Hi I am a 42 year old woman. As a child I was always prone to allergies.  Milk in particular - nausea, vomiting , etc.  I fell pregnanet 9 years ago and during my pregnancyI was diagnosed with type 1 Diabetes.  My thyroid also stopped working. A year ago I contracted alopecia aratea.  I have been having more dairy products in the last year, could all my auto immune dysfunctions be caused by food allergies such as a milk allergy?

Summarized question: Are auto immune dysfunctions caused by food allergies?
