A recent review published in Current Nutrition Reports highlights how the Mediterranean diet (MD) can support the treatment of chronic skin conditions like hidradenitis suppurativa (HS), psoriasis, and acne. Researchers found that this diet’s anti-inflammatory and antioxidant properties help reduce disease severity, lower metabolic risks, and improve overall patient outcomes.
The Mediterranean Diet and Skin Health
The Mediterranean diet is known for its beneficial effects on inflammation and overall health. It includes whole foods such as vegetables, fruits, whole grains, legumes, nuts, fish, and extra virgin olive oil while limiting processed foods and red meat. Key nutrients in the MD, including omega-3 fatty acids, polyphenols, and healthy fats, help reduce inflammation, support gut health, and regulate the immune system. These effects make MD a valuable dietary approach for managing inflammatory skin conditions.
How the Mediterranean Diet Affects Chronic Inflammatory Skin Conditions
Chronic skin conditions like HS, psoriasis, and acne cause both physical and mental distress. These conditions often share common inflammatory pathways, but each also has distinct characteristics. Psoriasis and HS are linked to immune system overactivation, while acne is tied to excess oil production and bacterial growth. Due to the chronic nature of these diseases, long-term management is required, and dietary changes can play a key role in improving symptoms.
Psoriasis Treatment
Studies suggest that the Mediterranean diet can help manage psoriasis by reducing inflammation and oxidative stress. Components like extra virgin olive oil and fish are linked to lower psoriasis severity. Research has shown that a diet high in these foods can help reduce levels of C-reactive protein (CRP) and improve Psoriasis Area and Severity Index (PASI) scores. These effects highlight the potential of MD as a complementary treatment for psoriasis. Although it cannot cure the condition, incorporating MD with conventional treatments could improve overall disease management.
Hidradenitis Suppurativa (HS) Treatment
The Mediterranean diet is also valuable for managing hidradenitis suppurativa, a chronic skin disease influenced by metabolic and hormonal factors. Studies have shown that patients with HS who adhere to the MD experience less severe symptoms. Research indicates that a preference for extra virgin olive oil and poultry over red meat helps reduce HS severity. MD helps regulate inflammation, balance gut microbiota, and reduce oxidative stress, all of which contribute to improved HS outcomes.
Acne Treatment
Acne, another common inflammatory skin condition, is affected by genetic, hormonal, and lifestyle factors. The Mediterranean diet may help reduce acne severity by lowering insulin-like growth factor-1 (IGF-1) levels, which influence sebum production. High adherence to the MD has been associated with a decrease in acne severity. This is in contrast to diets high in refined carbohydrates and unhealthy fats, which can worsen acne by increasing inflammation and promoting hormonal imbalances.
However, while some studies show the benefits of the Mediterranean diet for acne, further research is needed to develop clear dietary guidelines for acne prevention and treatment.
Conclusion
The Mediterranean diet offers a promising approach for managing chronic inflammatory skin conditions like psoriasis, acne, and hidradenitis suppurativa. Its antioxidant and anti-inflammatory effects, combined with its ability to regulate metabolic health, make it a valuable non-pharmacological treatment option. However, its effectiveness varies from person to person, and dietary plans should be personalized to suit individual needs and preferences.
Healthcare professionals can help patients by incorporating Mediterranean diet principles into a balanced nutritional plan. This approach, when combined with conventional treatments, may improve disease outcomes and support long-term skin health. Further research will help optimize dietary strategies for these skin conditions.
