Health Benefits of Iodine
Healthy Brain Development
You would be surprised to know that iodine deficiency is identified as the number 1 cause of mental retardation across the globe.
Iodine has had such a huge impact because it is an extremely important mineral for healthy brain development. The strongest damage of this deficiency is caused by a baby’s brain which can even result in life-long brain damage.
Iodine is an essential nutrient to have in the system all along but it becomes even more important during pregnancy where thyroid hormones are controlling the growth of the brain. If the deficiency isn’t too severe, it results in kids having below-average IQ.
Once kids start growing, a deficiency in iodine impacts their intellectual and motor performance along with increasing the risk of ADHD.
Liquid iodine can be applied externally to help treat infections. It kills the bacteria inside the affected area and prevents them from further spreading. You can use it around cuts, scrapes and wounds to prevent further infection.
A word of caution would be to not use topical iodine on infants and on deep cuts as it may have negative effects.
Controls Metabolic Rate
Our body’s base metabolic rate is controlled by the hormones produced by the thyroid glands and iodine plays a key role in this process by helping the thyroid glands produce these hormones. The metabolic rate is essential in the efficient working of our organs. Metabolic rate is also responsible for day-to-day processes like sleeping, absorption of food and converting food into energy.
Hormones from thyroid glands like control heart rate, body weight, and blood pressure. Also, the body maintains its basic metabolic rate through the influence of these hormones.
Further, these hormones also help with protein synthesis. The normal creation and even distribution of proteins are extremely crucial in maintaining a healthy body.
Maintains Healthy Levels of Energy
Iodine ensures that the calories get utilized in an efficient way and does not allow calories to get deposited in our problem areas in the form of fats.
That’s how Iodine plays a powerful role in maintaining sufficient energy levels in the body.
