Micronutrient 101: Minerals - Iodine
by Jowynna Yeo - 30th Sep 2019
Iodine... No, it's not just a solution for lab experiments.
Iodine is one of the essential trace minerals as our human body cannot produce Iodine, hence it must come from our diet.
Iodine plays an important role in the synthesis of thyroid hormones - which are essential for life.
But no, we don't get Iodine from the iodine solution/Lugol's iodine. (Do not drink it!)
The Iodine content of foods depends on the iodine content of the soil in which the food is grown. Besides this, seawater is also a rich source of iodine - which makes seaweeds and fish (which feeds on seaweed) are rich sources of iodine.

Fun fact: Populations living near the sea and consuming seaweeds and reef fish, such as Japanese, have high intake of iodine in their diet. Wow!
Other food sources of iodine include eggs, meat, milk and milk products, cereal grains, dried legumes, dried vegetables and dried fruits.
Eat more seaweed!
