That's what I gather from my sniffling, sneezing coworkers. Accuweather.com says dust and dander levels are high now. Huh. I suffered so long and so badly with allergies that it's strange to feel fine while others are going around with sinuses packed tighter than a 200-pound woman in size eight pants. Since I started a wheat-free diet, I've been mostly free of allergies. (My hay fever last year might have been brought on by drinking almond milk laced with carrageenan, a thickener and inflammatory. If your sinuses are inflamed, it won't take much mucus to fill them up.) I also don't use any dairy besides butter; it can cause congestion. To paraphrase an old saying, nothing tastes as good as a clear head feels.
Do-it-yourself health. Low-carb, mostly evolutionary.
