Hay fever, also termed allergic rhinitis, results when your body has an allergic reaction to pollen, pet dander, dust or other elements of the environment. Symptoms of hay fever include uncomfortable symptoms like congestion, sneezing, itchy, watery eyes and a runny nose. No official diet exists to treat hay fever, however certain dietary changes might influence the improper immune response that triggers the allergic reaction. Consult with a knowledgeable health care practitioner before making any drastic dietary changes or following alternative unfounded diets, particularly those that call for large doses of supplements.
Probiotic-Rich Foods
Probiotics---the healthy bacteria that reside in your intestines---contribute to better health in several ways. One role, promoting healthy immune function, might benefit hay fever and other conditions influenced by improper immune response. Probiotic-rich foods include yogurt, fermented soy foods like miso and tempeh, sauerkraut, kefir, kimchi---a fermented cabbage dish popular in Korea. You can also take probiotic supplements that contain these beneficial bacteria in concentrated amounts. The Mayo Clinic notes that sufficient evidence does not exist to support these claims; however the University of Maryland Medical Center, or UMMC, notes one study showed that the probiotic L. acidolphilus reduced the allergic reaction to pollen.
Low-Protein Foods
Integrative medicine expert Dr. Andrew Weil recommends limiting your protein intake, and particularly animal proteins, if you suffer from hay fever. Dairy products in particular is discouraged. Weil notes that eating large amounts of protein can aggravate the immune system; and that casein, the protein found in milk, is one of the most common irritants. Protein is required by the body for normal function; focus instead on increasing intake of plant-based sources such as whole grains, beans and soy foods rather than refined white flour foods and sugar-rich items.
Nutritional Supplements
In addition to your diet, certain nutritional supplements may benefit hay fever. Quercetin, a substance found in many fruits and vegetables, appears to block the release of histamine, an inflammatory substance involved in an allergic reaction. Weil recommends taking 500 mg daily for six to eight weeks. The UMMC notes that the algae spirulina also has an antihistamine effect, but confirmation of benefit requires more research in people. Vitamin C might protect against hay fever but studies have produced mixed results.
