❓How many times have I been asked if children should avoid chicken if they are allergic to eggs?
❗Not as often as parents telling me their child is allergic to chicken meat or start sneezing when there is either cooked eggs or cooked chicken around.
⁉️Can this really happen?
✔Actually, it can, but we need to understand that 𝘢𝘭𝘭 𝘢𝘳𝘦 𝘳𝘦𝘭𝘢𝘵𝘪𝘷𝘦𝘭𝘺 𝘳𝘢𝘳𝘦.
Chicken Allergy can be primary or secondary; this one often called Bird Egg Syndrome.
✳But let us take this into the several aspects that might cause any of the above symptoms.
➡️The main difference between the two types is that the primary kind is associated with a protein called 𝘎𝘢𝘭 𝘥 𝟽 and the second called 𝘎𝘢𝘭 𝘥 𝟻.
What does it mean?
✴𝐆𝐚𝐥 𝐝 𝟕 is 𝘩𝘦𝘢𝘵 𝘴𝘵𝘢𝘣𝘭𝘦 (long term allergy), and 𝐆𝐚𝐥 𝐝 𝟓 is 𝘩𝘦𝘢𝘵 𝘥𝘦𝘨𝘳𝘢𝘥𝘢𝘣𝘭𝘦 (very likely to outgrow the egg or chicken meat allergy).
🔻The symptoms vary, according to age group:
▶️In adults, the signs are usually respiratory associated (asthma or wheeze) or affect the eyes or nose (rhinoconjunctivitis).
▶️In children, it will mainly affect the gastrointestinal tract or leading to breathing problems.
👫Children with egg allergy and respiratory symptoms related to bird egg syndrome, tend to either acquire tolerance later or not outgrow it.
𝘜𝘴𝘶𝘢𝘭𝘭𝘺, 𝘴𝘺𝘮𝘱𝘵𝘰𝘮𝘴 𝘴𝘵𝘢𝘳𝘵 𝘭𝘢𝘵𝘦𝘳 𝘪𝘯 𝘵𝘩𝘦𝘪𝘳 𝘭𝘪𝘷𝘦𝘴.
⛔As with egg allergy, be aware of the cross-reactivity between chicken meat and turkey meat.
🚫But there can also be reactions to duck or goose meat, 𝘵𝘩𝘰𝘶𝘨𝘩 𝘵𝘩𝘦 𝘳𝘦𝘢𝘤𝘵𝘪𝘰𝘯𝘴 𝘵𝘦𝘯𝘥 𝘵𝘰 𝘣𝘦 𝘮𝘪𝘭𝘥𝘦𝘳.
So you will need to avoid all those meats until a proper diagnosis is made.
