On this episode of The Whole View podcast, Stacy and I dive into the science and details of environmental allergies. I first describe the mechanism of the IgE-mediated release of histamine, and how it compares with other intolerance and allergic reactions. We discuss the four main categories of environmental allergens: dust mites, animals, pollen and mold. Oh, and also we definitely don’t talk about the fifth most common…let’s just say, EWWW, no thanks!! Stacy learns the true science behind dust mites which changes her understanding, and we also distinguish between the areas of chemical sensitivity, and environmental allergy (which are not at all the same mechanism, btw!).
I dive into the ways that most practitioners complete testing for environmental allergies, as well as some of the vitamins that seemingly support the body through all of this histamine processing. Most notably, vitamins D and E have been shown to be quite important and effective for supporting allergies, and omega-3 also, the king of anti-inflammatory supplements can also support. Always remember that you should definitely talk to your doctor about any supplementation (especially vitamin D and E, as there are toxicity levels and contraindications with other medications). Another surprising fact that recent studies have uncovered, is that a high-fat diet is particularly bad for allergy conditions! If you are a seasonal or environmental allergy sufferer, there are lots of helpful tips and solutions both in natural and medication forms. Consider consulting with your doctor about the proper use of over-the-counter antihistamines (the second generation of which are quite fascinating and super helpful), as well as consider an allergy shot, which helps to improve the immune tolerance over small exposures through time.
