A study published in 2025 investigated the relationship between dietary patterns and psoriasis severity. Researchers at King's College London analyzed data from a cohort of individuals with psoriasis, examining their eating habits and disease activity over time. The findings suggest that those who adhered to a plant-rich, low saturated-fat diet experienced reduced psoriasis severity compared to those following other dietary patterns.
The researchers propose several potential mechanisms by which this dietary pattern may exert its beneficial effects on psoriasis. For example, plant-based foods are rich in antioxidants and polyphenols, which have anti-inflammatory properties that could help reduce inflammation associated with psoriasis. Additionally, a low saturated-fat diet may promote improved gut health, which is also thought to play a role in the development and progression of psoriasis.
While this study suggests an association between dietary patterns and psoriasis severity, further research is needed to fully understand the relationship and to determine whether such diets can be recommended as a therapeutic approach for individuals with psoriasis.
