Inflammatory skin conditions like psoriasis may be brought on by a western diet high in fat and sugar, reveals a new study by UC Davis Health researchers. 

According to the study, which was written up in the Journal of Investigative Dermatology, dietary factors rather than obesity itself may be responsible for skin inflammation and the onset of psoriasis. Psoriasis is a common chronic skin condition that generates scales and red patches of skin that are irritating and occasionally painful.
