Foods to Avoid During Cold Sore Outbreaks

Cold sores, or fever blisters, are caused by the herpes simplex virus, HSV-1. While there is no cure for cold sores or a method to prevent cold sores completely, certain dietary choices can help reduce the severity and frequency of outbreaks.

• Arginine-Rich Food
  Studies show that arginine may contribute to the spread of the herpes simplex virus by promoting the body’s ability to reproduce certain viruses, including the herpes virus.* Foods that contain arginine include flaxseeds, sunflower seeds, sesame seeds, chocolate, spinach, whole grains, almonds, pork, and turkey breast.
• Processed Food
  Because cold sores recur when the immune system is compromised, some foods may lead to recurrence of a cold sore. Avoid processed foods like sugary breakfast cereals, packaged snacks, frozen foods, canned foods, pasta meals and food high in saturated fats.
• Alcohol
  Alcohol consumption can weaken the immune system and trigger cold sore outbreaks by weakening your immune system.

A common trigger is a weakened immune system, so boosting the immune system during and prior to cold sore outbreaks may be effective in reducing cold sores:

• Zinc is a mineral that plays a crucial role in supporting the immune system and promoting wound healing. **Food high in Zinc: oysters, red meat
  
• Vitamin C is significant in supporting the immune system and promoting cold sore healing. It helps enhance the formation of leukocytes, vital to fighting off infections. Food high in Vitamin C: leafy greens, bell peppers
  
• The B vitamins play essential roles in the circulation of oxygen throughout the body and in reducing stress levels. Food high in Vitamin B: spinach, salmon
  
• While research is mixed, Lysine (amino acid) blocks arginine and may stop the virus from replicating. ***Foods high in Lysine: vegetables, legumes, milk, cheese
