The first nutrient is iodine. Iodine deficiency affects more than 2.2 billion people worldwide. There are a couple of reasons why it has gotten so bad. Until recently, about 25% of the iodine in the diet was from wheat, because iodine was used in the processing of flour. Now most of it is processed with bromide. What makes it even worse is that bromide inhibits the activity of iodine already in your body. The same goes for the other halogens flouride and chlorine, which are both in our water supply. From 1971 to 2011 iodine intakes in the US dropped by 50%.
Iodine plays a key role in the production of thyroid hormones. Every cell in the body depends on these hormones for regulation of their metabolism. Increased thyroid hormone levels stimulate fat mobilization and almost all aspects of carbohydrate metabolism.
Like in my previous video on sodium, I recommend a good iodized sea salt. There aren’t many foods that naturally contain iodine. As far as supplements go, nascent iodine is the most bioavailable form. But there is controversy about this free form iodide actually remaining a singular atom by the time you take it. You may just be paying big bucks for a “nascent iodine” that’s actually potassium or sodium iodide. I use the potassium iodide product pictured here.
Next up is vitamin D. About half of all Americans are deficient in vitamin D. This is a lot like iodine in the fact that we don’t usually get much from the diet. Sunshine is the best source and that’s just not reliable to many people geographically.
Vitamin D helps the body absorb weight loss nutrients while also optimizing the efficiency of our metabolism. On top of that, when vitamin D is low, hormones signal for more fat storage.
Now you can get a little bit of vitamin D from fatty fish and fortified foods. The only vitamin D I really eat comes f..
