9. Table salt
Despite what your misguided health practitioner might have told you, salt is essential for healthy living. In fact, without salt, your cells would quickly wither and die. The problem with salt lies with the table variety — these salts are processed to the point where your body is unable to recognize them, meaning they make you dehydrated and introduce your digestive system to dangerous chemicals like ferrocyanide and aluminosilicate. Get your salt from unprocessed sources like Himalayan pink salt and unrefined (gray) sea salt, and stay well away from sodium-rich processed foods.
