Acne, milk and the iodine connection
Dermatologists seem to agree that something in milk and dairy products
may be linked to teen-age acne.
But is it hormones and "bioactive molecules," as a study in the Journal
of the American Academy of Dermatology suggested, or is there something
University at Buffalo dermatologist Harvey Arbesman, M.D., says there
could be something else: Iodine.
Arbesman, a UB clinical assistant professor of dermatology and social
and preventive medicine, details his reasoning in a letter published in
the "Notes and Comments" section of the current (December) issue of the
"It has been well-established since the 1960s that iodine intake can
exacerbate acne," said Arbesman. "Nevertheless, various studies have
shown there is still a significant level of iodine in milk in several
countries, including the U.S., Britain, Denmark, Norway and Italy.
"Farmers give their cows iodine-fortified feed to prevent infection," he
noted, "and they use sanitizing iodine solutions on their cows' udders
and milking equipment. Consequently, there is lot of iodine in dairy
products. For that reason, I've advised my acne patients for years to
decrease their dairy intake."
Arbesman suggests the connection between acne and dairy products
observed in the study could be secondary to the iodine content of the
dairy products. "More importantly," he said, "the connection could be a
combination of hormones and iodine."
It's important to bring the iodine connection to the fore to encourage
the dairy industry to address the issue, Arbesman said. He suggested
that future studies on the relationship of milk products and acne should
consider the role iodine content may play.
