SAN FRANCISCO (Reuters Health) Mar 09 - Most patients with acne report an improvement in their condition when they follow the low-glycemic diet originating in Florida known as the South Beach diet, researchers reported here at the 67th Annual Meeting of the American Academy of Dermatology (AAD).
Panta Rouhani, PhD, with the University of Miami, and colleagues analyzed 41-item questionnaires completed by 2,528 patients who said that they were on the diet at the time they completed the survey and 467 who were not following the diet.
"Today, it is generally accepted by dermatologists that diet and acne are not related; however, this notion is based on only two primary references," the authors wrote in their poster presentation.
"Diet is a well-recognized factor in acute and chronic hyperinsulinemia," they added. "Recent evidence suggests that diet-induced hyperinsulinemia triggers a hormonal cascade, eliciting an endocrine response that simultaneously triggers unregulated epithelial growth and keratinization as well as androgen-mediated sebum secretion."
The South beach diet mimics the nutritional characteristics of diets found in non-Westernized populations known to be acne-free, they said. It is free of processed foods, cereal grains, dairy products, refined sugars, and refined oils and almost entirely comprised of unprocessed fresh fruits, vegetables, and lean meats, fish, and seafood.
Whether adherence to a low-glycemic diet can alter acne in Western populations is unknown.
In the study, patients with acne lesions (75.3%) were asked if any changes in their skin occurred and whether these changes were improvements in their acne.
Overall, 86.7% reported noted skin changes to be improvements (90.7% of those on acne treatment versus 81.7% of those untreated, p < 0.001).
Most (86.7%) noted these improvements within 3 months of starting the South Beach diet (58.0% of those on acne treatment versus 42.0% of those untreated, p = 0.34).
Of patients on conventional acne treatment, 91.0% either reduced the dose or amount of treatment they were using.
The investigators said that the improvement in acne after a low-glycemic diet suggests that lifestyle factors such as nutrition may indeed play a role in the pathogenesis of acne.
They added that future research is needed to further clarify the underlying pathophysiologic mechanism and independent roles of nutrition, weight loss, and exercise.
