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
