About Parmesan Cheese
Parmesan cheese is a type of cheese that is aged for at least a year. It is made from cow’s milk and has a hard, granular texture. It has a rich, nutty flavor.
Parmesan cheese is a good source of protein, calcium, and phosphorus. It also contains vitamin A, B12, zinc, and selenium. Parmesan cheese has less lactose than some other cheeses.
Lysine Considerations
Lysine, a important amino acid, is required by the body to synthesize proteins and bolster the immune system.
Lysine has the potential to prevent or treat cold sores, which are blisters caused by the HSV-1 virus, also known as herpes.
Lysine operates by inhibiting the proliferation of HSV-1, which relies on another amino acid, arginine, to reproduce and infect cells. Lysine can only be acquired through our diet and is present in different high-protein foods such as eggs, dairy products, fish, meat, and poultry.
Parmesan cheese has a very high amount of lysine, which can provide about 480% of the RDI for an adult. Lysine can help the body prevent anemia, support bone health, and regulate cholesterol levels.
Arginine Considerations
Arginine is a essential amino acid that the human body uses to build proteins.
Arginine has multiple functions in the body, including wound healing, helping the kidneys remove waste products from the body, and maintaining immune and hormone function.
Arginine also plays a role in the replication of the herpes virus, making it a key factor in cold sore outbreaks. The herpes virus requires arginine to grow, replicate, and create new herpes viruses. Foods rich in arginine, such as nuts and chocolate, may increase the frequency and severity of these outbreaks.
Parmesan cheese has a high amount of arginine, which can provide about 152% of the RDI for an adult. Arginine can help the body improve insulin sensitivity, enhance memory, and promote wound healing.
Lysine-Arginine Ratio Analysis
Lysine and arginine are two amino acids that have different roles in the body and in the herpes simplex virus infection.
The herpes simplex virus, which causes oral and genital herpes, needs arginine to multiply and infect cells.
Lysine, on the other hand, can interfere with the absorption of arginine in the intestine, and thus limit the availability of arginine for the virus.
By eating a diet higher in lysine than arginine, one may be able to prevent or treat herpes flare ups.
Foods that have a high lysine-arginine ratio include dairy, fish, poultry, fruits, and vegetables. These foods can supply the body with sufficient lysine to compete with arginine and inhibit the virus from replicating and causing flare ups.
Because Parmesan Cheese contains much higher levels of lysine than arginine, it is highly recommended for people who suffer from herpes, as it may prevent outbreaks.
Parmesan cheese has a high lysine-arginine ratio, which can help protect against HSV infections. However, some people may experience weight gain or cardiovascular issues.
Nutrient Density & Portion Control
Nutrient density is a measure of how rich a food is in amino acids relative to portion size. We calculate it as (Lysine + Arginine) / 100, which gives you a quick sense of how much total amino acid content is packed into each 100g serving.
Parmesan Cheese has a high nutrient density (46.79), meaning it contains substantial amounts of both lysine and arginine. While this makes it nutrient-rich, it also means you should be more mindful of portion sizes when managing herpes. Consider consuming it in smaller, measured portions and balance it with other foods to maintain a favorable lysine-arginine ratio overall.
💡 Tip: Use the density metric to quickly gauge portion control. High-density foods are nutrient-dense and should be enjoyed mindfully, while low-density foods give you more flexibility in serving sizes.
Dietary Considerations for Herpes Management
Category Overview
Like other dairy products, cheese is a decent source of lysine and poor in arginine. Cheese can help boost the immune system and fight off herpes infections. Cheese also contains calcium, protein, and vitamin B12, which are essential for overall health. Parmesan Cheese, ricotta cheese, cottage cheese, and cheddar cheese are some of the cheeses that have the most lysine compared to arginine.Practical Recommendations
Besides consuming foods with a high ratio of lysine to arginine, you should also follow some other dietary tips to cope with herpes outbreaks. For example:
Eating a balanced and nutritious diet that supports your immune system and reduces inflammation. This means consuming plenty of fruits, vegetables, whole grains, lean protein, and healthy fats, and avoiding processed foods, added sugars, alcohol, and caffeine.
Avoid alcoholic beverages and caffeine which can overstimulate your body, leave you dehydrated, and compromise your immune system.
L-lysine supplements can help you prevent herpes outbreaks and stop a cold sore before it develops by depriving the virus of arginine, which it needs to form a cold sore.
Taking other food supplements that can improve your immunity and protect your cells from oxidative stress, such as vitamin C, zinc, selenium, and antioxidants.
Avoiding foods that can cause allergic reactions or sensitivities, such as gluten, dairy, nuts, eggs, or shellfish. These foods can trigger inflammation and weaken your immune system, making you more susceptible to outbreaks.
Pain, swelling, and itching can be reduced by eating foods that have anti-inflammatory, antiviral, and antibacterial properties, such as honey, plain yogurt, aloe vera, and chamomile tea. These foods can also help you heal faster by promoting tissue repair.
Is Parmesan Cheese Safe for Shingles?
Yes, Parmesan Cheese is an excellent choice for shingles management. With a lysine-to-arginine ratio of 2.51, this food is rich in lysine, which supports your body's natural defenses against varicella-zoster virus (VZV) reactivation.
Lysine is known to inhibit arginine metabolism, a key factor in viral replication. By choosing lysine-rich foods like Parmesan Cheese, you're actively supporting your immune system's ability to keep VZV dormant.
Include Parmesan Cheese regularly in your diet to maintain a lysine-favorable amino acid balance. Pair it with other lysine-rich foods for maximum antiviral support.
✓ Shingles-Friendly: This food's high lysine content makes it a smart choice for reducing herpes zoster reactivation risk.

Is Parmesan Cheese high in arginine?
Parmesan Cheese contains 1332.14mg of arginine per 100g serving. This is considered relatively high. If you're managing herpes, monitor your intake of high-arginine foods.
Can I eat Parmesan Cheese if I have herpes?
Yes, you can eat Parmesan Cheese. However, the key is understanding its lysine-arginine ratio (2.51) and balancing it with lysine-rich foods. Consult with a healthcare provider about your specific dietary needs.
What is the lysine-arginine ratio of Parmesan Cheese?
The lysine-arginine ratio of Parmesan Cheese is 2.51. A ratio above 1 generally favors lysine. This ratio helps determine how suitable it is for herpes management.
