Hay fever, also known as allergic rhinitis, affects millions of people worldwide and can lead to annoying symptoms such as a runny nose, itchy eyes, and sneezing. Although medications are often used to treat these symptoms, recent studies suggest that certain foods may also help reduce hay fever symptoms.

In this article, we discuss 5 foods that may offer relief and the biological mechanisms underlying their effects.

1. Local honey

Honey has been used for centuries as a natural remedy for allergies, including hay fever. It is believed that honey contains local pollen, which exposes the body to small amounts of allergens and enhances immunity against these allergens.

A study conducted by Pasalar et al. (2011) showed that consuming local honey over a period of time significantly reduced the symptoms of hay fever in patients suffering from this condition.

2. Quercetin-rich foods

Quercetin is a bioactive substance that naturally occurs in certain foods such as apples, onions, berries, and capers. It is known for its anti-inflammatory and antihistamine properties, which can help reduce the symptoms of hay fever.

A study published in the journal Nutrients (2016) showed that quercetin supplementation reduced the symptoms of allergic rhinitis and decreased inflammation in the airways.

3. Omega-3 Fatty Acids

Omega-3 fatty acids, primarily found in fatty fish, flaxseeds, and walnuts, have anti-inflammatory properties that may be beneficial for people with hay fever. They can help reduce inflammation in the airways and balance the immune system.

A study published in The Journal of Allergy and Clinical Immunology (2013) suggested that a diet high in omega-3 fatty acids could help reduce the severity of hay fever symptoms.

4. Probiotic-rich foods

Probiotics, or beneficial bacteria that naturally occur in certain foods like yogurt, kefir, and fermented vegetables, can have a beneficial effect on the immune system and reduce inflammatory responses.

A systematic review published in the International Forum of Allergy & Rhinology (2015) concluded that probiotic supplementation could help reduce the symptoms of allergic rhinitis.

5. Ginger

Ginger, a commonly used herb with a strong, distinctive flavor, is known for its anti-inflammatory properties. It contains bioactive components such as gingerol and shogaol, which can inhibit inflammatory responses in the body.

A study published in the journal Phytotherapy Research (2016) showed that ginger extract was significantly effective in reducing symptoms of allergic rhinitis, including sneezing and a stuffy nose.

Conclusion

Although more research is needed to confirm the precise effects of these foods on hay fever symptoms, these studies show promising results. Including these foods in a balanced diet may be a natural complement to conventional treatments for hay fever.
