A new Norweigian study has examined the connection between diet and acne.
Zits, pimples, bumps and blemishes can be a young person's worst nightmare. Collectively they are known as acne, a very common skin condition that affects millions of adolescents. Now a Norwegian study published in the open access journal BMC Public Health has investigated the links between acne, diet and mental health issues in both males and females.
University of Oslo researcher Jon Anders Halvorsen together with co-authors from Lhasa, Tibet, and Boston studied 3,775 adolescents to explore the possible causes of acne. The 18- and 19-year olds were given questionnaires to monitor their diets, lifestyle variables, and mental conditions. Participants reported on their own acne. Lastly, researchers acquired the sociodemographic status of the young people from Statistics Norway.
The study identified crude associations between acne and high intake of chocolate and chips and low intake of vegetables. In girls, there was a significant link between acne and diet low in raw and fresh vegetables. This may indicate that a low-glycemic index could have a protective role in the development of acne.
Dr. Halvorsen said, "Our study shows a possible link between diet and acne. However, when we introduced symptoms of depression and anxiety in our statistical model, the role of diet became less clear. On the other hand the association between acne and mental health problems was still strong when diet was introduced. This underscores mental health problems as an important aspect of young people's acne".
