Foods to Eat and Avoid When You Have Shingles

Shingles, a viral infection, arises from the reactivation of the varicella-zoster virus, the same pathogen responsible for chickenpox. It typically manifests as a painful rash and can affect individuals with weakened immune systems. While medical treatment is primary, dietary choices can support recovery and symptom management. A balanced diet helps bolster the body’s defenses, reduce inflammation, and promote overall well-being during a shingles outbreak.

Foundational Foods for Recovery

During a shingles outbreak, a balanced diet rich in whole foods supports healing and energy. Lean proteins, such as chicken, fish like salmon and mackerel, and legumes including lentils and chickpeas, are important for tissue repair and immune function. Complex carbohydrates like brown rice, quinoa, whole wheat bread, and sweet potatoes offer sustained energy. Incorporating healthy fats, particularly omega-3 fatty acids found in fatty fish, can also help reduce inflammation associated with shingles symptoms. Staying well-hydrated by drinking plenty of water, herbal teas, and consuming hydrating foods like watermelon, cucumber, and leafy greens is equally important to prevent dehydration.

Foods Rich in Immune-Supporting Nutrients

Specific vitamins and minerals play a significant role in supporting the immune system, which is especially relevant during a viral infection such as shingles. Vitamin C, an antioxidant, helps enhance immune function and can be found in citrus fruits like oranges, lemons, and grapefruits, as well as berries, bell peppers, and leafy greens, helping the body fight off the virus. Zinc is another mineral that supports a strong immune system and aids in wound healing; good sources include legumes, nuts, seeds, whole grains, and animal products. B vitamins, present in whole grains, eggs, leafy greens, fish, chicken, and dairy, contribute to energy production, nerve health, and the creation of antibodies, supporting immune response. Additionally, Vitamin D, found in fatty fish, eggs, and fortified foods, also plays a part in supporting immune health.

Understanding Lysine and Arginine

The balance between the amino acids lysine and arginine is considered a factor in managing herpes viruses, including the varicella-zoster virus that causes shingles. Some research suggests that a higher intake of lysine and a lower intake of arginine may be beneficial, as arginine can potentially support viral replication. This dietary approach is viewed as a supportive strategy rather than a primary treatment for shingles. Foods rich in lysine include dairy products like milk, yogurt, and cheese, various types of fish such as salmon and cod, chicken, eggs, and beef. Conversely, foods with higher arginine content that might be considered for moderation include:

Nuts (peanuts, almonds, walnuts)
Seeds (pumpkin, sesame, sunflower)
Chocolate and gelatin
Canned tuna and wheat germ
Brussels sprouts, grapes, blackberries, and soy products.

Foods to Limit or Avoid

When dealing with shingles, certain foods may hinder recovery or exacerbate symptoms, making it advisable to limit or avoid them. Highly processed foods, often high in unhealthy fats, additives, and preservatives, can increase inflammation in the body, including items like sodas, candies, packaged snacks, and fast food. Excessive sugar intake and refined carbohydrates, such as white bread, pasta, white rice, and sugary cereals, can impair immune function, promote inflammation, and lead to rapid blood sugar spikes, negatively affecting immune response. Additionally, spicy foods may intensify the pain and discomfort associated with shingles by stimulating nerve endings. Alcohol consumption can weaken the immune system, potentially interact with medications, and contribute to dehydration, making it important to limit or avoid during a shingles outbreak.
