5. Study Description
Brief Summary
Psoriasis (Ps) and psoriatic arthritis (PsA) are associated with increased risk of metabolic syndrome (MetS), body fatness and cardiovascular risk. Additionally, oxidative stress and inflammation are also contributing mechanisms on Ps and PsA. However, little is known about the influence of diet and micronutrients on the main outcomes of these diseases. The aim of the investigators is to evaluate the effectiveness of an intervention diet program on disease activity, metabolic profile and oxidative stress inpatients with Psoriasis and Psoriatic Arthritis.
