Nutrients are essential to lead a healthy life as they have a direct impact on your physical and mental health. Did you know that iodine deficiency is one of the key micronutrient deficiencies affecting people and their health? Iodine is crucial to help our bodies to function properly. It is an important dietary mineral for your thyroid gland as well. An iodine deficiency can have a huge impact on the thyroid gland and lead to problems.
Here’s everything you need to understand the link between iodine and thyroid.
The link between iodine deficiency and thyroid
Iodine is an essential mineral that your thyroid gland uses to make thyroid hormones. Sufficient levels of iodine help control thyroid growth, repair damaged cells and keep your metabolism in check. Unfortunately, iodine deficiency poses a threat of up to a third of the world’s population. While there are several symptoms of iodine deficiency, the most prominent of them all is an enlarged thyroid or hypothyroidism, as per the study published in the Lancet Diabetes & Endocrinology.
The thyroid gland stores iodine, an important dietary mineral. All of the cells in the human body are impacted by thyroid hormones, which are crucial for healthy cell formation. So, it is necessary for the thyroid hormones triiodothyronine (T3) and thyroxine (T3) to be produced (T4) in your body. The metabolism of protein, fat, and carbohydrates in cells is tightly correlated with thyroid hormones, as per Harvard T.H. Chan School of Public Health.
