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 an important amino acid that the body needs to make proteins and support your immune system.
Lysine can help prevent or treat cold sores, which are blisters caused by the virus HSV-1, also known as herpes.
Lysine works by blocking the growth of HSV-1, which needs another amino acid called arginine to multiply and infect cells. Lysine can only be obtained through diet, and can be found in many abundant in protein foods like milk, cheese and yogurt, fish, eggs, meat, and poultry.
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
While arginine is essential for healthy blood vessel function and plays a role in releasing growth hormone, it has an unfortunate interaction with the herpes simplex virus. HSV hijacks the arginine transport system in nerve and epithelial cells to stockpile the amino acid it needs for viral DNA synthesis and protein production.
Interestingly, the relationship is not purely about total arginine intake — it is about the ratio relative to lysine. A food can be moderately high in arginine and still be well-tolerated if its lysine content is proportionally higher. This is why the lysine-to-arginine ratio shown on this page is a more useful guide than looking at arginine content in isolation.
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
Understanding the lysine-arginine ratio means understanding why some otherwise healthy foods can still be problematic for HSV management. A food can be nutritious, low in calories, and full of vitamins — yet if its arginine content substantially outweighs its lysine content, regular consumption may tip your internal amino acid balance in favour of the virus.
The ratio shown on this page is calculated from USDA nutritional data per 100g of food. A ratio above 1.5 is generally considered favourable for herpes management; between 0.75 and 1.5 is neutral territory where overall diet context matters more; below 0.75 means the food has noticeably more arginine than lysine, and portion size becomes an important consideration. Use this as one data point among many, and pair it with the density score to get a complete picture.
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 decent 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:
Prioritising anti-inflammatory whole foods — leafy greens, colourful vegetables, legumes, and omega-3-rich fish — gives your immune system the micronutrients it needs to keep HSV dormant. Chronic low-grade inflammation is a known trigger for viral reactivation, so reducing dietary sources of inflammation is a direct outbreak-prevention strategy.
Make sure to drink plenty of water to keep yourself hydrated and eliminate toxins from your body. Water can also help you avoid dryness and irritation of the skin and mucous membranes, which can lead to outbreaks.
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.
Pay attention to your personal food triggers beyond the lysine-arginine framework. Some people with HSV notice that highly processed foods, refined sugars, or specific allergens reliably precede outbreaks. Keeping a simple food and symptom journal for a few weeks can reveal individual patterns that no general chart can capture.
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.
