Iodine-Fortified Potatoes: Addressing Thyroid and Cognitive Health.


Iodine is an essential trace element required for thyroid hormone production, brain function, and metabolic regulation. Iodine deficiency disorders (IDD) affect nearly 30% of the global population, leading to conditions such as goiter, hypothyroidism, and cognitive impairments in children.

  • In many developing nations, iodine deficiency is still a major public health issue, as access to iodized salt and seafood—natural sources of iodine—is limited.
  • Iodine-enriched potatoes are being introduced as a dietary intervention in regions with high rates of IDD, ensuring that people receive sufficient iodine through their regular food intake.
  • Research shows that biofortified potatoes with iodine can help reduce the risk of cognitive developmental delays in children and improve thyroid function in adults.

By integrating iodine into a widely consumed staple food, potato biofortification programs offer a practical and sustainable way to combat iodine deficiency disorders on a global scale

It’s a good idea to inspect your potatoes before you buy them . A little dirt is fine and perfectly normal, but you want to watch out for and avoid any sprouting from the eyes (the little indents in the potato), soft spots, cuts and gouges, or any potato with a green tint to the skin.

Such a potato also will have a bitter flavor.

Eaten by over one billion people , the potato is the third most available food crop globally – after rice and wheat, making it a crucial staple. And today for the first time, it was celebrated with its very own International Day, as the Food and Agriculture Organization of the United Nations (FAO) and partners highlighted the potato’s significance and called for more investments to tap into its full potential. “The potato has been the most important lifesaving, staple food and nutritious vegetable in the world,” FAO Director-General QU Dongyu said in a video message to mark the event, under the theme of “Harvesting diversity, feeding hope”. Qu added that in Europe, the increase of potato production after the 16th century following Christopher Colombus’ return from the Americas with the potato, which originated in the Andes, has impacted food security dramatically. Participants in a high-level event at FAO’s headquarters to mark the day included Angel Manuel Manero Campos, Minister of A...
