A healthy diet is a great way to ensure you receive a good balance of the nutrients your body requires, including iodine — and you need to make sure you always have enough iodine. Your thyroid depends on it to function and it is the primary element of two essential hormones that regulate metabolic function. Without it, a myriad of problems can occur, including hypothyroidism and reductions in energy.
What are some of the best sources of iodine? In this case, the best place to start is the sea…
1. Sea Vegetables
Oceans contain most of the world’s naturally occurring iodine. As a result, many of the edible plants we harvest from our saltwater seas also contain healthy values of iodine. Dulse Seaweed, Kelp, Kombu, Nori, Sea Palm and Wakame contain iodine.  Although these sea veggies offer varying amounts of iodine, they still top the list as one of the best sources for naturally occurring iodine.
It’s important to be aware of the presence of toxic metals in some fish… unfortunate but true. And, depending on your diet, you may not even eat fish. But, if you do, wild caught, deep water fish like Cod, as well as shellfish and shrimp also offer healthy values of iodine.
Same goes for eggs, not on everyone’s plate but it is worth mentioning that this nutrient powerhouse has been recommended for pregnant women and young children specifically for its iodine content.  One egg contains nearly 16% of the recommended daily value of iodine. Cage-free, organic, and vegetarian fed are a must. If you’ve got a yard, give a thought to even getting your own chickens.
4. Organic Dairy
Not everyone consumes dairy but some people do, for those folks, do know that one cup of milk contains more than one-third of the recommended daily value of iodine. Yogurt and cheese also contain iodine. Cheese contains a lower value of iodine per serving; however, one cup of yogurt contains more iodine than a cup of milk – 50% of the recommended daily value!  Recent studies have found that individuals who regularly consume dairy receive good iodine supplementation.  This is one choice especially where organic is a must, and preferably raw.
Constipated? Eat some prunes. But more than that, prunes offer a lot more than fiber. Like strawberries, prunes provide a healthy serving of iodine and other powerful nutrients in an easy to digest form.
7. Spinach and Dark Leafy Greens
Spinach, turnip greens and swiss chard have been specifically noted for their dietary iodine values.  These nutrient dense veggies also offer a highly bioavailable food source for easy digestion.
8. Dietary Supplements
If you’re not getting enough iodine in your diet, for crying out loud, do not simply shrug it off as a loss. Iodine deficiencies can cause problems and it’s so easy to avoid that mess. A nascent iodine supplement is easy to add to your daily routine and does not cost a lot. Be sure that you select a product that offers the most bioavailable materials. There are many fine products available, but there are also supplements that have been created in a lab and include artificial versions of nutrients – versions the human body may not recognize and absorb as well.
Eat the right foods, take a supplement if you need one, and make sure you get enough iodine to keep your thyroid healthy and your metabolism charged!
