What Is Soy Allergy In Children?

Soy comes from soybeans which is a member of the legume family. The same family from which, peas, lentils, beans, etc. comes from. Some children develop an allergy to more than one kind of legume or some may develop an allergy to only soy. The child who develops an allergy to soy doesn’t necessarily means he has increased the chance of developing allergic to other members of the legume family, like the peanuts etc. Soy allergy happens when your baby’s immune system regards certain proteins found in soy as invaders that may be harmful to the body. Once your child’s immune system decides that soy protein is dangerous, it generates antibodies to fight against it. So the next time when your child eats or drinks any soy product, his immune system discharges substantial quantities of chemicals which also include histamine, in order to guard his body. This is when the soy allergy takes place.

Does All Soy Products Cause Allergy?

Some soy foods that are fermented such as, shoyu (soya sauce), miso (a Japanese seasoning) and tempeh (an Indonesian soy product in which soybeans are bound into a cake form) are found to cause less allergy as compared to whole soybeans. This is because the process of fermentation partially breaks down the allergy causing proteins.
