@msrobotics Dear Friend, I have had OAS for over two years now and can tell you it's very complicated. It's more than just raw fruits, vegetables, and nuts. It's how your food is processed, stored, and cooked. For example, the coffee bean would be a typical allergen for us. However, it goes through so much transformation to end up in the ground state, that your immune system will never be able to read its protein and mistake it for a tree pollen. So I do lots of reading on MS Copilot (or any AI tool) to determine what's safe for me. Another example is bread. As long as it's white and has been thoroughly cooked, it might be safe. That's because there are no granules left that contain pollen like multi-grain bread. Best of luck!
@msrobotics As Lucy mentioned, I have some familiarity with oral allergy reactions - my daughters, brother, sister and I each react to quite dramatically to different foods, as do a number of nieces and nephews.
My triggers are wheat, tree nuts and sweet peppers. My sister's are apples and stone fruits - but only if raw. My brother reacts to dozens of foods and has a SEVERE ragweed allergy that has landed him in the hospital.
The pollen concept is new to me, but makes sense. As a kid, I reacted severely in any barn where wheat straw was used, but had no reaction to Timothy hay, barley, oat or rye straw. As for diet, I tolerate oats, barley, buckwheat and Spelt, but NO wheat in any form. We have not found an uncontaminated source of rye to try. I look forward to reading more about this concept.
@msrobotics - tagging a Mayo Clinic Connect member who has mentioned pollen-food-allergy syndrome (PFAS) or oral allergy syndrome so they can comment on if they have found that an entire group of foods related to the allergen is off limits @jwfletcher. @mgnunez75 @rebaba @sueinmn @terrirussell @leannekolo21 @oceantroll @madvzebra also may be familiar with this syndrome and have some input for you.
