In Canada, many salt varieties are low in iodine, essential for thyroid hormone production. Despite table salt being iodized since 1949, iodine deficiency remains a concern due to low iodine levels in Canadian soil, affecting food crops. Sources of iodine include seafood and dairy, yet some Canadians are at risk, leading to health issues like goitres. Dr. Anna Banerji has witnessed iodine deficiency cases in new immigrants, highlighting the need for awareness and dietary adjustments to prevent severe iodine deficiency conditions.
Not having enough iodine could lead to a variety of health conditions, like goitres—a large, usually benign swelling of the thyroid gland.
Iodine deficiency is predominantly due to the lack of iodine in the soil, meaning many crops grown here are also iodine-deficient.
