Allergies are more common than ever with nearly 6% of adults and children in the US have some form of food allergy, and that number continues to rise. Whether it’s a peanut reaction, seasonal sneezing, or unexplained flare-ups after certain meals, allergies are increasingly linked to the immune system’s overreaction. And here’s where it gets interesting, your diet might be the missing link—not just in managing symptoms, but in preventing them in the first place.The mainstream response to allergies often begins and ends with antihistamines but according to certified dietitian Lavleen Kaur, healing starts from within, “Allergies—whether triggered by food, weather changes, or environmental factors—are signs of an overactive immune system. True healing begins from within. Building natural immunity through nutrition is a long-term, sustainable approach that not only helps prevent allergic flare-ups but also strengthens overall health.”Expert dietician reveals how your food and lifestyle choices can shape your immune response—and how a few shifts could help you reduce allergic reactivity naturally.Immune System Starts in the GutRoughly 70% of your immune system lives in your gut. This isn’t just an interesting stat—it’s the reason nutrition plays such a central role in how your body handles allergens. A gut that’s inflamed, leaky, or dominated by bad bacteria is more likely to misfire, reacting to harmless proteins in food or the environment.Kaur emphasizes the importance of nurturing this digestive-immune connection: “When the digestive system is strong, the immune system becomes less reactive. That’s why I often say, ‘Immunity begins at home’—not through expensive supplements, but through simple, consistent habits rooted in traditional wisdom.”Start Your Day with Immunity-Boosting RitualsForget the hype around complicated health tonics. According to Kaur, the day should start with an old-school combination that’s surprisingly effective: one fig, two dates, and 3–4 black raisins, soaked overnight. “This combination is rich in iron, helps build stamina, and keeps oxygen flowing efficiently in the body,” she says.Follow that up with probiotic-rich foods like curd, fermented kanji, or buttermilk. These naturally populate your gut with beneficial bacteria, improve digestion, and enhance immune balance.Hydration is another non-negotiable. “Pale-yellow urine is a sign you’re well-hydrated,” says Kaur. She recommends rotating plain water with coconut water, herbal teas, and turmeric-ginger infusions—especially during allergy season, when respiratory health is easily compromised.Eat with the Seasons, Not the Supermarket ShelfThere’s a reason your grandmother swore by seasonal eating. Fresh, in-season produce isn’t just better for the planet—it’s better for your immune system. Kaur urges people to “fill your plate with a rainbow of seasonal fruits and vegetables, especially those high in vitamin C like amla, guava, oranges, and bell peppers.”Another group of nutrients to focus on? Quercetin and omega-3 fatty acids. Quercetin—a powerful antioxidant found in apples and onions—helps modulate the body’s histamine response, meaning fewer flare-ups. Omega-3s from flaxseeds, walnuts, and chia seeds work at the cellular level to reduce inflammation and balance immunity.Gut Rituals that Support Allergy ReliefBeyond meals, Kaur recommends ancient digestive practices that keep the gut calm and efficient. After meals, chew a small amount of fennel seeds, cardamom, or clove with jaggery. This supports digestion and prevents the post-meal sluggishness that can signal immune stress.At bedtime, her go-to ritual is a glass of warm turmeric milk. Turmeric is anti-inflammatory, and combining it with milk (or a plant-based alternative) enhances absorption. This simple step not only improves sleep but supports overnight cellular repair and immune regeneration.Identify Your Real TriggersWhat derails your immunity faster than pollen season? Ultra-processed foods. Refined sugar, deep-fried snacks, chemical additives, and preservative-laden packages are well-known immune suppressors. These foods also disrupt gut flora and increase inflammation, making your system more reactive.Some people may benefit from limiting gluten or dairy, especially if allergies persist despite clean eating but Kaur cautions that elimination should always be done under guidance. “Removing a food group without support can lead to deficiencies. The goal is to reduce inflammation—not create new problems.”Ancient Ayurvedic Ways To Relive AllergyModern medicine isn’t the only tool available for allergy relief. Kaur encourages integrating Ayurvedic practices like:Udvartan (herbal dry massage) for detoxifying the skinNasya therapy (medicated nasal drops) for clearing the sinuses and balancing the mindShirodhara (streaming warm oil over the forehead) to regulate nervous system sensitivityThese therapies support the body's natural detox processes and promote systemic balance—especially helpful for those with chronic skin, respiratory, or seasonal allergies.If you’re looking for a magic pill or a shortcut, nutrition-led immunity might disappoint you. But if you’re after something sustainable, preventive, and empowering, this approach could change your life.Building a stronger immune system isn’t about perfection. It’s about consistency. Kaur puts it simply: “When the body is nurtured consistently through nutrition and lifestyle, it becomes less reactive, more resilient, and deeply aligned with nature.”In a world overflowing with medications, allergy shots, and crisis responses, the anti-allergy diet offers a grounded, proactive path—one meal, one habit, one day at a time.Allergies don’t have to control your life. By rethinking your plate, daily rituals, and how you support your gut, you can create an environment where your immune system works with you—not against you. Nutrition won’t replace your EpiPen, but it might help you reach for it less often and that’s worth chewing on.Lavleen Kaur is the Chief Dietitian & Founder, Santushti Holistic Healthcare & Diet Insight Nutrition Academy
