Well, I think one of the most common is iodized table salt, which really isn’t necessary to supplement people’s diets anymore in the developed world, but many people don’t know that and still use it.
Cut it out, you don’t need it. Use kosher salt for cooking and get sea salt in a grinder for seasoning, and you’ll never miss that metallic aftertaste that iodized salt leaves behind.
we need more iodine now more than ever. We should not use table salt simply for the fact that it’s been stripped of minerals and then had bleach and anti caking chemicals added to it. The miniscule amount of iodine added was at the behest of our government probably close to 100 years ago as there was a rampant rise in goiters across our nation. The goiters shrunk back down once the iodine was added but we need it for so much more.
There are now 3 very prominent toxins in our environment that mimic iodine by attaching to our iodine receptors and blocking our ability to absorb the very little we get in our diet. Those are chlorine, flouride and bromine. We need higher doses of iodine to offset the toxins but it is also crucial for reproductive health.
