Linked to Acne
A high-refined carbohydrate diet, which includes sugary foods and drinks, has been linked to an increased risk of acne. Processed sweets and other foods with a high glycemic index raise blood sugar faster than foods with a lower glycemic index.
Sugary foods spike blood sugar and insulin levels quickly, resulting in increased androgen secretion, oil production, and inflammation, all of which contribute to acne development. Low-glycemic diets have been related to a lower risk of acne, while high-glycemic diets have been linked to greater risk. For example, a study of 2,300 adolescents found that those who consumed added sugar often had a 30% higher risk of developing acne. In addition, compared to more urban, high-income areas, many population studies have revealed that rural communities that consume traditional, non-processed foods had almost non-existent rates of acne. These data support the theory that a diet high in processed, sugary foods contributes to acne development.
