Anyone who has ever had a cold sore usually gets it once more and once more. Whenever the immune system is weakened, the painful blisters come back. However, the right diet can help reduce outbreaks or even prevent them altogether.
After an infection, herpesviruses remain dormant in nerve cells near the spinal cord, waiting for the immune system to weaken once more so they can strike once more. If you want to prevent this, you should strengthen your immune system and pay close attention to what he or she eats.

To stay healthy, humans need the amino acids lysine and arginine. The body needs lysine for cell division and wound healing, arginine improves fat burning, ensures performance and supports various functions of the immune system. However, it also promotes the multiplication of herpes viruses, which in turn is slowed down by lysine.
Avoiding or preferring certain foods can have positive effects
A balanced ratio between arginine or L-arginine and lysine is therefore desirable, whereby people who tend to cold sores avoid certain foods and prefer others.
Lysine is mainly found in animal foods such as eggs, red meat and fish, especially salmon, with tuna being an exception. Cow’s milk, Gouda, cottage cheese, Parmesan and low-fat quark also contain large amounts of the amino acid. Tofu and legumes such as chickpeas, lentils or beans remain for vegans.
Foods that in turn contain a lot of L-arginine and should therefore be avoided are, for example, the following:

For people who regularly struggle with cold sores, a permanent change in diet is recommended. But it can also help, at least temporarily, to avoid foods that are particularly rich in L-arginine. What also helps: Eat carbohydrates in the form of old types of grain such as spelt, einkorn or emmer, use high-quality vegetable oils from olives, walnuts or rapeseed, and eat a diet rich in vitamin C with lots of fruit and vegetables and drink enough fluids gain weight.
