In today’s fast-paced world, maintaining resilient immunity is more important (and challenging) than ever. The key to a robust immune system lies not only in regular exercise, a regulated nervous system, a reduction in toxic exposures through our air, water, skincare, and cleaning products, and proper sleep, but also in the foods we consume. Holistic nutrition teaches us that nourishing our bodies with nutrient-dense, whole foods is a foundational component of optimal well-being, which includes immune health. In this blog post, we’ll explore 10 superfoods that can promote immune resiliency and help you feel your best.
Citrus
Citrus fruits, such as oranges, grapefruits, lemons, and limes, are well-known for their high vitamin C content. Vitamin C is a powerful antioxidant that supports immune function by stimulating the production of white blood cells, which are essential in fighting off infections. Vitamin C is water-soluble though, which means that we need obtain it regularly via the foods we eat. Incorporating a variety of citrus fruits into your diet provides a steady supply of this immune-supportive nutrient.
Berries
Strawberries, blueberries, raspberries, and blackberries are rich in antioxidants and vitamins that help protect cells from damage. They’re particularly high in vitamin C and flavonoids, which have been linked to improved immune response. Add a handful of fresh or frozen colorful berries to your smoothies, yogurt, or oatmeal for a flavorful and nutritious boost!
Garlic
Garlic has been valued for its medicinal properties for centuries. It contains a compound called allicin, which has antimicrobial and immune-enhancing effects. For maximum benefit, crush your garlic well, and allow it to sit for 10-15 minutes before adding it to your dish. It can also help to add it in the last few minutes of cooking. Incorporate fresh garlic into your meals to not only add flavor but also to support your immune system’s ability to fight off infections.
Ginger
Ginger is known for its anti-inflammatory and antioxidant properties. It contains gingerol, a bioactive compound that may help lower risk of infection. It can also be an excellent support for nausea and heartburn. Enjoy ginger in teas, soups, or as a flavor enhancer in various dishes to reap its immune-boosting benefits.
Turmeric
Turmeric contains curcumin, a compound with potent anti-inflammatory and antioxidant properties. Curcumin’s immune-boosting effects may help regulate the immune response and promote overall immune system health. It is best absorbed when consumed with a small amount of a quality fat (such as ghee or coconut oil), and some crushed black pepper. Add turmeric to curries, soups, or golden milk for a flavorful and nourishing twist.
Leafy Greens
Leafy greens like spinach, kale, and Swiss chard are packed with vitamins A, C, and K, as well as a multitude of antioxidants and minerals that can contribute to immune function and overall health. We would also add sprouts to this category, which are even more nutrient-dense, and contain a variety of enzymes that can help to boost absorption of those nutrients. Whether enjoyed in salads, smoothies, or sautéed dishes, leafy greens and sprouts are a versatile way to boost your immune resilience.
Probiotics and Prebiotics
Probiotics are a variety of microbes that are often found in yogurt and other fermented foods, such as sauerkraut, kimchi, and coconut kefir. Prebiotics are the indigestible plant fibers we consume when we eat fruits, vegetables and other fibrous foods. We may not digest prebiotics, but our gut microbiome does. A significant portion of our immune system resides in our digestive tract, so maintaining a healthy balance of gut bacteria through our consumption of both probiotics and prebiotics can be helpful in mounting a healthy immune response.
Nuts and Seeds
Nuts and seeds, such as almonds, walnuts, chia seeds, and sunflower seeds, provide brain-boosting fats, protein, and essential nutrients like vitamin E and zinc. Vitamin E is an antioxidant that helps protect cells from damage, while zinc is known for its role in immune cell function. Consume a small amount of nuts and seeds each week to promote satiety and support your immune system!
Green Tea
Green tea is rich in catechins, antioxidants that have been shown to enhance immune function. The polyphenols in green tea may also have anti-inflammatory properties. When you drink green tea, you can even add a squeeze of lemon juice for some additional vitamin C, and to enhance the absorption of immune-protective catechins!
Mushrooms
Certain mushrooms, such as shiitake, reishi, chaga, lion’s mane, turkey tail, and maitake, have been used for centuries in traditional medicine for their immune-modulating properties. They contain compounds that may enhance the activity of immune cells and improve overall immune response. Today, they can be found processed in a variety of different ways for ease of consumption, so you don’t need to like the taste of mushrooms to reap their medicinal benefits. Check your local health foods store for medicinal mushroom powders that can be added to smoothies, tinctures that can be taken under the tongue, and teas that can be steeped and sipped any time!
Final Thoughts
While there is certainly no single magical food option that can guarantee immunity, nor should food be the only area of focus when we are looking to support our immune system, incorporating these medicinal superfoods into your diet can certainly contribute to a strong and resilient immune system overall. Holistic nutrition teaches us that a balanced and varied diet, rich in a variety of nutrient-dense, colorful foods, is a cornerstone of health.
Remember: A holistic approach to nutrition embraces the connection between food, lifestyle, and well-being, so pair these superfoods with regular exercise, adequate sleep, a reduction in the consumption of processed foods, and nervous system support for the most well-rounded approach to immune resilience.
