Our thyroid plays a huge role in functioning of the body. It produces hormones that regulate metabolism, mood, energy levels, heart rate, body temperature and blood pressure. Many health problems start emerging when our thyroid stops working optimally. Along with taking thyroid medication, you can boost your thyroid function by eating right food.
Thyroid needs specific nutrients to function optimally. The first and foremost essential nutrient that is needed for optimal thyroid function is iodine. Other important nutrients you need for proper thyroid function are selenium, zinc, and iron.
Following 10 foods are best dietary sources of these essential nutrients. These foods are also high in nutrients like high quality probiotics, proteins, antioxidants and necessary vitamin needed for hormone production.
