Iodine is one of the trace elements our bodies need, along with minerals like selenium and manganese, and is best known for its role in thyroid function. Low levels of iodine in adults can affect thyroid function as iodine contributes to the normal production of the thyroid hormones as well as normal thyroid function. Thyroxine and triiodthyronine are the two main hormones produced by our thyroid gland. Our thyroid is the part of our body that helps to control metabolism. An under active thyroid can lead to low energy levels and weight gain as well as dry skin, hair loss and sluggish digestion. The thyroid is also involved in protein synthesis.
Iodine contributes to normal cognitive function and the maintenance of normal skin and a normal nervous system. It also plays a role in overall energy metabolism.
The amount of iodine that we get from our food depends on how much iodine is naturally found in the soil. If there is a lot of iodine in the soil, then plants and animals can pick up iodine. We can then get this iodine through eating these foods. In Ireland, however, our soil is relatively low in iodine so we can't rely on vegetables and meat to get all we need. Dairy foods like milk contain iodine and fish is one of the other good foods to choose.
Fish is a great source of iodine as iodine is abundant in the sea. And not just fresh fish - tinned fish like John West Wild Pink or Red Salmon is a great source. 100g of tinned salmon will give you ½ of the iodine you need for the day. The recommended daily amount for iodine is 150 micrograms. Try it in salads and sandwiches mixed with some sweetcorn and a little mayonnaise or check out our John West Infusions Salmon Teryiaki recipe featured on Ireland AM this week – a delicious stir fry ready in minutes.
