All You Need to Know about Banana Allergy in Babies

What is it?

A banana allergy is an allergy to certain proteins present in bananas. The baby will have a banana allergy if the immune system is hypersensitive towards a specific protein found in it. If the baby has an allergy to bananas then this means that once consumed, the body will attack the food to protect the digestive system by sending out white blood cells. This can provoke an external allergic reaction in the baby.

Causes of Banana Allergy in Babies

If the baby vomits or has a red rash on the face soon after eating a banana, it may be because of a banana allergy. This might happen due to the following causes –

  • Protein intolerance – there is a protein found in bananas which is called ‘chitinase’. The baby’s immune system may be tolerant to this protein and hence become hypersensitive causing an allergic reaction to bananas.
  • Vasoactive amines – bananas contain a substance known as vasoactive amines. Vasoactive amines are similar to histamines and occur naturally. If the baby’s metabolic system cannot oxidise enzymes, then vasoactive amines may lead to an allergy to bananas in babies.
