Seasonal allergies can be frustrating, but dietary changes can help reduce symptoms. A healthy diet can ease inflammation and sinus congestion, reducing the severity and frequency of allergy attacks. Eating clean, fresh foods such as fruits, vegetables, beans, whole grains, fish, and olive oil can help with many respiratory allergies, including asthma. Reducing salt intake and consuming foods rich in vitamins and minerals can also help strengthen the immune system and alleviate allergy symptoms.

What You'll Learn
Consume more vitamin C, zinc, and magnesium
Consuming more vitamin C, zinc, and magnesium can be beneficial in reducing allergy symptoms, but it is worth noting that in rare cases, people can also be allergic to magnesium.
Vitamin C, also known as ascorbic acid, is a natural antihistamine and antioxidant. It reduces the amount of histamine produced by the body, which is responsible for allergy symptoms such as inflammation and swelling. Research has shown that taking 2 grams of vitamin C can reduce histamine levels by about 38%. For those with allergies, a higher dose of 7.5 grams administered intravenously resulted in a 50% reduction in histamine levels. The recommended dose for allergic rhinitis is 2,000 mg per day, and it is considered safe due to its low risk of toxicity and minimal side effects.
Zinc is an essential mineral found in many foods, including meat, poultry, shellfish, dairy products, wholegrain foods, beans, nuts, and seeds. Studies have linked low zinc levels to allergies, and people with asthma and allergic rhinitis tend to have lower zinc levels. Zinc supplementation has been shown to alleviate respiratory allergy symptoms and shorten the duration of common cold symptoms.
Magnesium is a mineral vital for nerve function, muscle contraction, and a healthy immune system. It also contributes to bone development and energy production. While magnesium is typically beneficial, it is important to note that some individuals may have a magnesium allergy, which can manifest as skin reactions, respiratory difficulties, or gastrointestinal issues. If you suspect a magnesium allergy, consult a healthcare professional for diagnosis and treatment.
In summary, increasing your intake of vitamin C, zinc, and magnesium through diet or supplements may help reduce allergy symptoms. However, it is always advisable to consult a healthcare professional before starting any new supplements or making significant dietary changes.

Eat more fruits and vegetables
Eating more fruits and vegetables is a great way to reduce allergies through diet. Firstly, fruits and vegetables are rich in vitamins and minerals, which are essential for supporting overall health and wellness. Specifically, oranges, lemons, limes, grapefruit, berries, kiwis, and red peppers are high in vitamin C, which boosts the immune system and reduces inflammation associated with allergic reactions. In addition, fruits and vegetables are a good source of dietary fiber, which can help to reduce allergic inflammation.
Secondly, some fruits and vegetables contain natural anti-inflammatory compounds that can help to alleviate allergy symptoms. For example, tomatoes are rich in lycopene, an antioxidant that can lower the risk of developing inflammatory diseases. Similarly, onions, garlic, and apples contain quercetin, a natural antihistamine that can help to reduce allergic reactions.
Thirdly, a diet rich in fruits and vegetables can help to reduce overall inflammation in the body, which is often a contributing factor to allergy symptoms. Processed and fast foods, on the other hand, are high in omega-6 fatty acids and refined carbohydrates, which can increase inflammation and make allergy symptoms worse. By increasing your intake of anti-inflammatory foods, such as fruits and vegetables, you can help to reduce overall inflammation and improve your allergy symptoms.
Finally, a healthy diet that includes a variety of fruits and vegetables can help to improve gut health and support a diverse microbiome. This is important because the gut-immune connection is well-established, and a healthy gut can help to reduce the severity of allergic reactions. In addition, a diverse microbiome can help to regulate the body's immune response, preventing an overactive response to allergens.
However, it is important to note that some people may have allergies or sensitivities to specific fruits or vegetables. Oral Allergy Syndrome (OAS), also known as Pollen-Food Syndrome (PFS), is a common condition where people experience allergic reactions to certain raw fruits or vegetables due to cross-reactivity between pollen allergens and proteins in the food. Cooking these fruits or vegetables can often mitigate the allergic response, as the proteins that cause the reaction break down when heated. If you suspect you have OAS or any other type of food allergy, it is important to consult a healthcare professional for proper diagnosis and treatment.

Reduce salt and refined carbs
Reducing salt and refined carb intake can be beneficial for managing allergies and overall health. Firstly, decreasing salt consumption can positively impact lung function, which is beneficial for those with respiratory allergies. Much of the salt in people's diets comes from processed foods, so it is advisable to limit these and opt for fresh herbs and spices to season dishes instead. This can improve the flavour of food while reducing salt intake.
In addition to reducing salt, limiting refined carbohydrates can also help manage allergies. Refined carbs, such as white bread and pastries, can cause inflammation, which is a common trigger of allergy symptoms. Wholegrain or whole wheat options are healthier alternatives as they are digested more slowly, keeping you feeling full for longer, and they can also provide a good source of fibre, vitamins, and minerals.
To reduce refined carb intake, it is recommended to opt for whole grains such as brown rice, oats, barley, rye, and quinoa. These can be incorporated into meals in various ways, including porridge, whole wheat bread, and pasta. When choosing cereals, it is important to read the labels and compare the wholegrain content, as many options are refined and high in added salt and sugar.
By making conscious choices to reduce salt and refined carb intake, individuals can not only improve their overall health but also potentially reduce the severity of allergy symptoms. These dietary changes may be especially beneficial for those with respiratory allergies or inflammation-related allergies. It is worth noting that everyone's experience with allergies is unique, and it is always advisable to consult a healthcare professional for personalised advice.

Add turmeric, ginger, and garlic to your diet
Allergies occur when the body's immune system overreacts to harmless substances, treating them as potential threats. This results in inflammation, which causes symptoms such as swelling and irritation in the nasal passages, eyes, and throat.
To combat this, it is recommended to add turmeric, ginger, and garlic to your diet. Turmeric is a spice grown in various Asian countries and used in a lot of Indian cuisine. Its active component, curcumin, contains many anti-inflammatory properties that may help with a multitude of health problems. In a study on the effectiveness of curcumin at treating allergy symptoms, curcumin was found to improve nasal airflow, reduce sneezing and stuffiness, and boost immunity in patients. Turmeric can be added to your diet in the form of smoothies, curry, or golden milk drinks. It can also be taken in pill or tincture form, or used in teas. To increase the bioavailability of curcumin, it is recommended to pair turmeric with black pepper.
Ginger is another spice that can help with allergies. It is a natural remedy for nausea and joint pain and has been used as such for thousands of years. Its anti-inflammatory properties can help soothe irritated nasal passages and reduce congestion. A 2016 animal study showed that ginger suppressed the production of certain cytokines that cause mast cell activation, thereby alleviating allergic rhinitis symptoms.
Garlic is a potent natural antihistamine that can help reduce the production of histamine, a chemical that the body produces during an allergic reaction. By incorporating garlic into your diet, you can help manage common allergy symptoms like sneezing and itching.
In addition to these spices, it is also beneficial to consume foods rich in vitamin C, such as citrus fruits and tomatoes, as they have been shown to act as natural antihistamines and provide allergy symptom relief.

Eat fatty fish like tuna, salmon, and walnuts
Eating fatty fish like tuna, salmon, and mackerel is a great way to get omega-3 fatty acids, which are known to help reduce allergy symptoms and support your immune system. Omega-3 fatty acids are essential nutrients that can help manage your allergies and keep them from flaring up.
Salmon, tuna, and cod are considered the most common fish allergens, and an allergy to one type of fish may mean you are also allergic to other varieties. If you are allergic to a specific type of fish, your allergist can help you determine whether other varieties are safe to eat. An oral food challenge can be performed to test for allergies, and this is done under medical supervision. If you are allergic to fish, doctors will typically advise you to avoid all types of fish.
If you are not allergic, however, fatty fish like salmon and tuna are excellent sources of omega-3s and can easily be incorporated into your diet. You can try grilled salmon with a side of vegetables, or a tuna salad with leafy greens and olive oil. Just be sure to prepare and cook your fish safely, avoiding any cross-contamination with other types of fish that may trigger your allergies.
In addition to fatty fish, walnuts are another great source of omega-3 fatty acids. However, walnut allergies are quite common and often severe, so proceed with caution. If you are introducing walnuts to a child's diet, it is recommended to do so gradually and under supervision to reduce the risk of allergic symptoms and determine the severity of reactions.
