About Pastrami
Pastrami is a type of meat that is made from beef, turkey, or other meat that is brined, smoked, and seasoned with spices.
Pastrami is high in protein, iron, zinc, and vitamin B12. It can help build muscle, prevent anemia, and support nerve function. However, it is also high in fat, sodium, and cholesterol, which can increase the risk of heart disease, hypertension, and stroke.
Lysine Considerations
Lysine is a conditionally essential amino acid that plays a central role in how your body handles the herpes simplex virus. At the cellular level, lysine and arginine compete for the same transporters to enter cells — meaning a higher intake of lysine effectively crowds out the arginine that HSV-1 and HSV-2 depend on to replicate.
Beyond its antiviral competition with arginine, lysine also contributes to immune resilience. It supports the production of antibodies, promotes collagen synthesis for skin barrier integrity, and helps regulate cortisol — the stress hormone known to trigger outbreaks. Foods rich in lysine are therefore doubly beneficial: they supply the nutrient directly while also supporting the immune pathways that keep the virus dormant.
Pastrami has a very high amount of lysine, an essential amino acid that is important for protein synthesis, collagen formation, and calcium absorption.
Arginine Considerations
Arginine is an amino acid that our body needs to make nitric oxide, a molecule that helps with blood circulation, energy, and communication between cells.
Arginine can promote your health and performance, such as lowering your blood pressure, healing your wounds, and boosting your exercise endurance.
Arginine can be made by your body or obtained from foods like meat, dairy, nuts, and soy.
Unfortunately, the herpes virus is known to "feed" on arginine, and having a diet higher in arginine than lysine may increase the occurrence and severity of cold sores and herpes outbreaks.
Pastrami has a very high amount of arginine, a semi-essential amino acid that is involved in nitric oxide production, wound healing, and immune function.
Lysine-Arginine Ratio Analysis
The ratio of lysine to arginine in a food item indicates the amount of these amino acids it contains. Lysine and arginine are both necessary for protein synthesis and other metabolic processes.
However, they have different effects on the herpes simplex virus, which causes cold sores and genital herpes. Lysine can inhibit the replication of the virus, while arginine can stimulate it.
Eating foods with a higher lysine-arginine ratio may help lessen the occurrence and severity of herpes outbreaks.
Examples of foods with a high lysine-arginine ratio include dairy, fish, poultry, fruits, and vegetables. These foods can provide the body with enough lysine to compete with arginine, potentially reducing the risk of viral replication.
Because Pastrami contains slightly more lysine than arginine, increasing its consumption may benefit people who suffer from herpes, as it may boost the immune system.
Pastrami has a favorable lysine-arginine ratio, which means that it has more lysine than arginine. This may help prevent or treat viral infections, such as herpes simplex virus, by inhibiting the replication of the virus.
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.
Pastrami has a medium nutrient density (24.18), which is a good balance. You can enjoy this food in moderate portions without needing to be overly restrictive. It's a solid choice for herpes management when paired with other lysine-rich foods.
💡 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
Red meats are a great source of protein and lysine but they also contain more fat and cholesterol than poultry or fish. Red meats can help prevent or treat herpes outbreaks as lysine can block the activity of arginine. Red meats also contain zinc iron and vitamin B12 which are essential for immune function and nerve health. Beef and pork are some of the red meats that have more lysine than arginine with almost as much as poultry. Despite this red meats should be consumed in moderation as they can increase the risk of cardiovascular diseases and some cancers.Practical Recommendations
In addition to eating foods that have a high lysine-arginine ratio, there are other dietary recommendations that can help you manage herpes outbreaks. For instance:
A well-balanced and healthy diet that strengthens your immune system and lowers inflammation is important. This means you should eat a lot of fruits, vegetables, whole grains, lean protein, and good fats, and avoid processed foods, added sugars, alcohol, and caffeine.
Stay well hydrated throughout the day. Dehydration stresses the body and can raise cortisol levels, which is a documented trigger for HSV reactivation. Aim for at least 1.5–2 litres of water daily, and compensate with extra fluid intake after exercise, in hot weather, or when consuming diuretics like coffee or alcohol.
You may want to take l-lysine supplements. L-lysine is known to prevent herpes outbreaks and it can help stop a cold sore in its initial stages by "starving" the virus of arginine before it has a chance to cause 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.
To prevent outbreaks, avoid foods that can cause allergic reactions or sensitivities, such as gluten, dairy, nuts, eggs, or shellfish. These foods can harm your immune system and make inflammation worse.
Eating foods that can soothe your symptoms and speed up your healing process, such as honey, plain yogurt, aloe vera, and chamomile tea. These foods have anti-inflammatory, antiviral, and antibacterial properties that can reduce pain, swelling, and itching, and promote tissue repair.
Is Pastrami Safe for Shingles?
Yes, Pastrami is generally safe for shingles management. With a lysine-to-arginine ratio of 1.24, this food maintains a relatively balanced profile.
While it doesn't strongly favor lysine, it won't actively trigger viral reactivation either. Its balanced profile means it can fit comfortably into a shingles-aware diet without major restrictions. The key is pairing Pastrami with other lysine-rich foods to maintain overall dietary balance.
Enjoy Pastrami as part of a well-rounded diet. Consider combining it with lysine-rich proteins to shift your overall amino acid balance in your favor.
○ Moderately Safe: This food is fine to eat regularly, especially when balanced with lysine-rich options.

Is Pastrami good or bad for herpes?
With a ratio of 1.24, Pastrami sits in a neutral range. It is unlikely to cause problems in moderate servings when overall diet is lysine-rich. The lysine-to-arginine ratio is the key metric: foods above 1.0 generally support herpes management, while foods below 1.0 require more careful portioning. Pastrami fits into the favourable category.
Is Pastrami high in arginine?
At 1078.57mg per 100g, Pastrami has a notably high arginine content. For context, foods above 200mg arginine per 100g are worth monitoring closely if you have frequent herpes outbreaks. Pairing Pastrami with high-lysine foods like eggs, fish, or dairy can help offset its arginine content.
How much lysine does Pastrami contain?
Its lysine content of 1339.29mg per 100g is substantial and actively helps compete with arginine at the intestinal absorption level. Because its lysine content exceeds its arginine content, Pastrami contributes positively to the overall amino acid balance in a herpes management diet.
Can I eat Pastrami if I have herpes?
Yes — Pastrami has a lysine-to-arginine ratio of 1.24, which is favourable for people managing HSV-1 or HSV-2. It can be enjoyed as part of a herpes-conscious diet without significant concern. Always consult your healthcare provider for personalised advice.
What is the lysine-arginine ratio of Pastrami?
The lysine-arginine ratio of Pastrami is 1.24, calculated from 1339.29mg lysine and 1078.57mg arginine per 100g serving. A ratio above 1 means lysine is the dominant amino acid, which is generally favourable for herpes management.
Does Pastrami trigger cold sores?
Pastrami is unlikely to trigger cold sores on its own. Its lysine-to-arginine ratio of 1.24 means it does not provide an excess of arginine that would feed the herpes simplex virus. If you notice a personal correlation between eating Pastrami and outbreaks, consider reducing your serving size.
