From the Research
During an oral herpes outbreak, it's crucial to limit your intake of the amino acid arginine while increasing lysine consumption to potentially reduce the severity and duration of the outbreak. Arginine can promote herpes simplex virus replication, potentially worsening or prolonging outbreaks. Foods high in arginine that you should avoid include nuts (especially almonds, Brazil nuts, and walnuts), chocolate, oats, wheat germ, sesame and sunflower seeds, and gelatin. Instead, focus on consuming more lysine-rich foods like dairy products, fish, chicken, beef, eggs, and legumes, as lysine may help inhibit viral replication by competing with arginine. Some people find taking lysine supplements (typically 1000-3000 mg daily during outbreaks) helpful, though you should consult with a healthcare provider before starting any supplement regimen. This dietary adjustment works because the herpes virus requires arginine for replication, while lysine competitively inhibits arginine's availability to the virus. Key points to consider:
- Limit arginine intake from foods like nuts, chocolate, and oats
- Increase lysine consumption from foods like dairy, fish, and legumes
- Consider lysine supplements, but consult a healthcare provider first
- Remember that dietary changes should complement, not replace, conventional treatments like antiviral medications for managing herpes outbreaks, as discussed in studies like 1.
