Introduction
Patients with lupus erythematosus should pay attention to their diet by avoiding photosensitive foods, supplementing high-quality protein, limiting spicy and irritating foods, restricting high-sodium intake, and ensuring a balanced intake of vegetables and fruits. If symptoms such as widespread worsening of skin rashes or generalized edema occur, prompt medical evaluation and treatment at a hospital are recommended.

Lupus patients should pay attention to several dietary considerations: avoiding photosensitizing foods, supplementing high-quality protein, limiting spicy and irritating foods, restricting high-sodium intake, and ensuring balanced consumption of vegetables and fruits. If symptoms such as widespread worsening of skin rashes or generalized edema occur, prompt medical evaluation and treatment are strongly recommended.

1. Avoid photosensitizing foods: Certain foods increase skin sensitivity to light, potentially triggering or exacerbating skin erythema. Reduce daily intake of celery, cilantro, and figs. After consuming these foods, enhanced sun protection is essential to lower the risk of disease flare-ups.

2. Supplement high-quality protein: Due to increased metabolic demands, adequate protein intake is crucial for tissue repair. Include foods such as eggs, lean meats, freshwater fish, and milk to support muscle and organ function, improve overall nutritional status, and promote disease stability.

3. Limit spicy and irritating foods: Minimize consumption of highly stimulating ingredients such as chili peppers, Sichuan peppercorns, and raw garlic. These foods may intensify systemic inflammatory responses and irritate the gastrointestinal tract; GI discomfort can indirectly impair overall health and hinder disease control.

4. Restrict high-sodium diets: In cases of edema or renal involvement, avoid salt-preserved foods, pickled vegetables, and processed meats. Excessive sodium intake promotes water and sodium retention, worsening edema and increasing renal metabolic burden.

5. Ensure balanced vegetable and fruit intake: Consume a variety of fresh vegetables and fruits to meet daily vitamin requirements. Avoid over-reliance on any single food group; diverse dietary patterns help sustain normal metabolism and maintain optimal nutritional foundations.

Avoid unverified folk remedies or tonics without medical guidance. Maintain regular, portion-controlled meals. Abstain from smoking and alcohol. Tailor dietary choices according to individual organ function, avoid binge eating, and integrate healthy lifestyle habits to stabilize overall physical condition.
