Itchy skin can be a sign of allergy or intolerance
How are allergy and intolerance different?
Allergy and intolerance are different, but they’re also very similar. Both are caused by an immune reaction, but the difference is in the timing. Allergy is immediate and intolerance is delayed, making it harder to pinpoint the offending food. Allergic reactions release histamine, which is why they show up on skin-prick tests, while intolerances don’t necessarily. But the cause is similar – a food protein (allergy) or a food chemical (intolerance) and so are the symptoms – a rash, stomach complaints, breathing difficulties etc. However, allergy can be life-threatening, so I’m sure we all agree it cannot be ignored. Intolerance, on the other hand, may lead to life-long illness, so maybe it’s about time we paid it some more attention!
