Fever Blisters & Diet
-
Arginine
-
Fever blisters require the amino acid arginine to replicate. High levels of arginine are found in foods such as chocolate, nuts, beer, coffee, whole wheat and gelatin.
Lysine
-
Lysine is an amino acid that counteracts arginine. Foods with high lysine content include dairy products, most fruits and vegetables, and meats such as chicken and fish.
Significance
-
Eating foods with high levels of lysine and low levels of arginine can prevent or reduce the number of fever blister outbreaks an individual experiences.
Supplements
-
Dietary supplements can help prevent fever blisters and reduce the time a fever blister needs to heal. Lysine, zinc, B vitamins and vitamin C help cold sores heal faster. Supplements that contain gelatin, however, are counterproductive because gelatin can trigger an outbreak.
Liquids
-
Drinking lots of water can flush out the system and help a fever blister heal. Adding fresh lemon to water keeps arginine levels under control.
