It could be both sugar and grains that make you susceptible to inhalant allergies. I have been off of sugar since the mid-1990s, but continued to eat grains until starting the PB in June of this year. During that time, I suffered from seasonal allergies just like I had since childhood. Since going primal, the allergies have just about disappeared. Just a little sniffle once in a while, even when dust or pollen is at a high level. Methinks grains, at least in my case, are the culprit.
Live your life and love your life. It's the only one you get.
