low iodine diet

Low iodine diet is a therapeutic diet that limits the intake of iodine-rich foods.

Iodine is an essential mineral that is required for the production of thyroid hormones, but excessive iodine intake can interfere with thyroid function and cause health issues.

A low iodine diet is often recommended for people with thyroid conditions or for those who are preparing for a radioactive iodine scan or treatment.

If you’re following a low iodine diet, it’s important to know which foods to avoid and which foods to include in your diet.

In this article, we’ll provide you with a low-iodine diet shopping list that can help you plan your meals and snacks.

Foods to avoid on a low-iodine diet:

  1. Iodized salt: Table salt that is iodized should be avoided on a low-iodine diet. Instead, use non-iodized salt or sea salt.
  2. Seafood: All types of seafood, including fish, shellfish, and seaweed, are rich in iodine and should be avoided on a low iodine diet.
  3. Dairy products: Milk, cheese, yogurt, and other dairy products are usually iodine-rich and should be avoided. Instead, try plant-based milk alternatives like almond or oat milk.
  4. Processed foods: Processed foods like canned soups, packaged snacks, and frozen meals often contain iodized salt or other iodine-rich ingredients.
  5. Other iodine-rich foods: Some fruits, vegetables, and grains like strawberries, potatoes, and wheat can contain iodine and should be avoided or limited on a low iodine diet.

Foods to eat on a low iodine diet:

  1. Fresh fruits and vegetables: Most fresh fruits and vegetables are low in iodine and should be included in your diet. Some examples include apples, bananas, oranges, broccoli, carrots, and kale.
  2. Whole grains: Whole grains like brown rice, quinoa, and oats are generally low in iodine and can be included in your diet.
  3. Unsalted nuts and seeds: Nuts and seeds like almonds, cashews, and pumpkin seeds are a good source of protein and healthy fats on a low iodine diet.
  4. Fresh herbs and spices: Fresh herbs and spices like garlic, ginger, and turmeric can add flavor to your meals without adding iodine.
  5. Other low iodine foods: Other foods that are typically low in iodine include unsweetened nut butter, plant-based oils, and dried beans and lentils.
