Acne and Diet
Dr. Krakowsky shares research on how diet affects acne in his Toronto acne clinic
The good news is that while patients who are affected by the skin condition Acne vulgaris have reported a connection with diet, this connection has now been well researched. In a 2009 review of 21 observational studies and 6 clinical trials, including 2 large controlled prospective trials, data showed that cow's milk intake increased acne prevalence and severity.
Furthermore, prospective studies, including randomized controlled trials, demonstrated a positive association between a high-glycemic-load diet and acne risk. High-glycemic means that the foods are either sugary, or they're starches that are quickly converted to sugar by the body. This includes the so-called "white" foods - white flour and products made with it such as bread and pasta, potatoes, rice, white sugar and other sugars.
HIGHLIGHTS: Researchers have found significant associations between all varieties of cow's milk and acne. The relationship between milk and acne may be explained by the presence in dairy of naturally occurring hormones, or the hormones added during raising, some of which (such as IGF-1) can increase androgen exposure, and thus, acne risk. Recent findings also make a connection between a high-glycemic-index diet and longer acne duration. In addition, randomized clinical trials have demonstrated that a low-glycemic-load diet can influence hormonal levels and improve insulin sensitivity - and acne.
