As we know, being overweight can increase our risk of a variety of conditions. Emerging evidence shows that obesity seems to affect several features of Psoriatic Arthritis (PsA), such as its development, cardiovascular risk and clinical outcome. A link between increased BMI in early adulthood and the risk of PsA development in psoriatic patients has been found, supporting a link between fat-mediated inflammation and joint involvement. Abdominal obesity may also increase the risk of disease activity in PsA patients (Russollilo, 2013).
A recent paper by Di Minno (2013) determined that even 5% loss of body weight can improve the chances of minimising disease activity. This is further improved with 10% loss of body weight.
What does this mean for our clients with PsA? Addressing any weight issues is imperative, which more often than not can be assisted by making dietary changes. Ensuring plenty of vegetables, nuts and legumes are included, choosing adequate portions and avoiding processed, high energy, refined options as much as possible can make a real difference. I have written posts about reducing inflammation with food, which you can find here and here.
