A study by Lucarelli et al found that an 8-week diet that avoided allergic foods resulted in benefits
in an open study of 36 children.

Three studies have demonstrated that children and adults with autism often have low levels of
digestive enzymes for sugars and carbohydrates, especially the sugar in milk, which reduces the
ability to digest those foods (see section on Digestive Enzymes).

Three studies have demonstrated that some individuals have increased intestinal permeability, so
that large sugar molecules that normally would not be absorbed are able to pass through the
intestinal wall into the blood stream. This “leaky gut” may allow other partly digested foods to pass
into the body, potentially causing an allergic or immune response to those foods.
It is unclear if
this test for sugars is relevant to proteins since they are absorbed by a different mechanism.

There are many studies of gastrointestinal problems in children and adults with autism (see reviews
by Buie et al 2010 and Coury et al 2012), and inflammation of the gut will greatly increase the
likelihood that the immune cells in the gastrointestinal tract will react to foods.

Limitations of IgG blood testing
Two studies found that IgG blood testing was not clinically relevant to the general population for
identification of food allergies.

cannot be diagnosed based on IgG subclass orIgA responses to milk allergens. Allergy 66, 1201-1207.
