Tuna is good for the thyroid gland
Tuna contains fat-soluble vitamins A, E and D, as well as many minerals such as phosphorus, iron, calcium, selenium and iodine.
Selenium, along with iodine, is essential for the synthesis of thyroid hormones and helps to improve the functioning of the human immune system.
Canned tuna is almost as healthy as fresh tuna. However, when cooking, it is important to take into account the high salt and oil content of such tinned products.
