Does diet affect hormonal acne?

Diet's Impact on Hormonal Acne

Emerging evidence strongly suggests that dietary modifications, particularly adopting a low glycemic load diet and reducing dairy consumption, can significantly improve hormonal acne. 1

Key Dietary Factors Affecting Hormonal Acne

Low Glycemic Load Diet

• Multiple randomized controlled trials demonstrate that low glycemic load diets improve acne severity 2, 1
• A 2024 study showed significant improvement in acne severity among females following a low glycemic load diet, with average severity decreasing from 2.68 to 1.56 over 12 weeks 3
• Mechanism: High glycemic foods increase insulin and insulin-like growth factor 1 (IGF-1) levels, which stimulate sebum production and androgen hormone release 3, 4

Dairy Consumption

• Observational studies show a positive association between dairy consumption and acne, with skim milk showing the strongest association 2, 1
• Women consuming ≥2 glasses of skim milk daily had a 44% increased risk of reporting acne 2
• A 2020 JAMA Dermatology study found significant associations between current acne and consumption of milk (adjusted odds ratio [aOR], 1.12) 5

Other Dietary Factors

• Sugary beverages (aOR, 1.18) and fatty/sugary products (aOR, 1.54) were associated with current acne in adults 5
• Energy-dense dietary patterns with high consumption of fatty and sugary products showed significant association with current acne (aOR, 1.13) 5
• Limited evidence exists for potential benefits of omega-3 fatty acids, antioxidants including zinc, and probiotics 1

Practical Dietary Recommendations for Hormonal Acne

1. Adopt a Low Glycemic Load Diet:

   • Choose whole grains instead of refined carbohydrates
   • Limit added sugars and sugary beverages
   • Increase fiber intake
   • Focus on complex carbohydrates with lower glycemic index 1

2. Reduce Dairy Consumption:

   • Particularly limit or eliminate low-fat and skim milk
   • Consider dairy alternatives like almond, oat, or soy milk 2, 1

3. Increase Anti-Inflammatory Foods:

   • Incorporate foods high in antioxidants (colorful fruits and vegetables)
   • Add nuts, seeds, and green tea to help reduce oxidative stress 1

4. Avoid Specific Triggers:

   • Limit whey protein supplements, which have insulin-promoting properties 1
   • Reduce consumption of fatty and sugary products 5

Important Considerations

• Results from dietary modifications typically take 10-12 weeks to become apparent 1, 3
• Dietary changes should complement, not replace, conventional acne treatments 1
• The American Academy of Dermatology advises against self-prescribed supplements due to limited safety and efficacy data 1
• Evidence for dietary modification is stronger for patients with treatment-resistant acne or acne that worsens with specific food consumption 1

Pitfalls and Caveats

• Individual responses to dietary changes may vary
• The relationship between diet and acne remains somewhat controversial, with more research needed on specific nutrients 6
• Dietary intervention alone may not be sufficient for severe acne cases
• Patients should be cautioned against extreme dietary restrictions that could lead to nutritional deficiencies
• The necessary dietary changes may be challenging as they oppose typical Western diet patterns 4

By addressing these dietary factors, particularly glycemic load and dairy consumption, patients with hormonal acne may experience significant improvements in their skin condition while also potentially benefiting their overall health.
