As you know I'm allergic to soy products and mostly make my own food from scratch to avoid them.I had already noticed when I ate cooked eggs I almost always got a tummyache (spasms and acid-like pain), so I had stopped doing that. Beginning last summer I didn't eat anything made with eggs for several months because it was too warm to bake. I made yeast breads with my bread machine instead.Then I made a salmon loaf with 2 eggs, eating some every day for 4 days (I froze it in individual portions). I was tired all week and the afternoon of the third day got a sinus headache that persisted for another 3 days. I recognized this as a food allergy reaction - I always get worse reactions to food than to environmental - and going over what I'd been eating found the only new thing was the eggs.Then I remembered I had tested positive for egg allergy as a child, but my "doctor" rationalized that cooked eggs would be ok for me, and my parents never taught me to avoid eating eggs.Luckily there are some simple egg substitutes in Dr. B's book, and I've been able to make baked things with them. I've been egg-free for 2 weeks and feeling as good now as I did in those months when I coincidentally didn't eat any eggs. Also I've had a cold, but the congestion isn't nearly as bad as I usually get with colds. I suspect eggs are the reason I've had 2 sinus infections in the last year.Hopefully no more!!
