Dermatologists found a link between acne and high levels of iodine, which is found in foods such as shellfish. High levels of iodine are also found in dairy products, because the cows are fed iodine-enriched feed to prevent infection.
When iodine enters the body and mixes into your bloodstream, the excess is secreted through the oil glands, irritating your pores. So drinking milk could be aggravating your skin.
But you don't have to give up your love of milk, butter, or cheese. Just switch to an Organic version that contains less iodine.
Fit's Tip: If you love sushi, be aware that the nori wrap contains huge amounts of iodine - 1,020 parts per million as compared to 26 in butter.
