4 foods to avoid for people with cold sores

Cold sores or fever blisters are common skin conditions wherein people develop small, liquid-filled blisters on and around their lips or other areas. These blisters are caused by herpes simplex virus type 1 (HSV-1) or herpes simplex virus type 2 (HSV-2). Usually, cold sores are contagious and can be controlled through treatment. However, certain foods can worsen symptoms in individuals. Here are some foods that are best avoided while managing cold sores. Peanuts Nuts are among the biggest triggers of cold sores as they contain a large amount of arginine. This chemical causes flare-ups and worsens cold sores in people with the condition.
