I am a personal trainer and not a doctor, however I have read the book by Natasha Turner, The Hormone Diet, this has an explanation of how hormones affect the immune system. I would try getting this book and reading it. I have had allergies for years, started with asthma as a child but grew out of it, I eliminated wheat gluten and dairy from my diet my allergies subsided for the first time in my life. Start with the Anti-Inflammatory detox first and slowly add foods back to the diet. The detox triggered an allergic reaction in the middle of January for me, it only lasted about 24 hours. This has never happened before, I believe it was my body rejecting toxins that had built up over time in my body.
Charles Poliquin is a world class trainer that has many articles on supplements and vitamins among other things check out his site for some insights into asthma and allergies.
