Many foods are sources of selenium, an important mineral for thyroid health and increasing thyroid hormone, such as pork, beef, turkey, chicken, cottage cheese, eggs, and brown rice. However, Brazil nuts are the richest food source of selenium, with six to eight nuts providing 550 micrograms of selenium, while all other foods contain only 30 to 50 micrograms.
The thyroid gland plays a crucial role in regulating the body's metabolism by producing and secreting hormones. A deficiency in thyroid hormones can affect various bodily functions, such as injury repair and brain tissue repair.
Many people may not be getting enough selenium in their diets, which is important for increasing thyroid hormone. While some foods like beef and eggs contain selenium, Brazil nuts are a much richer source.
