Diet and nutrition play a crucial role in managing allergies and reducing their symptoms. Seasonal allergies can be frustrating, but incorporating certain foods into your diet can help ease inflammation and sinus congestion, reducing the severity and frequency of allergy attacks. For example, vitamin C intake has been associated with a lower risk of developing allergy symptoms, and omega-3 fatty acids have been linked to a decreased risk of seasonal allergies. Additionally, food sensitivity testing can help identify underlying food sensitivities that may be contributing to allergy symptoms, allowing for targeted dietary adjustments to reduce inflammation. A balanced diet that includes a variety of fruits, vegetables, grains, legumes, and healthy fats, similar to a Mediterranean diet, is often recommended for overall health and allergy management.

What You'll Learn
Consume more vitamin C and omega-3 fatty acids
Consuming more vitamin C and omega-3 fatty acids can be beneficial in managing allergies.
Vitamin C, also known as ascorbic acid, acts as a natural antihistamine and antioxidant. It reduces the amount of histamine produced by the body, rather than blocking histamine receptors, which is how antihistamine medications work. Studies have shown that vitamin C may decrease inflammation, swelling, and related symptoms that occur at the site of an allergic reaction. A study on the effects of antioxidants in children with allergies found that participants who increased their vitamin C intake experienced fewer allergy symptoms. Another small study of 89 people with allergies or infectious diseases showed that those who received a 7.5-gram IV infusion of vitamin C had about 50% less histamine in their blood. The recommended vitamin C dose for allergic rhinitis is 2,000 mg per day, and it is considered safe and has a very low risk of toxicity. However, doses higher than 2,000 mg may cause gastrointestinal side effects, such as nausea, vomiting, or diarrhea.
Omega-3 fatty acids, including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are commonly found in fish oil. They are known for their anti-inflammatory properties and protective effects against inflammatory diseases, including asthma and allergies. Several reports indicate that a decrease in fish oil consumption in modern diets may be linked to the increasing number of individuals with asthma and other allergic diseases. Omega-3 fatty acids have been shown to counter-regulate airway eosinophilic inflammation and promote the resolution of inflammation. While the mechanisms of these effects are not yet fully understood, they hold great potential for therapeutic applications.
To incorporate more vitamin C into your diet, focus on consuming various fruits and vegetables, such as citrus fruits (oranges, kiwi, lemon, grapefruit), and tomatoes, which also have anti-inflammatory properties. For omega-3 fatty acids, include fish, such as salmon, sardines, and anchovies, in your meals, as well as plant sources like flaxseeds, chia seeds, and walnuts.
In addition to vitamin C and omega-3 fatty acids, other dietary and natural antihistamine approaches can help manage allergies. Consuming fresh, whole foods like fruits, vegetables, beans, whole grains, fish, and olive oil can help with respiratory allergies. Reducing salt intake and using herbs and spices for seasoning can also improve lung function. Turmeric, in particular, contains curcumin, which has anti-inflammatory properties and has been found to improve nasal airflow, reduce sneezing, and boost immunity. Butterbur, a plant extract, has also been traditionally used to treat hay fever and allergic rhinitis, but caution is advised due to potential allergic reactions and liver-related concerns.
It is important to remember that individual responses to dietary changes may vary, and severe allergies should be managed with the guidance of a healthcare professional. While natural remedies can be beneficial, always consult a doctor before trying new supplements or herbal treatments, as they can interfere with certain medications.

Reduce salt and processed food intake
Reducing salt and processed food intake can help alleviate allergy symptoms and improve lung function. Salt intake is often high due to the consumption of processed foods, which should be avoided or limited. To reduce salt intake, individuals can use fresh herbs and spices to season their dishes instead.
A diet low in sodium has been linked to lower urine sodium excretion, which may positively impact asthma symptoms. However, there is conflicting evidence regarding the direct impact of salt reduction on asthma and other allergic conditions. While some studies suggest a potential benefit in asthma management, others found no significant difference in asthma outcomes between low-salt and normal or high-salt diets.
In addition to reducing salt intake, following a comprehensive diet that includes certain foods can further help manage allergies. For example, a diet rich in vitamin C and omega-3 fatty acids has been associated with reduced allergy symptoms. Omega-3 fatty acids, found in fish, can be beneficial for respiratory allergies, and vitamin C has been linked to a lower risk of developing allergy symptoms.
Plant-based diets that emphasize fruits, vegetables, grains, and legumes while reducing animal food products have also been associated with reduced inflammation and a lower risk of allergic diseases. Calorie restriction, sufficient dietary fiber, and adequate macronutrient intake are essential for maintaining immune tolerance to allergens.
Overall, while reducing salt and processed food intake may not directly cure allergies, it can help improve respiratory function and overall health, making it easier to manage allergy symptoms when they arise.

Eat more anti-inflammatory foods
Diet and nutrition play a crucial role in managing allergic diseases by regulating tissue and immune homeostasis. Eating clean, fresh, and anti-inflammatory foods can help reduce inflammation and alleviate allergy symptoms. Here are some ways to incorporate more anti-inflammatory foods into your diet:
Increase Your Intake of Fruits and Vegetables
Fruits and vegetables are excellent sources of vitamins, minerals, and antioxidants, which can help reduce inflammation and support your overall health. Focus on consuming a variety of colourful fruits and vegetables, such as citrus fruits (oranges, kiwi, lemon, grapefruit), tomatoes, berries, grapes, apples, cabbage, cauliflower, onions, and dark, leafy greens. These foods are rich in vitamins, lycopene, and other nutrients with anti-inflammatory properties.
Include Healthy Fats and Omega-3 Fatty Acids
Omega-3 fatty acids have anti-inflammatory properties and have been linked to a decreased risk of allergy symptoms. Good sources of omega-3 fatty acids include fish, walnuts, flaxseed, and legumes. Additionally, almonds and cashews are high in magnesium, which helps reduce inflammation and supports various bodily functions.
Incorporate Turmeric into Your Meals
Turmeric is a spice commonly used in Indian cuisine, and its active component, curcumin, has powerful anti-inflammatory properties. Studies have shown that curcumin can improve nasal airflow, reduce sneezing and congestion, and boost immunity. Try adding turmeric to your diet by using it in smoothies, curries, or golden milk drinks.
Consider Probiotics and Prebiotics
Probiotics and prebiotics help promote a healthy gut microbiome, which is essential for regulating the immune system. While specific probiotics for allergy treatment require further research, studies suggest that they may positively impact allergy prevention and treatment. Prebiotics can be found in whole grains, onions, garlic, asparagus, and bananas. Probiotics are commonly found in fermented foods like yoghurt, kefir, sauerkraut, and kimchi.
Reduce Inflammatory Foods
While incorporating anti-inflammatory foods is essential, it is also beneficial to reduce your consumption of foods that can trigger inflammation. Refined carbohydrates, such as white bread and pastries, and excessive amounts of salt, which often come from processed foods, can contribute to inflammation. Instead, use fresh herbs and spices to season your dishes and opt for whole, unprocessed foods whenever possible.

Try a plant-based diet
A plant-based diet may be a good option to help alleviate allergy symptoms. This is because plant-based diets are anti-inflammatory, thanks to their high fibre, vitamin, and antioxidant content. Inflammation is a key factor in allergy symptoms, so reducing it through diet may help with symptoms.
Plant-based diets are also typically lower in histamine, a compound that can trigger allergy symptoms. Foods that are high in histamine include dairy products, fermented foods, and processed meats—all of which are avoided or reduced on a plant-based diet.
A plant-based diet may also help support a healthy gut microbiome, which is crucial for overall immune health. Research has shown that a diverse gut microbiome can help reduce inflammation and boost immune function, which may help alleviate allergy symptoms.
When following a plant-based diet for allergies, it's important to focus on whole, nutrient-dense foods. This includes plenty of fruits, vegetables, whole grains, legumes, nuts, and seeds. Specific foods that may be particularly helpful for allergy sufferers include apples, which are high in quercetin, a natural antihistamine, and leafy greens such as kale, spinach, and collard greens, which are high in magnesium, which has been shown to reduce allergy symptoms. Turmeric is another powerful anti-inflammatory that may help reduce allergy symptoms. Omega-3 fatty acids, found in flaxseeds, chia seeds, and walnuts, are also anti-inflammatory and can support immune function.
It is worth noting that while a plant-based diet can help reduce allergy symptoms, it may not be a cure. Additionally, some plant-based alternatives may not be suitable for those with nut allergies, as they often contain tree nuts. However, there are still many options available, such as sunflower-based alternatives, and increasing the percentage of plant-based foods in your diet can still be beneficial even if you cannot go fully plant-based.

Identify food sensitivities
Diet and nutrition play a crucial role in the development and severity of allergic diseases. While there are no official tests for food intolerances, there are ways to identify and manage them.
Firstly, it is important to understand the difference between a food allergy and a food intolerance. Food allergies are immune responses where the body produces an allergy antibody against a certain food. Common food allergies include milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans. Food allergies can be identified through a skin prick test or a blood test.
On the other hand, food intolerances are typically gastrointestinal issues that can be triggered by a lack of enzymes, genetics, or health issues such as irritable bowel syndrome (IBS). Food intolerances cannot be officially diagnosed, but an elimination diet is commonly used to identify trigger foods. This involves eliminating suspected foods and gradually reintroducing them to gauge their effect on the body.
To identify food intolerances, it is recommended to work with a healthcare professional or a dietitian. They can help design an elimination diet that suits your needs and guide you through the process of reintroducing foods. This ensures that you do not eliminate essential foods from your diet and helps you find a balanced diet that suits your biology.
Additionally, optimizing your gut health can be beneficial in managing food intolerances. Eating a diverse range of plant foods can help heal your gut and improve your gut microbiome, which may reduce food intolerances.
It is important to note that nutritional therapy holds promise in reducing allergy symptoms, and future clinical trials will further explore the link between nutrition and allergies.
