5. Milk
When most people think of milk, they think of vitamin D and calcium. While yes, it is true that milk is an excellent source of both of these vital nutrients, it also contains other important nutrients, including iodine. A single cup of milk contains about 56 mcg of iodine or around 37 percent of the daily recommended intake. So, go ahead and drink a glass or two of milk (add some low-calorie chocolate for some flavor,) or add it to your smoothies. To get the most health benefits, choose a low-fat organic variety.
