Limit Allergen Exposure: Using an air filter, preferably one that ties into a central heating and air conditioning system, can drastically reduce the build-up of allergens in your home. Pet areas, carpets, rugs, and upholstered furniture should be cleansed regularly, and bedding should be washed at least once a week.
Avoid These Foods: Foods that have been closely linked to respiratory allergies include dairy products, chocolate, sugar, and gluten. There is also strong evidence suggesting that certain food additives, including artificial dyes and colorants, sulfites, and benzoates, are culprits.
Eat These Foods: Intake of omega-3 fatty acids has also been shown to support healthy airways and encourage the production of anti-inflammatory mediators. Also consider onions and garlic, ginger, rosemary, curcumin (turmeric), and the herb boswellia.
Get Your Antioxidants: Increasing intake of antioxidants is also essential to prevent the free radicals which are often elevated in allergies and asthma. This includes vitamins C and E, selenium, carotenoids, and flavonoids. Bromelain, an enzyme, can also help.
