Psoriasis (commonly known as psoriasis) is a chronic, immune-mediated inflammatory skin disease that cannot be cured, but a scientific lifestyle and a reasonable diet play a crucial role in controlling the condition, reducing recurrences, and improving quality of life. As a dermatologist, I recommend patients manage comprehensively from the following two aspects:

1. Lifestyle precautions

Avoid skin irritation and trauma

Do not scratch, scrub, or rub lesions forcefully to prevent the "isomorphic response" (Koebner phenomenon) — that is, the appearance of new lesions at injured sites.

Wear soft, breathable cotton clothing and avoid friction from synthetic fibers.

Maintain moisturizing care

Apply a fragrance-free, hypoallergenic emollient at least twice daily (e.g., containing ceramides, urea, or petroleum jelly), especially within 5 minutes after bathing; this helps repair the skin barrier and relieve itching and scaling.

Manage stress and emotions

Psychological tension, anxiety, and sleep deprivation are clear triggers. It is recommended to regulate emotions through a regular routine, moderate exercise (such as walking, yoga), meditation, or psychological counseling.

Quit smoking and limit alcohol

。

Smoking and alcohol consumption (especially beer) significantly worsen the condition and reduce treatment effectiveness. Complete abstinence from alcohol and smoking is strongly recommended.

Moderate sun exposure, avoid excessive sun

Mild sunlight (before 9 AM / after 4 PM) helps improve lesions, but sunburn must be avoided. Use physical sun protection when going outdoors (hats, parasols), and use a mild sunscreen when necessary.

Prevent infection

Streptococcal pharyngitis often triggers guttate psoriasis. Maintain oral hygiene and seek medical attention promptly if sore throat occurs.

2. Dietary regulation principles (anti-inflammatory, balanced, individualized)

✅ Recommended to eat more:

Deep-sea fish: salmon, mackerel, sardines (rich in omega-3, anti-inflammatory)

Fresh fruits and vegetables: spinach, broccoli, blueberries, carrots (rich in antioxidants)

Whole grains: oats, brown rice, quinoa (stabilize blood glucose, high fiber)

Healthy fats: olive oil, avocado, nuts (Mediterranean dietary pattern recommended)

High-quality protein: tofu, eggs, skinless poultry

⚠️ It is recommended to restrict or avoid:

Alcohol: all types may trigger or exacerbate the condition

High-sugar, high-fat processed foods: cakes, milk tea, potato chips, fried foods

Red meat and processed meat products: sausages, bacon, ham (contain pro-inflammatory fats and additives)

Some patients should observe whether they are sensitive to Solanaceae: such as tomatoes, eggplant, peppers (large individual differences, no need for blind avoidance)

Special reminder:

Weight control: obese patients have more severe disease and poorer treatment response. A 5%–10% weight loss can significantly improve symptoms.

No need for extreme food restrictions: unless a food is clearly identified as a trigger, a balanced diet is more important. Keeping a "diet-lesion diary" can help identify triggers.

Drink more water: 1500–2000 ml daily to maintain skin hydration.

✅ Doctor's summary:

Psoriasis management = standardized treatment + scientific care + healthy lifestyle + reasonable diet.

Although lifestyle and diet cannot replace medication, they are the "invisible pillars" for long-term disease stability.

By maintaining a gentle, regular, anti-inflammatory lifestyle, you can fully coexist with psoriasis while enjoying confidence and a high quality of life.

If you have concomitant arthritis, metabolic syndrome, or are receiving systemic therapy, please develop a personalized plan under the guidance of your physician or nutritionist. Do not trust “folk remedies or dietary taboos” blindly; scientific management is the correct approach.
