1. Why Is Iodine Important in Food?
Iodine is essential because it is a key component in the production of thyroid hormones. These hormones, thyroxine (T4) and triiodothyronine (T3), regulate metabolism, growth, and development. According to a study from the National Institutes of Health in June 2024, without sufficient iodine, the thyroid cannot produce enough of these hormones, leading to hypothyroidism.
1.1. What Role Do Thyroid Hormones Play?
Thyroid hormones are essential for:
- Metabolism: Regulating how your body uses energy from food.
- Growth and Development: Supporting proper growth, especially in children and during pregnancy.
- Brain Function: Ensuring optimal cognitive function and mental health.
1.2. What Happens If You Don’t Get Enough Iodine?
Iodine deficiency can lead to several health issues, including:
- Hypothyroidism: An underactive thyroid gland, causing fatigue, weight gain, and depression.
- Goiter: Enlargement of the thyroid gland, resulting in a visible swelling in the neck.
- Developmental Problems: In pregnant women, iodine deficiency can cause miscarriage, stillbirth, and impaired brain development in the baby.
1.3. How Much Iodine Do You Need?
The recommended daily intake of iodine varies by age and life stage. Here’s a quick guide:
- Adults: 150 micrograms (mcg) per day
- Pregnant Women: 220 mcg per day
- Breastfeeding Women: 290 mcg per day
- Children (9-13 years): 120 mcg per day
- Children (1-8 years): 90 mcg per day
According to the American Thyroid Association in July 2025, most people can get enough iodine through diet, but supplementation may be necessary in certain cases, such as during pregnancy or for those with specific health conditions.
2. What are the Best Food Sources of Iodine?
The best foods with iodine include seaweed, dairy products, seafood, and iodized salt. These foods naturally contain or are fortified with iodine, ensuring you get enough of this crucial nutrient. The U.S. Food and Drug Administration (FDA) supports fortifying food with iodine for a healthy and balanced diet.
2.1. Seaweed
Seaweed is one of the richest natural sources of iodine. Different types of seaweed contain varying amounts of iodine:
- Kelp: Highest in iodine, with some varieties containing several thousand micrograms per serving.
- Nori: Commonly used in sushi, contains a moderate amount of iodine.
- Wakame: Another good source, often used in soups and salads.
