Talking the talk about food allergies and symptoms.

Food allergies and GI issues have a language all their own, and it can be confusing and overwhelming. This glossary is here to help you understand the key terms and be better informed overall.

You can also visit our Symptom Guide to help you identify milk allergy and other GI-related symtpoms so you can discuss them with your doctor and dietitian.

  • Amino acid

    The basic building block of proteins. Amino acids link together in chains to form proteins.

    Amino acid Definition
  • Amino acid formula

    A hypoallergenic formula for infants and children where the protein is based on amino acids, the building blocks of protein. Amino acid formulas are effective in cow milk allergy (CMA), multiple food protein intolerance (MFPI) and other food allergy related conditions such as eosinophilic esophagitis (EoE), gastroesophageal reflux disease (GERD), atopic dermatitis or short bowel syndrome (SBS).

  • Atopy patch test

    An examination to determine sensitivity to a specific allergen. It is performed by laying a patch soaked in a particular allergen on the patient's skin. The test is positive if the skin where the patch was laid shows irritation. These tests are often considered not 100% accurate.
