Casein Allergy

[Updated March 2, 2016]

What is a casein-free diet?

A casein-free diet has been found to be beneficial for a number of people for a variety of reasons.

Casein is a protein found in mammal milk. It is commonly found in cow (and other bovine) milk, and human breast milk. You may have a casein allergy or sensitivity if you have swollen lips, develop hives, or other symptoms.

A gluten-free and casein-free (GF/CF) diet has provided positive results for many people diagnosed with an autistic spectrum disorder, such as autism, Asperger’s syndrome, atypical autism and pervasive developmental disorder.

Currently, there are no double-blind studies proving the efficacy of the GF/CF diet in autistic spectrum disorders. Several open studies conducted in Europe and the United States do provide strong positive data. There is also voluminous anecdotal evidence on the efficacy of the dietary approach.

When removing dairy from the diet, it is vital that adequate calcium and vitamin D be added in the form of fortified milk substitutes or acceptable vitamin and mineral supplements. Guidance from a qualified physician or nutritionist is strongly advised.
