Low iodine diets are often prescribed as part of thyroid treatments, or prior to testing for thyroid conditions.

If you need to follow a low-iodine diet, you can still consume a range of healthful foods and follow a balanced diet.
Most beverages are acceptable on a low iodine diet. Coffee, tea, cola, diet cola, water, lemonade, beer, wine and fruit juices are all allowed. Any soft drink or juice with red dye, as well as all dairy products are forbidden on a low iodine diet.
