Does Diet really affect ACNE?

The commonest question a patient will ask toward the end of acne treatment consultation. 

Population-based and migration studies have suggested a correlation between diet and acne.

Studies have demonstrated that:

1.    Diet high in dairy products is associated with an increase risk for and severity of acne.
Researchers have found significant associations between all varieties of cow's milk and acne. The relationship between milk and acne severity may be explained by the presence of normal reproductive steroid hormones or through enhanced production of polypeptide hormones such as IGF-1, which can increase androgen exposure, and hence,increased acne risk.
2.    There is an association 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.

3.  No study has established a positive association between acne and chocolate, saturated fat, or salt intake.

As a conclusion from the studies, dietary advice will be one of the main treatment modality for acne treatment. Patient should be more vigilant in selecting food that they are taking to assist in preventing from acne getting worse, and fasten the recovery of the acne.
