The Connection Between Diet and Acne: What Does the Research Say?

For years, the link between diet and acne has been a topic of debate among dermatologists, nutritionists, and skincare enthusiasts. Many teens and parents wonder if certain foods might be making acne worse or whether changes in diet could help clear up the skin. Although research is ongoing, several studies have provided evidence suggesting that dietary choices can indeed play a role in the development and severity of acne. Understanding this connection can empower you to make more informed decisions about what you eat and how it might impact your skin health.

While it’s important to note that there is no single cause of acne—factors such as hormones, genetics and skincare habits all contribute—dietary choices can influence the skin’s condition. Here’s an overview of the most recent research findings on diet and acne:

One of the most well-researched areas regarding diet and acne is the effect of high glycemic index (GI) foods. High GI foods, such as sugary snacks, white bread, and refined carbohydrates, cause a rapid spike in blood sugar levels. This spike leads to increased insulin production, which in turn can raise levels of androgens (hormones that stimulate the production of sebum, or oil, in the skin).

Studies have shown that a high glycemic diet is associated with an increase in acne severity. A study published in the Journal of the American Academy of Dermatology found that participants who followed a low-glycemic diet experienced a significant reduction in acne lesions compared to those who consumed a high-glycemic diet. The researchers concluded that lowering blood sugar levels through diet might help reduce excess sebum production, thereby reducing acne outbreaks.

Another dietary factor that has been linked to acne is the consumption of dairy products. Several studies suggest that milk, particularly skim milk, may contribute to acne development. The exact reason is still under investigation, but some theories suggest that hormones present in milk or the insulin-like growth factor (IGF-1) could play a role.

A large study involving over 47,000 women found that those who consumed higher amounts of milk had a greater likelihood of experiencing acne. Another study conducted among adolescents also reported a positive association between milk intake and the prevalence of acne. While the research does not suggest eliminating dairy entirely, moderating intake or choosing alternatives like almond or oat milk might help reduce breakouts in some individuals.

Omega-3 fatty acids, commonly found in fatty fish, walnuts and flaxseeds, are known for their anti-inflammatory properties. Research suggests that a diet rich in omega-3s may help reduce inflammation in the body, which is a key factor in the development of acne.

A study published in Lipids in Health and Disease found that participants who took omega-3 supplements experienced a significant reduction in both inflammatory and non-inflammatory acne lesions. This suggests that incorporating more omega-3 rich foods into the diet could be beneficial for those struggling with acne.

Based on current research, here are some dietary tips that may help improve acne:

Opt for Low-Glycemic Foods: Choose whole grains, fruits, vegetables and legumes over refined carbs and sugary snacks.

Moderate Dairy Intake: Consider reducing your consumption of milk and other dairy products or switching to non-dairy alternatives.

Include Omega-3 Rich Foods: Add sources of omega-3 fatty acids like salmon, chia seeds and walnuts to your meals to reduce inflammation.

While diet alone may not be the sole factor in acne development, it can certainly influence the condition of your skin. By paying attention to the foods you eat and making mindful dietary choices, you may see improvements in your acne symptoms. Remember, everyone’s skin is different, so it’s essential to observe how your body reacts to specific foods and consult a nutritionist for personalized advice.
