The impact of dietary interventions in psoriatic arthritis

Abstract

Purpose of reviewPsoriatic arthritis (PsA) is a common form of inflammatory arthritis that affects people with psoriasis. Both psoriasis and PsA are associated with metabolic diseases including obesity, hypertension, hyperlipidaemia, diabetes mellitus, fatty liver disease, and cardiovascular disease including myocardial infarction. Dietary interventions for psoriatic disease have been of great interest, particularly among patients with PsA.Recent findingsHerein, we review the evidence for dietary intervention in psoriatic arthritis. To date, weight loss among patients who are obese has the greatest evidence for benefit. We also examine the evidence for fasting, nutrient supplementation, and specific diets as adjunct therapeutic strategies.SummaryWhile the data do not clearly support a single dietary intervention across the disease, weight loss among those who are obese results in improved PsA disease activity and physical function. Additional studies are needed to better understand the impact of diet on psoriatic arthritis.

Health benefits of exercise and dietary interventions for patients with psoriasis – a literature review

“…Additionally, a healthy diet and exercise regimen can also improve erectile dysfunction associated with psoriasis (46). Dietary intervention in psoriatic arthritis demonstrates the greatest evidence of benefit for weight loss among obese patients (47). A non-pharmacological, holistic approach may enhance the quality of life for individuals with psoriatic arthritis, incorporating dietary adjustments, adequate sleep duration, and physical activity (48).…”

Diet affects inflammatory arthritis: a Mendelian randomization study of 30 dietary patterns causally associated with inflammatory arthritis

“…Previous studies have reported that excessive consumption of red meat increases the risk of early-onset RA ( 17 ), and dietary fiber supplementation reduces the activity of the disease in patients with AS ( 18 ). However, it has been argued that several current cross-sectional studies, with limited sample sizes and confounding factors affecting the results, cannot be relied upon to conclude that there is a correlation between diet and IA ( 19 ). The causal associations between other dietary intake and the risk and severity of IA are currently unknown.…”
