Birdy, when I was allergy tested back in 2000, I reacted to coffee and slightly to black tea too. I have no idea what in the coffee I reated to. I'm a person who has hives quite often and so I never know what is going to set them off. When I was tested, I broke out so much that they had a hard time telling what foods I was reacting to and how much.
I really like coffee but gave it up after that, as well as many other foods/beverages and since following this program for the past 5 + yrs., the hives are better, but I still have them. Of course, I can rub my skin the wrong way and break out!
I usually drink herb teas and like them very much. I love rooibos (red) tea now. Most people have to acquire a taste for it, which I have. I like it with vanilla in it. I don't drink tea every day though. My main beverage is water and I drink lots of it daily.
You also mentioned dairy. To me, dairy is one of, if not the
most detrimental food humans consume. I'm allergic to it and I always know if I happen to ingest any if I'm eating away from home. It causes me hives, gastric distress, sinus congestion & brain fog. Because it makes me feel ill, I have no desire for it.
I wish that I could develop that same feeling for oils!!
I need to be more diligent in keeping them out of my diet when away from home, and it's so hard.
