Many people enjoy bread daily, but are unaware of its potential effects beyond satisfying hunger. Research suggests a link between bread consumption, particularly among teenagers, and acne prevalence.
US dermatologists have found that refined sugar, wheat, and other grains can elevate insulin levels. Previous studies indicate that elevated insulin may contribute to acne. This could explain why some individuals experience fewer acne breakouts on low-carbohydrate diets.
Loren Cordain of Colorado State University suggests that refined bread, due to its easy digestibility, may trigger insulin surges and the production of IGF-1, an insulin-like growth factor. This combination can increase male hormones, leading to increased sebum production in the skin. Sebum, a thick, oily substance, can clog pores and foster the growth of bacteria responsible for acne.
Studies have also noted a lower incidence of acne in populations with diets primarily consisting of unprocessed foods. For instance, acne became prevalent among the Inuit people of Alaska only after they transitioned from their traditional diet to a Western-style diet.
Dermatologists at RMIT University in Melbourne, Australia, are conducting a study to investigate the impact of a low-carbohydrate diet on acne. The study will monitor 60 teenage boys over three months.
Dermatologists have observed encouraging results when patients adopt low-carbohydrate diets. The Australian study is a controlled experiment designed to examine the potential benefits of a low-carbohydrate diet on acne.
