Does Your Diet Affect Herpes? Foods You Should Eat or Avoid

Many people living with herpes – both HSV-1 and HSV-2 – wonder if diet can play a role in outbreaks. And the short answer is: Yes, it can to some extent. While herpes cannot be cured with diet, research and experience suggest that certain foods can worsen or reduce outbreaks.

 

In this blog post, you will get an overview of how diet and nutrition are related to herpes – and which foods you should consider eating more of – or avoiding.

Lysine and arginine – amino acids with importance

The two amino acids L-lysine and L-arginine play a central role in the activity of the herpes virus in the body:

• Arginine promotes the virus's ability to multiply
• Lysine counteracts this process and can help inhibit outbreaks

A diet with more lysine and less arginine can therefore – according to several studies and user reports – be beneficial.

Foods you should prioritize (rich in lysine):

• Chicken and turkey
• Fish and seafood
• Eggs
• Yogurt and dairy products
• Beans and lentils
• Potatoes and vegetables with low sugar content
• Avocado and mango

Tip: Consider L-lysine as a dietary supplement – Ask your doctor or therapist about the right dosage.

Foods you should limit (rich in arginine):

• Chocolate
• Nuts and almonds
• Peanuts and peanut butter
• Oatmeal
• Wheat germ and whole grains in large quantities
• Gelatin and certain protein supplements

This doesn't mean you should never eat these foods – but be aware if you experience breakouts shortly after consuming them.

Foods that strengthen the immune system

A strong immune system is the key to keeping herpes at bay. Eat:

• Broccoli and green vegetables
• Citrus fruits (vitamin C)
• Fatty fish (omega-3 + vitamin D)
• Berries (antioxidants)
• Garlic (antiviral properties)

Foods and drinks you should be careful with

Sugar and alcohol
These can weaken the immune system and increase the risk of outbreaks.

Caffeine in large quantities
Excessive consumption of coffee and energy drinks can stress the body.

Is diet enough to prevent herpes outbreaks?

No – diet is a supplement, not a replacement for medical treatment or lifestyle strategies like sleep and stress reduction. But for many, small changes in diet can make a noticeable difference in how frequent and severe flare-ups are.

Conclusion

Your diet can affect how herpes behaves in your body. By increasing lysine and decreasing arginine, supporting your immune system, and avoiding sugar and alcohol, you give your body the best conditions to keep the virus at bay.
