Key Takeaways
  • Improving hay fever and chronic allergies is fundamentally about 'reducing' rather than 'adding.'
  • The 6 main types of foods to avoid are: excessive omega-6, fried and burnt foods (acrylamide), food additives, highly refined carbohydrates, oxalates, and gluten.
  • Excessive intake of vegetable oils and fried foods, and frequent consumption of processed foods, may promote inflammation (supported by related research).
  • Consider alternatives such as olive oil, avocado oil, fish-derived omega-3s, minimally processed foods, and low-temperature cooking.
  • If symptoms are severe or when starting dietary restrictions, it is important to consult a doctor or specialist.

Introduction: Relieving Hay Fever and Chronic Allergies Through Subtraction

Rather than thinking of 'curing' hay fever and chronic allergies with diet, it's more realistic to first reduce the factors that worsen symptoms. We've experienced firsthand how simply reviewing our daily diet can alleviate sneezing and itchy eyes. This article clearly introduces 6 types of foods to actively avoid, along with their reasons and practical alternatives.

Foods to Avoid #1: Excessive Omega-6 (Linoleic Acid)

Why Avoid It

Omega-6 (linoleic acid), abundant in corn oil, sunflower oil, and safflower oil, is prone to converting into inflammatory substances in the body and has been suggested to strengthen immediate allergic reactions mediated by IgE antibodies. Trans fats found in margarine and shortening have also been implicated not only in cardiovascular risk but also in allergy risk (based on past epidemiological and pediatric studies).

Practical Measures

Try switching cooking oils to olive oil, avocado oil, quality butter or ghee, and coconut oil. Additionally, balancing the omega-3/omega-6 ratio with blue fish or omega-3 supplements can be beneficial (be mindful of heavy metal contamination and quality).

Foods to Avoid #2: Fried and Burnt Foods (Acrylamide and AGEs)

Why Avoid It

Acrylamide, generated during high-temperature cooking, has been linked to allergy-related symptoms in animal studies and epidemiological data. Furthermore, oils used for frying are prone to oxidation when heated, increasing harmful components. Burnt or excessively browned foods increase AGEs (Advanced Glycation End-products), contributing to chronic inflammation.

Practical Measures

Reduce the frequency of fried foods and increase steaming, boiling, or low-temperature oven cooking to lessen the burden. If you must fry, thoroughly manage the oil temperature and avoid reusing oil.

Foods to Avoid #3: Food Additives (Colorings, Preservatives, Emulsifiers, etc.)

Why Avoid It

Cases have been reported where colorings, preservatives, emulsifiers, artificial sweeteners, and the like are associated with worsening chronic urticaria, atopic dermatitis, and itching. Since they are often found in processed foods, convenience store meals, and snacks, people tend to consume them unknowingly.

Practical Measures

First, check food labels and choose foods with short, simple ingredient lists. Reducing additives through homemade meals and simple cooking is also effective. When eating out, it's good practice to ask for 'fewer additives.'

Foods to Avoid #4: Highly Refined Carbohydrates (Sugar, White Rice, Sweets)

Why Avoid It

Refined carbohydrates can promote histamine release and increase inflammatory cytokines, potentially worsening allergy symptoms. Rapid blood sugar spikes also affect immune balance.

Practical Measures

Instead of sugar, white bread, and sweets, incorporate whole grains, fruits, and nuts to help moderate post-meal blood sugar fluctuations.

Foods to Avoid #5: High-Oxalate Foods

Why Avoid It

Oxalates, abundant in spinach, rhubarb, and nuts, have been reported to potentially cause inflammation of the eyes, mouth, and skin. Particularly sensitive individuals may experience symptoms.

Practical Measures

If you are concerned about oxalates, you can reduce their absorption by blanching them during cooking, adjusting intake frequency, or consuming them with calcium.

Foods to Avoid #6: Gluten (for Sensitive Individuals)

Why Avoid It

While gluten triggers an immune response in celiac disease, non-celiac gluten sensitivity has also been linked to immune and intestinal inflammation. Evidence varies greatly among individuals, and it does not apply to everyone.

Practical Measures

It's recommended to first observe your own reaction with a short-term gluten elimination trial. If symptoms improve, consider continuing and consult a specialist to ensure nutritional balance is not compromised.

Daily 'Subtraction' Habits and Precautions

From our own experience, simply 'limiting fried foods to once a week or less,' 'using olive oil as the primary cooking oil,' and 'reducing processed foods to less than half of our weekly intake' significantly eased our eye and nasal discomfort. The key is not extreme elimination, but small, sustainable reductions. Also, ensure adequate intake of protein, essential fatty acids, and vitamins to avoid nutritional deficiencies. Individuals with severe allergies or pre-existing conditions, as well as pregnant or breastfeeding individuals, should make dietary changes under the guidance of a doctor.

Summary

For improving hay fever and chronic allergies, 'subtraction' is more effective than 'addition.' By reducing factors such as excessive omega-6, fried and burnt foods, food additives, highly refined carbohydrates, oxalates, and gluten, it's possible to lessen the inflammatory burden. Incorporate alternatives like olive oil, blue fish, minimally processed ingredients, and low-temperature cooking to aim for sustainable eating habits. If symptoms are severe or when starting dietary restrictions, it's safest to consult a doctor or registered dietitian.
