areas with an iodine deficiency, the single most common cause of goiter. While many assume a specific vitamin causes goiter disease, the culprit is actually a mineral: iodine. The thyroid gland requires iodine to produce hormones, and when levels are insufficient, the gland enlarges in an attempt to compensate, leading to a visible swelling in the neck known as a goiter.

Worldwide, iodine deficiency is the most common cause of a goiter, which is a swelling of the thyroid gland. This essential trace mineral is critical for producing thyroid hormones, and a lack of it forces the thyroid to enlarge in a compensatory effort. While modern public health initiatives have reduced its prevalence, iodine deficiency remains a significant global health concern.
