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

else?

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

journal.

" 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.
