Try These 7 Top Food Sources Of Iodine

Iodine sounds like a crazy chemical, but it’s actually an essential mineral. You need iodine to survive! The body uses iodine to make thyroid hormones or TH.

These molecules control everything from the muscle and heart to the kidney and brain. Even metabolism depends on thyroid hormones. The body can’t make iodine, so you need to get it through food. Eating iodine-rich sources is the best way to prevent deficiency.

About Iodine Deficiency

At least 1, 572 million people worldwide are at risk for iodine deficiency disorders, or IDD. The problem mostly affects developing countries in Africa, Latin America, Asia, and some parts of Europe.

IDD usually stems from the poor quality soil. The food grown in this soil doesn’t absorb enough iodine, so the people who eat it don’t get enough. Generally, IDD is a geographical problem, but some factors can make it worse such as.1

  • Protein-energy malnutrition
  • Contaminated drinking water
  • Diets that mess with intestinal absorption
