Treat psoriasis: Kim Kardashian avoids acidic vegetables like tomatoes. In Germany alone, an estimated two million people suffer from the skin disease.

Psoriasis flares up after a phase with no or mild symptoms. An anti-inflammatory diet has been proven to help counteract these flare-ups. High-quality vegetable oils such as cold-pressed linseed oil and wheat germ oil are also said to have anti- inflammatory properties because they contain omega-3 fatty acids. Since sugar can promote inflammation, those affected should choose low-sugar varieties of fruit and vegetables.
