Cold sores are uncomfortable, but the right diet can make a big difference. Some foods can trigger outbreaks, while others help you heal faster and boost immunity.
🚫 Foods to Avoid
Avoid foods high in arginine, which the herpes virus uses to multiply.
High-Arginine Foods:
| Chocolate 🍫 | Nuts & seeds (almonds, peanuts, sunflower seeds) |
| Whole grains (oats, brown rice, whole wheat) | Gelatin & collagen |
| Protein bars or shakes with arginine |
Also, avoid acidic and salty foods that can irritate your lips or open blisters:
| Citrus fruits, tomatoes, vinegar, pickles, and spicy foods | Chips and salty snacks |
💡 Tip: Stick to soft, mild foods while the sore heals.
✅ Foods to Eat
Focus on Lysine-rich foods and nutrients that help fight the virus and repair skin.
Lysine-Rich Foods:
| Fish (salmon, cod, sardines) | Chicken, turkey, and eggs |
| Yogurt, milk, and cheese | Legumes (lentils, beans) |
Immune-Boosting & Healing Foods:
| Garlic and onions 🧄 | Leafy greens 🥬 |
| Berries and citrus alternatives 🍓 | Honey and propolis 🍯 |
| Green tea 🍵 |
💧 Hydration is key — water and herbal teas help your body recover.
