It affects millions of people worldwide and is believed to be linked to immune system dysfunction. While treatments focus on managing symptoms, new research suggests that diet may play a crucial role in psoriasis severity.
New Research Highlights Dietary Impact
A study from King’s College London found that individuals with low adherence to the DASH diet and the Healthy Plant-Based Diet Index reported higher psoriasis severity. This suggests that dietary choices could influence symptom management.
The DASH diet (Dietary Approaches to Stop Hypertension) was originally designed to lower blood pressure and focuses on:
-
- Fruits and vegetables
- Whole grains
- Low-fat dairy
- Lean meats
- Limited salt, sugar, and saturated fats
Similarly, a Healthy Plant-Based Diet prioritises:
- Fruits and vegetables
- Whole grains
- Nuts and seeds
- Legumes
- Healthy plant oils
- Limiting animal-based foods, sugary items, and refined starches
Potential Benefits for Psoriasis Management
“Our findings point to the potential benefits of dietary interventions in improving patient outcomes,” said Sylvia Zanesco, a PhD student at King’s College London. “Given the impact of psoriasis on physical and psychological well-being, incorporating dietary assessments into routine care could offer patients additional support in managing their condition.”
Sample Daily Plant-Based DASH Diet
Breakfast: Avocado toast with poached egg, sundried tomatoes, whole-wheat toast, plus coffee, tea, or water and a piece of fruit.
Lunch: Hummus plate with red capsicum, cucumber, baby carrots, falafel patties, and a whole-grain pita pocket with water.
Dinner: Stir-fry with brown rice, vegetables, and chicken or salmon.
Snacks: Fruit, nuts, and yogurt.
While psoriasis management often involves medical treatments, this research highlights how nutrition may be an additional tool for improving symptoms. A diet rich in whole, plant-based foods could offer benefits not just for psoriasis but for overall health.
