As the weather warms and trees and grasses begin to bloom, the challenges of seasonal allergies also rise. The condition is called allergic rhinitis or hay fever and affects 19.2 million U.S. adults and 5. (2) million children. (1) Many doctors lean heavily on prescription drugs to alleviate symptoms.

Yet it’s a good idea to also incorporate alternative nutritional options to reduce your dependence on medication. You are likely familiar with the common symptoms of sneezing, stuffy or runny nose, watery and itchy eyes. However, a sizable number of people with allergies also experience noticeable brain fog.

The inflammatory response triggered by an allergic reaction affects your brain. It can interfere with sleep and cause stuffiness in your middle ear. This inflammation can lead to feelings of dizziness or brain fog. (2) Data also suggest that allergies have a significant effect on cognitive function.

For example, it may impede learning in school-age children, (3) cause disturbed cognitive function in areas requiring sustained attention, short and long-term memory and information processing, (4) and may cause significant fatigue and mood changes. (5)

One study (6) found evidence to support a close relationship between an allergic response, inflammatory cytokines and sleep as potential mediators. There are several natural options available for people who experience seasonal allergic reactions. The following five foods are among those that help reduce the symptoms and inflammation associated with the condition. (7)

Properties in Ginger Reduce Seasonal Allergic Reactions

Ginger has a long history of medicinal use, including as a natural remedy for digestive and respiratory conditions. (8) High levels of anti-inflammatory phytochemicals may have contributed to the positive effects ginger had in an animal study (9) to suppress pro-inflammatory cytokines and mast cell activation, which reduces the symptoms of allergic rhinitis.

Another lab and human study (10) demonstrated Benifuuki green tea and ginger extract had a significant effect on suppressing cytokines and delayed type allergies. Eleven weeks after starting the study, those taking the Benifuuki tea had a reduced incidence of itchy eyes, runny nose and throat pain.

The results suggested a consecutive month of drinking the green tea with ginger extract could reduce the symptoms of seasonal rhinitis without affecting the normal immune response. Ginger holds several other benefits, including protecting against DNA damage after exposure to free radicals. In one landmark study, (11) ginger demonstrated the ability to reduce several inflammatory markers.

The most common use for ginger is in alleviating symptoms of nausea and vomiting. (12) One study (13) from the University of Miami showed ginger has the potential to replace non-steroidal anti-inflammatory drugs in patients with knee osteoarthritis. It was also as effective as pain medication in helping women with primary dysmenorrhea (menstrual cramps) (14) and was effective against exercise-induced muscle pain. (15)

Multiple Benefits From Superfood Bee Pollen

The honeybee produces valuable natural foods that some have called “superfoods.” (16) These include royal jelly, propolis and bee pollen. Bee pollen is the pollen honeybees bring back to the hive from plants in their geographical area.

Analysis has shown it contains eight of the nine essential amino acids that may be up to seven times higher than found in an equal weight of other high protein foods. Bee pollen is also high in bioflavonoids, vitamin B complex and vitamins A, C, D, E and K. It has traditionally been used for increasing energy and is even used by some Olympic athletes.

Analysis of the compound reveals it has anti-inflammatory, antimicrobial and antifungal properties in the body and radical scavenging potential. (17) Bee pollen mediates wound healing and has anticancer immune-stimulating properties. Further evaluation shows it can inhibit mast cell activation, (18) which triggers seasonal allergic reactions.

Bee pollen can also be used to help desensitize your body to your seasonal allergies. (19) For maximum effectiveness, begin taking bee pollen each day at least six weeks before you commonly begin showing allergy symptoms. Continue taking it throughout the season. The bee pollen helps to stimulate the production of antibodies, which in turn helps eliminate your allergic reaction.

Antioxidant Power of Vitamin C

Vitamin C is also known as ascorbic acid. When you think of foods high in vitamin C you might first think of citrus fruits like oranges and grapefruit. However, other good sources include bell peppers, strawberries, broccoli, Brussels sprouts and black currants. (20)

Vitamin C is a water-soluble vitamin that is an essential cofactor in several enzymatic reactions and has been linked with a lowered risk of high blood pressure, stroke and coronary heart disease. (21) Further evidence suggests it may be an adjunctive therapy to reduce heart injury after heart attack or a cardiac procedure.

You may be familiar with studies (22) that show regular use can modestly shorten how long you have the common cold. (23) But, did you know that vitamin C may also help reduce your symptoms of seasonal allergies?

One study (24) published in 2018 used intravenous vitamin C on patients with allergy related respiratory symptoms. Over 50% of the study participants only used vitamin C. The researchers found the observations suggested “intravenous high dose vitamin C reduces allergy-related symptoms.”(25)

Vitamin C is a natural antihistamine (26) and antioxidant. (27) Histamine is one of the inflammatory mediators that triggers symptoms (28) common in a seasonal allergic response. Some people find relief from their allergic symptoms when taking over-the-counter antihistamine drugs. (29)

Minimize Swelling From Allergic Rhinitis With Turmeric

Turmeric is from the ginger family, is a commonly used spice and is used in traditional medicine. (30) Historically, it was used in Ayurvedic medicine and traditional Chinese medicine (TCM). The main active ingredient in turmeric is curcumin, which gives the rhizome its yellow colour.

Curcumin has anti-inflammatory, antiseptic, antitumor and antioxidant properties. When used in an animal model, curcumin inhibited the release of histamine from mast cells and demonstrated a “marked inhibition of allergic response in animals treated with curcumin suggesting a major role for curcumin in reducing the allergic response.” (31)

A more recent human study (32) engaged 241 patients with symptoms of allergic rhinitis (AR) to test the efficacy of curcumin. The researchers measured nasal airflow resistance and found curcumin alleviated nasal congestion, sneezing and rhinorrhea. Past laboratory study suggested curcumin may have a significant effect on symptoms of seasonal allergies.

Researchers from this human study concluded, (33) “This pilot study provides the first evidence of the capability of curcumin of improving nasal airflow and modulating immune response in patients with AR.”

Wild-Caught Alaskan Salmon May Lower Allergic Sensitivity

Wild-caught Alaskan salmon is high in omega-3 fatty acids. There are three identified forms of omega-3 fats: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosa-hexaenoic acid (DHA). (34) ALA is found mostly in plants, while DHA and EPA are found in fatty fish and seafood.

Your body typically converts ALA to DHA at levels not nearly enough for brain and heart health. (35) Some studies have found the conversion rate is less than 0.5%. (36) In other words, to get enough EPA and DHA to have an anti-inflammatory effect on diseases such as asthma and allergies, (37) you need to eat foods rich in EPA and DHA.

Studies have also suggested a higher intake of omega-6 fatty acids is linked to an increased incidence of seasonal allergic responses. (38) Omega-6 fats can be found in processed seed or “vegetable” oils such as safflower, corn, soy and sesame oils. (39) In other words, most — if not all — processed foods.

There is also an association between taking omega-3 fats during pregnancy and a reduced incidence of seasonal allergies in infants and children, suggesting there is a protective association. (40) A cross sectional, population-based study (41) of 568 adults show that those with a higher omega-3 index had a decreased risk of allergic rhinitis.

Interestingly, they also found those with a higher dietary intake of ALA experienced some of the same reductions. A more recent study (42) analysed the association between the Mediterranean diet, high in omega-3 fatty acids, and chronic inflammatory diseases such as seasonal allergies.

They postulate that the solubility and uptake of certain phytochemicals may improve when consumed with omega-3 rich foods. This may explain the mechanism of action behind omega-3 fats’ and fat-soluble micronutrients’ role in the development of allergic inflammation.

More Helpful Strategies to Alleviate Seasonal Allergies

Seasonal allergies affect several body systems, so using a multifaceted approach increases the potential you’ll reduce symptoms and reactions. As with most health conditions that affect your immune system, it is crucial to start with a healthy gut.

Allergic reactions begin in the immune system when a relatively harmless protein triggers an overreaction, producing antibodies to attack the allergen. Your diet and gut health play crucial roles in optimizing your immune function.

Of course, a strategy that helps reduce symptoms is to reduce your exposure to the triggers. There are several ways to help, including limiting your time outdoors to when pollen counts are lowest. (43) This is usually in the late afternoon since on an average day pollen counts peak beginning midmorning. Limit outdoor time when the weather is warm, dry and windy as pollen counts may be higher.

Wear gloves while gardening and avoid touching your eyes. When you’re finished outdoors, take a shower and wash your clothes. Vacuum your home, including the furniture, regularly. Ideally, you’ll want to use a HEPA filter vacuum cleaner, leave your shoes at the door to avoid bringing pollen into your home and use a HEPA air filter to reduce your exposure to allergens. (44)

Nature has also provided several compounds that help offer relief from allergic rhinitis and seasonal allergies by supporting your immune system and blocking allergic symptoms, many of which are triggered from the histamine release. You’ll find a discussion of these, including quercetin, bromelain and methylsulfonylmethane (MSM) in “Spring Fever — How to Treat Allergies.”
