A new study suggests that adhering to a Mediterranean diet relieve the severity of psoriasis, its inflammatory conditions on the skin, and slow its progression. Its high content of monounsaturated fats (which are found in olive oil and other plant oils), high levels of antioxidants and polyphenols (found in fruits and vegetables), and high content of fiber (from vegetables or wholegrain cereals) may all be responsible for the diet’s anti-inflammatory properties.
