From quercetin-rich fruits to anti-inflammatory spices, your diet can be your allergy ally.

As pollen counts rise and flowers bloom, many individuals find themselves battling spring allergies — with sneezing, runny noses, and itchy eyes becoming an annual nuisance. While medications can provide relief, a growing body of research suggests that your diet may also play a pivotal role in easing allergy symptoms. By incorporating nutrient-rich, anti-inflammatory foods into your meals, you can bolster your immune system and help your body manage histamine responses more effectively. Here are 15 foods that could help fight off those seasonal sniffles and support your overall health.

1. Apples

Apples are rich in quercetin, a plant-based antioxidant known for its natural antihistamine and anti-inflammatory properties. Quercetin may help inhibit the release of histamines responsible for typical allergy symptoms such as sneezing and watery eyes. For maximum benefits, enjoy apples with their skin on, as this is where quercetin is most concentrated.

Contains vitamin C for immune support.
Best consumed fresh and raw rather than cooked.
Other quercetin-rich foods: berries, grapes, cabbage, cauliflower, onions.

2. Onions

Onions are another exceptional source of quercetin and provide anti-allergic and antioxidant effects. Red onions, in particular, have the highest quercetin content and may help reduce inflammation in airways and decrease histamine reaction severity. In addition to their antihistamine effect, onions also contain sulfur compounds that support detoxification and immune health.

Enhances flavor in salads, sandwiches, or cooked dishes.
Can be enjoyed raw or lightly sautéed for optimal benefits.

3. Berries

Loaded with vitamin C and antioxidants, berries such as strawberries, blueberries, and raspberries can help quell allergic inflammation and strengthen the immune system. Vitamin C intake is associated with fewer allergic symptoms, likely because of its role in stabilizing mast cells that release histamine.

High water content helps keep you hydrated, reducing histamine levels.
Enjoy fresh berries as snacks, in smoothie bowls, or tossed into salads.
Strawberries, in particular, are a surprising source of vitamin C.

4. Citrus Fruits

Oranges, grapefruits, lemons, and limes — all citrus fruits — are classic immune boosters packed with vitamin C. Regular consumption may help lower the severity and frequency of allergy symptoms by decreasing inflammation and strengthening immune function.

Eat whole citrus fruits or drink freshly squeezed juice (in moderation).
Combine with leafy greens for a springtime salad to boost absorption.

5. Pineapple

Pineapple stands out thanks to bromelain, a digestive enzyme that helps ease nasal swelling and relieve sinus congestion. Bromelain’s anti-inflammatory effects have been shown to benefit those struggling with airway irritation, making pineapple a delicious way to calm spring symptoms.

Pair fresh pineapple with spicy foods to offset congestion naturally.
Also try adding it to smoothies or fruit salsas.

6. Kiwi

With its fuzzy skin and vibrant green flesh, kiwi is a vitamin C powerhouse. Just one large kiwi supplies more than 100% of your daily vitamin C needs. It’s also effective at curbing histamine levels and reducing the likelihood of nasal stuffiness or wheezing.

Good source of fiber and antioxidants.
Eat as-is or add to yogurt and cereal bowls.

7. Broccoli

Broccoli, a cruciferous vegetable, is packed with vitamin C and anti-inflammatory compounds. It also contains sulforaphane, which has been researched for its capacity to clear out blocked sinuses and support immune health during allergy season.

Other cruciferous vegetables: Brussels sprouts, cauliflower, cabbage.
Lightly steam or roast for best nutrient preservation.

8. Tomatoes

High in the antioxidant lycopene and vitamin C, tomatoes have significant anti-inflammatory benefits. Research indicates that regular tomato consumption may help lower inflammation, thereby reducing the likelihood of developing allergy-related symptoms.

Eat raw in salads or sandwiches, or blend into fresh salsas.
Cooking tomatoes increases lycopene availability, but vitamin C is best preserved raw.

9. Red Peppers

Red peppers are one of the richest sources of vitamin C, exceeding even oranges in their content per serving. Their vibrant hue is a sign of their antioxidant strength, which can help minimize allergic inflammation and support respiratory health.

Add sliced raw peppers to salads or dip them in hummus.
Rich in beta-carotene, which further boosts immune defense.

10. Fatty Fish (Salmon, Tuna, Mackerel)

Fatty fish such as salmon, tuna, and mackerel are abundant in omega-3 fatty acids, which help to reduce inflammation and may lessen the severity of airborne allergies. Studies have found that those who consume higher amounts of these fish experience fewer and milder allergic reactions compared to those who do not.

Omega-3s also found in walnuts, flaxseeds, and chia seeds.
Aim for two servings of fatty fish per week for benefits.

11. Walnuts

Walnuts contain alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid that helps curb inflammation and allergic responses. Additionally, walnuts provide selenium, an antioxidant mineral that further reduces allergic stress on the body.

Snack on a handful daily or sprinkle onto oatmeal and salads.
Other good nut choices: almonds (magnesium-rich), cashews.

12. Flaxseed and Chia Seeds

Both flaxseed and chia seeds are rich in ALA omega-3s. These seeds not only dampen systemic inflammation but also support healthy digestion, which is linked to immune resilience and allergy control.

Sprinkle ground flaxseed onto cereals, yogurts, or blend into smoothies.
Chia seeds can be added to overnight oats, puddings, or baked goods.

13. Yogurt and Fermented Foods

Probiotic-rich foods like yogurt, kefir, sauerkraut, and kimchi supply “good” bacteria that benefit gut health and, in turn, support immune regulation. A well-functioning immune system is better equipped to process environmental allergens with minimal irritation. Choose yogurts labeled “live and active cultures” for optimal benefits.

Enjoy as a snack or breakfast base alongside fruit and nuts.
Fermented varieties like kimchi and sauerkraut add a tangy kick to meals.

14. Turmeric

Turmeric, a vivid yellow spice, gets its medicinal power from curcumin, an active compound renowned for its anti-inflammatory and antioxidant effects. Research suggests that curcumin supplementation can ease symptoms of allergic rhinitis (hay fever), reduce sneezing, and improve nasal airflow.

Stir into curries, golden milk, or blend with smoothies.
For better absorption, pair with black pepper and a healthy fat.

15. Local Honey

While the research is mixed, some people report relief from seasonal allergies by regularly consuming local honey. The theory is that small doses of local pollen in the honey help acclimatize your immune system, thereby lessening its reaction to airborne pollens. Though not a proven cure, it’s a safe and tasty option to try.

Use in teas, drizzle on fruit, or swirl into yogurt.
Start with a small daily dose before allergy season begins for potential effects.
