Although uncommon, certain individuals who are sensitive to iodine can develop acne breakouts, rashes, or other skin reactions when consuming iodine from iodized table salt or supplements such as certain multivitamins and kelp supplements. For more about this, see the Concerns and Cautions section of the Kelp Supplements Review. (Keep in mind that iodine is an essential mineral and is especially important during pregnancy, so don't avoid iodine.)
A modest association between consumption of cocoa and the development of pimples has also been shown.
