Change Your Diet; Improve Your Allergies
More than 45 million Americans suffer from seasonal allergies. Dietary factors impact the course of seasonal allergies. Indeed, your diet can make your allergy symptoms worse or better. So what changes can you make to help your symptoms?
Eat at Least 2 Servings of Omega-3 Rich Foods Daily
A deficiency of these special fatty acids increases the risk of allergies. Walnuts, chia seeds, spinach, soybeans, and ground flaxseed are good vegetarian sources of essential anti-inflammatory alpha linolenic acid. We do not recommend the consumption of fish for omega-3 fats. Why? Fish is a common food allergy. Because of a process known as bio-magnification, fish are known to accumulate toxins and pesticides. Evidence shows pesticides disrupt the balance of the immune system so essential in the prevention of allergies and autoimmune diseases.1 Fish are especially known to contain pesticides. The highly toxic dioxins are another environmental polluter which accumulate in fish and can cause damage to the immune system.
Emphasize Foods Containing LOX Inhibitors
LOX enzymes are involved in the production of pro-inflammatory leukotrienes, which are key contributors to allergies and asthma. Please note: arachidonic fatty acid is the precursor of leukotrienes. Inhibitors reduce their formation. Fortunately, a wide variety of plant foods contain LOX inhibitors. Anthocyanins, the phytochemicals that compose the purple, red, and blue pigments in foods, are natural LOX inhibitors. Certain phytochemicals from pomegranates, garlic, onions, sesamin from sesame seeds, and resveratrol in red grapes and blueberries, inhibit both leukotrienes and another pro-inflammatory enzyme called COX-2.
Avoid Dietary Bloopers
Reduce consumption of omega-6 fats (including corn, safflower, sunflower, or peanut oils). Excessive use of these fats, as opposed to omega-3 ones, tends to increase inflammation in the body. One study found positive associations between hay fever and arachidonic acid.2 Sources for arachidonic fatty acids include meat, eggs, and fish. Seriously limit sugar; it shifts body chemistry toward inflammation.
Probiotics May Help
There is early evidence that probiotics may help allergies in some cases.3 Further investigation is warranted, but it might be worth a try.
When Good Foods Aggravate Seasonal Allergies
Sometimes even good food can intensify seasonal allergies. According to Dr. Joseph Leija, “Those with grass allergies should avoid melon, tomatoes, and oranges. Ragweed allergies are also linked to allergies to bananas, cantaloupe, cucumber, zucchini, and chamomile tea. The spring allergy count in the Midwest is high in birch and oak, which usually triggers reactions to carrots, celery, almonds, apples, peaches, and pears in those with sensitive systems.”4 We would be amiss if we did not mention that food allergies can give not only gastrointestinal symptoms but can also impact the respiratory system. So, if you have respiratory symptoms during the entire year, food allergies are a possibility that should be explored.
Rosemary, Sage, and Basil
The rosmarinic acid in each of these common herbs reduces inflammation in the sinuses and lungs. Unlike antihistamines, rosemarinic acid suppresses pro-inflammatory responses and decreases the activation of immuno-responder cells that promote swelling and other symptoms of allergy- induced inflammation.5,6 However, pregnant or lactating women should not use medicinal amounts of rosemary or sage. If you are taking any medications, be sure to check with your pharmacist before using herbs in medicinal amounts so as to avoid any potential adverse drug-herb interactions.
The herb, stinging nettle, contains naturally occurring antihistamine, and studies suggest that it can be moderately effective in reducing allergic symptoms.7 It is generally regarded as safe. However, since the fresh plant can irritate the skin, pick nettles with caution and/or protection, or better yet, get it in capsule form. Vitamin C, quercetin, and pine bark also contain natural antihistamine agents.8 Unlike many pharmaceutical drugs, these naturally occurring substances will not cause drowsiness.
Is Your Vitamin D Adequate?
Vitamin D is an important immune-regulator and a natural anti-inflammatory agent. Be sure you are not deficient in this essential vitamin. The main vitamin D metabolite, calcitriol, suppresses development of the Th-1 cells. Th-1 cells are a type of helper T-lymphocytes. When they become overactive, they play a key role in allergy development. Evidence indicates that vitamin D deficiency may play a major role in the development of allergies.(9, 10)9,10 Sunlight exposure is a precursor to vitamin D synthesis in the body. When weather permits, daily exposure on the skin without sunscreen application is most valuable. The amount of time needed depends on skin color and the intensity of the sun. One caveat: Since vitamin D insufficiency is common in North America and Western Europe, if you have allergies, have your vitamin D level checked. It is a simple blood test. Although a deficiency in vitamin D needs to be corrected, vitamin D supplementation does not cure seasonal allergies, but it may possibly help reduce some allergic reactions.
Nothing to Sneeze at
Seasonal and other common allergies can contribute to chronic coughing, ear infections, inflammation of the esophagus, deficient sleep, intensified asthma symptoms, and possible increased risk for stroke. If these suggestions and natural remedies do not provide significant relief, we would recommend seeing an allergist or ENT (ear, nose, and throat) specialist.
