Diet and Acne

Acne is a common skin condition that affects millions of people worldwide, causing not only physical discomfort but also impacting self-esteem and confidence. While the exact causes of acne are multifaceted and can include factors such as genetics, hormonal changes, and skin care practices, emerging scientific evidence suggests that diet may also play a significant role in the development and severity of acne breakouts. In this article, we will explore the connection between diet and acne, focusing on scientifically proven findings and foods to avoid for clearer skin.

The Low-Glycemic Diet Approach

One dietary strategy that has gained traction in the realm of acne management is the low-glycemic diet. This approach focuses on consuming foods that have a minimal impact on blood sugar levels, thereby reducing the potential for inflammation and hormonal imbalances – both of which are known contributors to acne development.


High-glycemic foods, such as sugary snacks, white bread, and refined carbohydrates, cause rapid spikes in blood sugar levels. This triggers an inflammatory response in the body and encourages the overproduction of sebum, the oily substance that can clog pores and lead to acne. By opting for low-glycemic foods like fresh vegetables, fruits, beans, and whole grains, individuals can help stabilize their blood sugar levels and potentially mitigate the risk of acne breakouts.

Scientific studies highlighted by the American Academy of Dermatology (AAD) have supported the effectiveness of a low-glycemic diet in reducing acne:

  • In a study conducted in the USA involving 2,258 patients, those who followed a low-glycemic diet not only experienced weight loss but also reported a significant reduction in acne. Approximately 87% of patients reported fewer acne breakouts, and 91% required less acne medication.

  • Australian research involving 43 males with acne found that those who adhered to a low-glycemic diet for 12 weeks exhibited notably fewer acne symptoms compared to those who maintained their regular diet.

  • A Korean study involving 32 acne patients who switched to a low-glycemic diet for 10 weeks experienced a significant reduction in acne compared to those who continued their normal diet.

The consensus among these studies is that adopting a low-glycemic diet can potentially lead to fewer acne breakouts due to its positive impact on blood sugar levels and inflammation.

Cow's Milk and Acne

Another area of dietary consideration in acne management revolves around cow's milk. Research from AAD suggests that cow's milk, particularly skim milk, may be linked to an increased risk of acne. While the exact mechanisms behind this association are not fully understood, several studies have reported a correlation between high cow's milk consumption and acne development:

  • A study involving adult women in the USA found that those who consumed two or more glasses of skim milk per day were 44% more likely to have acne.

  • In a study involving girls aged 9 to 15, increased cow's milk consumption (whole, low-fat, or skim) was associated with a higher likelihood of acne.

  • Similarly, boys aged 9 to 15 who consumed skim milk showed an increased risk of developing acne.


The connection between cow's milk and acne is still being explored, but it is hypothesized that hormones and bioactive compounds present in milk may contribute to the development of acne. Further research is needed to fully understand the mechanisms at play.

While the exact relationship between diet and acne is complex and varies from person to person, scientific evidence suggests that certain dietary choices can influence the likelihood and severity of acne breakouts. A low-glycemic diet, characterized by the consumption of whole, unprocessed foods, has demonstrated promising results in reducing acne symptoms by stabilizing blood sugar levels and reducing inflammation. Additionally, there appears to be a potential link between high cow's milk consumption, particularly skim milk, and an increased risk of acne.

While no diet can cure acne, making specific dietary adjustments can potentially help manage symptoms and improve overall skin health. It is essential to remember that acne is a common skin condition with various triggers, and what works for one person may not work for another. Consulting with a healthcare professional or a registered dietitian can provide personalized guidance and help develop a suitable dietary approach for managing acne symptoms effectively.
