AIP Foods For Immune Health

With the onset on winter, cold and flu season becomes an inevitable reality. Poor sleep, high stress levels, and overindulging, even in healthy foods weaken your ability to fend off winter illnesses. While there is no guaranteed way to avoid getting sick, you can take steps to strengthen your immune system and reduce your risk of falling victim to seasonal bugs.

Although no single food or diet can cure or prevent disease, a lack of essential vitamins, minerals, and micronutrients, can impair your ability to fight off illness and infection. The nutrient-dense, anti-inflammatory foods enjoyed on the Autoimmune Protocol (AIP) diet, known for supporting overall health and vitality, can also bolster your immune defenses against harmful pathogens.

The best way to support your immune system is to regularly consume seasonal, local, humanely raised, and pesticide-free real food. These nutrient-dense options provide essential vitamins, minerals, phytonutrients, antioxidants, and other compounds critical for immune health. Adding bone broth to your diet is particularly beneficial as it supports gut health, reduces inflammation, and detoxifies the body, while also helping combat respiratory infections.

To further enhance your immune resilience, consider the following AIP-friendly foods and practices:

Load Up on Vitamin C

Vitamin C is a powerful immune booster that helps your body fend off infections and may reduce the severity and duration of colds. Excellent AIP-compliant sources of vitamin C include citrus fruits like lemons, oranges, and grapefruits, as well as fruits like kiwi. Incorporating cruciferous vegetables like broccoli and cauliflower is also highly beneficial, as they are rich in both vitamin C and other immune-supporting compounds.

Support Gut Health with Probiotics

A healthy gut is foundational to a strong immune system. Probiotic-rich, fermented foods such as sauerkraut, kimchi, and naturally fermented vegetables can help maintain a balanced gut microbiome. Coconut yogurt, made without added sugars, is another AIP-friendly option for introducing probiotics into your diet.

Embrace Zinc-Rich Foods

Zinc is a critical mineral for immune system function, reducing the severity and duration of colds caused by viruses. AIP-friendly zinc sources include shellfish, particularly oysters, which are among the richest sources of zinc. Grass-fed meats, organ meats like liver, and poultry also provide significant amounts of this essential nutrient.

Alliums: Nature’s Antibiotic

Garlic, onions, leeks, and shallots are prized for their antiviral, antibacterial, and antifungal properties. They also provide gut-supportive prebiotic fibers. For maximum benefits, crush or chop alliums and allow them to sit for a few minutes before consumption. Cooking them gently preserves their beneficial compounds while enhancing their flavor.

Boost with Turmeric

Turmeric, containing the active compound curcumin, is a potent anti-inflammatory and antioxidant. Adding turmeric to your meals or sipping on a warm cup of turmeric tea can help reduce inflammation and support immune function. Pair turmeric with black pepper to enhance the absorption of curcumin, or include it in dishes like soups and stews for added warmth and flavor.

Create a Colorful Plate

Eating a variety of vibrantly colored fruits and vegetables ensures a diverse intake of vitamins, minerals, and antioxidants. Incorporate foods like blueberries and pomegranates and leafy greens such as spinach, kale, and Swiss chard into your meals. These nutrient-rich options are particularly high in vitamin C and vitamin A, which are vital for immune health. Purple vegetables like cabbage and beets, along with orange options such as carrots and winter squash, also provide valuable antioxidants and phytonutrients.

Stay Hydrated

Proper hydration is essential for optimal immune function. Water helps flush out toxins and transports nutrients throughout the body. Herbal teas like chamomile, ginger, and echinacea provide additional immune-boosting properties while soothing symptoms like sore throats and congestion. Coconut water can also be a hydrating, electrolyte-rich option for added variety.

Sip on Bone Broth

Bone broth is a nutrient powerhouse for the immune system. Rich in amino acids like proline, bone broth supports the production of antibodies and stimulates immune responses. It also reduces inflammation, repairs tissues, and protects the brain and nerves. If you’re short on time, consider ready-made options like Paleo on the Go’s long-simmered bone broth for convenience. Add fresh herbs like thyme or parsley to enhance its flavor and nutritional profile.

Increase Vitamin D Intake

Vitamin D is crucial for immune regulation. While food sources like fatty fish and pastured eggs can provide some vitamin D, sunlight exposure remains the best way to boost levels naturally. Consider supplements if needed, especially during the winter months. Incorporating mushrooms, such as shiitake or maitake, which have been exposed to sunlight, can also provide a plant-based source of vitamin D.

Limit Sugar Intake

Excessive sugar, even natural, AIP friendly sweeteners like dates and maple syrup can suppress immune function, making you more vulnerable to infections. Focus instead on whole, unprocessed foods and incorporate naturally sweet foods like roasted root vegetables or seasonal fruits to satisfy cravings.

Prioritize Rest and Sleep

No dietary strategy can replace the restorative power of quality sleep. Aim for 7-9 hours per night to allow your body to repair and recharge, ensuring your immune system functions optimally. Consider incorporating calming evening rituals like herbal teas, meditation, or gentle stretching to improve sleep quality.

In Summary

By incorporating these AIP-compliant foods and lifestyle practices into your daily routine, you can build a robust immune system capable of facing the challenges of cold and flu season. Nourishing your body with real, nutrient-dense foods is your best defense against illness, empowering you to stay vibrant and healthy year-round.
