About Beets
Beets are a type of root vegetable that have a dark red, purple, or yellow color. They have a sweet, earthy flavor and a crunchy texture.
Beets are a good source of folate, manganese, and potassium. They also contain fiber, antioxidants, and nitrates. Beets can help lower blood pressure, improve endurance, and support liver health.
Lysine Considerations
From a nutritional standpoint, lysine is one of the most studied amino acids in relation to herpes management. A landmark study published in Dermatologica found that supplemental lysine significantly reduced the frequency, severity, and healing time of cold sore outbreaks in participants who took at least 1,000mg daily.
Lysine's mechanism is competitive inhibition: because it shares the same intestinal absorption pathway as arginine, higher dietary lysine levels limit how much arginine becomes available to the herpes virus. For people managing HSV-1 or HSV-2, tracking the lysine content of foods — not just avoiding high-arginine foods — gives a more complete and proactive picture of dietary management.
Beets have a low amount of lysine, which can provide about 8% of the RDI for an adult. Lysine can help the body fight infections, support muscle growth, and regulate appetite.
Arginine Considerations
Arginine is a semi-essential amino acid that our body can use to make nitric oxide, a molecule that improves blood circulation, cellular communication, and energy production.
Arginine has a variety of benefits for our health and performance, such as lowering blood pressure, enhancing wound healing, and increasing exercise endurance.
Arginine can also affect the herpes virus, which causes cold sores and genital herpes. Studies suggest that arginine may help the virus grow and cause outbreaks, so people with herpes may want to avoid foods that are high in arginine or take lysine supplements to block its effects.
Beets also have a low amount of arginine, which can provide about 3% of the RDI for an adult. Arginine can help the body produce creatine, improve exercise performance, and enhance sexual 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 Beets contains much higher levels of lysine than arginine, it is highly recommended for people who suffer from herpes, as it may prevent outbreaks.
Beets have a moderate lysine-arginine ratio, which can help prevent or treat HSV infections. However, some people may experience kidney stones or urine discoloration from consuming too much beets.
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.
Beets has a low nutrient density (0.75), which means it contains relatively lower amounts of these amino acids. You can safely enjoy larger portions of this food without worrying as much about amino acid balance, making it a flexible option in your herpes management diet.
💡 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
Most vegetables are not very high in in calories and high in in vitamins, minerals, and antioxidants. Many vegetables have more lysine than arginine, such as beets, turnips, tomatoes, soybean sprouts, potatoes, celery, sweet potatoes, summer squash, and green beans. These vegetables can help prevent or treat herpes outbreaks, as lysine can suppress the herpes virus. Other vegetables have more arginine than lysine, such as peas, carrots, broccoli, cauliflower, and mushrooms. These vegetables can still be consumed in moderation, as they have other health benefits.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.
Avoid alcoholic beverages and caffeine which can overstimulate your body, leave you dehydrated, and compromise your immune system.
Consider taking l-lysine supplements, which can help prevent herpes outbreaks and stop a cold sore before it emerges by limiting the availability of arginine for the virus, which it requires to produce 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.
Foods that can boost your immunity and fight inflammation are essential to prevent outbreaks. Honey, plain yogurt, aloe vera, and chamomile tea are some examples of these foods. They can also soothe your symptoms and help you recover quicker by reducing pain, swelling, and itching.
Is Beets Safe for Shingles?
Yes, Beets is an excellent choice for shingles management. With a lysine-to-arginine ratio of 2.40, 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 Beets, you're actively supporting your immune system's ability to keep VZV dormant.
Include Beets 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 Beets good or bad for herpes?
With a ratio of 2.40, Beets is considered a lysine-dominant food — a positive choice for herpes management. 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. Beets fits into the favourable category.
Is Beets high in arginine?
Beets is relatively low in arginine at 22.06mg per 100g. This level is manageable for most people when consumed as part of a balanced, lysine-rich diet.
How much lysine does Beets contain?
Its lysine content of 52.94mg per 100g is low, so it contributes little lysine to counterbalance arginine from other foods. Because its lysine content exceeds its arginine content, Beets contributes positively to the overall amino acid balance in a herpes management diet.
Can I eat Beets if I have herpes?
Yes — Beets has a lysine-to-arginine ratio of 2.40, 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 Beets?
The lysine-arginine ratio of Beets is 2.40, calculated from 52.94mg lysine and 22.06mg arginine per 100g serving. A ratio above 1 means lysine is the dominant amino acid, which is generally favourable for herpes management.
Does Beets trigger cold sores?
Beets is unlikely to trigger cold sores on its own. Its lysine-to-arginine ratio of 2.40 means it does not provide an excess of arginine that would feed the herpes simplex virus. If you notice a personal correlation between eating Beets and outbreaks, consider reducing your serving size.
