Your diet just might be causing your acne, thanks to a common ingredient hiding in many foods and supplements.
Although most experts agree that chocolate and greasy foods do not cause acne, research supports that sugar, peanuts, and, most important, iodides (also known as iodized salt, potassium iodides, or seaweed) can worsen acne.
Once iodides enter the body and mix in the bloodstream, the excess is excreted through the sweat glands. As they are excreted, iodides irritate the pores and causes acne flare-ups. Iodides are especially irritating to the susceptible pores of the acne-prone person, but large amounts can induce acne in anyone.
Iodides show up in unexpected foods, like bread, meat, and dairy products. Vitamins, minerals, and other supplements are some of the biggest sources of iodides. Many supplements include seaweed in the form of algae, carrageenan, kelp, chlorella, and spirulina, so be sure to read the ingredient labels carefully before purchasing them and throw out any that you already own. Iodide ingredients in pre-packaged items and vitamins are typically be listed as potassium iodide or simply “salt.”
