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. Among nuts, peanuts and hazelnuts contain the largest reserves of this chemical, and, therefore, they must not be eaten when dealing with cold sores. Additionally, peanut butter must be avoided entirely for two to three weeks, the normal lasting period for cold sores.

Oranges
Citrus fruits are another big no-no when it comes to foods to eat when one is coping with cold sores. Oranges and grapefruits are known for their citrus-filled refreshing flavor; therefore, one must avoid them at all costs. Such fruits contain an acidic element that will cause pain and a burning sensation when they get into contact with a cold sore blister. Now, citrus fruits may be a significant part of some people’s daily meals. So, instead of eating oranges or grapefruits, one can replace them with alternatives such as cucumbers, bananas, or grapes to satiate their sweet cravings.

Pizza
Processed foods are terrible for the body in multiple ways. They cause inflammation and, as a result, worsen cold sores in individuals. Eating a pizza involves opening the mouth wide to bite into a slice. However, opening the mouth that wide may cause the blisters to split open. For these reasons, one must avoid pizza and other processed foods during this phase.

Jalapeño
Ultra-spicy and hot foods make cold sores ten times worse in people with the condition. Therefore, spice lovers will need to keep themselves away from their beloved jalapeños until their cold sores go away. Spicy foods cause irritation and discomfort as they can reopen cold sores and worsen them. Additionally, such foods are known to increase body heat and, as a result, worsen cold sores in people.
