Seasonal allergies, also known as hay fever or allergic rhinitis, are a common condition that affects millions of people worldwide. These allergies are triggered by pollen from trees, grass, and weeds, and they typically occur during certain seasons, such as spring, summer, and fall. The symptoms of seasonal allergies—such as sneezing, nasal congestion, itchy eyes, and a sore throat—can significantly impact quality of life. While medications like antihistamines and nasal sprays are often used to alleviate symptoms, dietary changes can also play a role in managing allergic reactions. Certain foods may help reduce inflammation and boost the immune system, while others may exacerbate symptoms. This article will explore which foods to eat and avoid when dealing with seasonal allergies.
The Role of Diet in Managing Seasonal Allergies
While there is no magic food that can completely cure seasonal allergies, some foods contain anti-inflammatory properties and nutrients that can help reduce the severity of allergic reactions. On the other hand, certain foods can worsen symptoms, either by triggering inflammation or by exacerbating histamine release in the body. Understanding how diet influences your allergies can help you make more informed decisions about what to eat and what to avoid.
Foods to Eat for Seasonal Allergies
If you’re looking to reduce allergy symptoms naturally, there are several types of foods that can help your body better manage seasonal allergies. These foods are typically rich in antioxidants, vitamins, and minerals that support the immune system and reduce inflammation.
1. Omega-3 Fatty Acids
Omega-3 fatty acids, found in fatty fish and certain plant-based sources, have well-documented anti-inflammatory properties. These healthy fats can help reduce the production of inflammatory chemicals that contribute to allergy symptoms. Fish like salmon, mackerel, and sardines are excellent sources of omega-3s. If you follow a plant-based diet, you can get omega-3s from flaxseeds, chia seeds, and walnuts.

Foods to try: Salmon, mackerel, sardines, flaxseeds, chia seeds, walnuts.
2. Local Honey
Local honey is often recommended for individuals with seasonal allergies, as it may help the body build tolerance to local allergens over time. The idea is that local honey contains trace amounts of pollen from the area, which, when consumed regularly, might reduce allergic reactions to that pollen. While scientific evidence on this is limited, some people find it helpful to include a small amount of local honey in their diet.
-
Foods to try: A spoonful of local honey added to tea, yogurt, or smoothies.
3. Antioxidant-Rich Fruits and Vegetables
Fruits and vegetables that are rich in antioxidants, such as vitamin C, can help combat inflammation and boost your immune system. Vitamin C is known for its ability to reduce histamine levels in the body, which can relieve allergy symptoms. Citrus fruits like oranges, lemons, and grapefruits, as well as berries, bell peppers, and leafy greens, are all excellent sources of vitamin C.
-
Foods to try: Oranges, strawberries, bell peppers, broccoli, kale, spinach, tomatoes.
4. Ginger and Turmeric
Both ginger and turmeric are known for their anti-inflammatory and immune-boosting properties. These spices contain compounds that can help reduce inflammation and may help alleviate symptoms of allergic rhinitis. Ginger has natural antihistamine properties and can help soothe a sore throat or reduce nausea. Turmeric, thanks to its active compound curcumin, also has potent anti-inflammatory effects.
-
Foods to try: Ginger tea, turmeric lattes, turmeric supplements, ginger added to smoothies, soups, or stir-fries.
5. Probiotic-Rich Foods
Probiotics, the beneficial bacteria found in fermented foods, can support gut health, which plays a crucial role in immune function. A healthy gut microbiome can help regulate immune responses and may reduce the severity of allergic reactions. Foods like yogurt, kefir, kimchi, sauerkraut, and kombucha are rich in probiotics and can support the body’s natural defenses against allergens.

Foods to try: Yogurt, kefir, sauerkraut, kimchi, kombucha.
6. Herbal Teas
Certain herbal teas can help relieve allergy symptoms. Peppermint tea, for example, can help open up nasal passages and relieve congestion, while chamomile tea is known for its calming and anti-inflammatory properties. Nettle tea is another option, as it has natural antihistamine effects that can help reduce allergy symptoms.
-
Foods to try: Peppermint tea, chamomile tea, nettle tea.
Foods to Avoid with Seasonal Allergies
Just as certain foods can help ease allergy symptoms, others can worsen them. Some foods contain high levels of histamine or trigger inflammation, making them problematic for individuals with seasonal allergies. Additionally, some foods may cross-react with pollen, meaning they contain proteins similar to those found in certain allergens, which can worsen symptoms. These foods are known as “oral allergy syndrome” (OAS) foods.
1. Histamine-Rich Foods
Histamine is a compound released during allergic reactions that causes symptoms like itching, swelling, and congestion. Certain foods naturally contain high levels of histamine, which can exacerbate allergic reactions. These foods include fermented foods, aged cheeses, cured meats, and alcoholic beverages. People with seasonal allergies may be more sensitive to histamine, leading to heightened allergy symptoms.
-
Foods to avoid: Aged cheeses (cheddar, parmesan), cured meats (salami, pepperoni), fermented foods (sauerkraut, soy sauce), alcohol (especially wine and beer).
2. Foods That Cross-React with Pollen
Some foods have proteins that are similar to those found in certain pollens, leading to a phenomenon known as oral allergy syndrome (OAS). Individuals with pollen allergies may experience symptoms like itching or swelling in the mouth and throat after consuming these foods. Common foods that cross-react with pollen include certain fruits, vegetables, and nuts.
-
Birch pollen cross-reacts with: Apples, cherries, carrots, celery, hazelnuts, almonds, and peaches.
-
Ragweed pollen cross-reacts with: Bananas, melons (cantaloupe, watermelon), cucumbers, zucchini, and sunflower seeds.
-
Grass pollen cross-reacts with: Tomatoes, potatoes, and oranges.
3. Dairy Products
Dairy products can contribute to mucus production and may worsen congestion in some individuals. While not everyone with seasonal allergies will be affected by dairy, some people find that dairy exacerbates their symptoms, particularly when it comes to nasal congestion and a post-nasal drip. If you notice that dairy increases your symptoms, it may be worth reducing or eliminating it from your diet during allergy season.
-
Foods to avoid: Milk, cheese, yogurt, ice cream.
4. Processed Foods and Sugars
Processed foods, particularly those high in refined sugars and unhealthy fats, can contribute to systemic inflammation and exacerbate allergy symptoms. These foods can also compromise immune function, making it harder for the body to fight off allergens. Reducing your intake of sugary snacks, processed meats, and fast food can help minimize inflammation and support overall health.
-
Foods to avoid: Sugary snacks, sodas, fast food, processed meats (hot dogs, bacon).
Conclusion
Managing seasonal allergies involves a multifaceted approach, and diet can play an important role in reducing symptoms. By incorporating anti-inflammatory foods, antioxidants, probiotics, and certain spices into your diet, you can help support your immune system and reduce the severity of allergy symptoms. On the other hand, it’s important to avoid foods that can worsen inflammation, trigger histamine release, or cause cross-reactivity with pollen.
While dietary changes alone may not eliminate allergy symptoms, they can complement other treatments like antihistamines, nasal sprays, and allergen avoidance strategies. If you have severe seasonal allergies, it’s always a good idea to consult with a healthcare provider or nutritionist for personalized recommendations and guidance.
