Bright Tots information on child development - Diet - Allergy Elimination Diet
|

Many children with autism have food sensitivities, due to abnormalities in their digestive and/or immune systems. If food is
not fully-digested into individual sugars, amino acids, etc., then the partly digested food can pass from the gastrointestinal
tract into the bloodstream. The immune system recognizes those foods as foreign, and may launch an immune response to
those foods, resulting in an allergic in behavior.
The most popular approaches are diets that eliminate foods containing either gluten or casein, or both. Removing allergic
foods can result in a wide range of improvements in some children, especially improvements in behavior and attention. This
diet is a temporary used to determine if a child has a potential allergy to certain foods by starting with a very basic diet low
in potential allergenic foods and intolerances.
In the elimination diet all suspected foods are removed for a period of time and then gradually reintroduced to observe any
response or reactions. If there is improvement, then try attempting the give the child one prohibited food every 5 days, to
see if any can be added back in. Gluten and dairy are the last challenged.
There are multiple tests for food allergies including blood and skin prick tests. However, there may be false negatives or
positives with these tests. Children with food allergies are at a higher risk for nutrition related problems and decreased
growth. Also, children with autism are more likely to be more negatively affected by problems with food allergies because
of their issues with sensory dysfunction.
While isolating food allergies or food sensitivity you may see an allergic reaction such as hives, runny nose, or
gastrointestinal symptoms like diarrhea or constipation. The following foods tend to be responsible for 90% of all allergic
reactions: milk*, wheat*, egg*, soy*, peanuts*, tree nuts*, fish and shellfish (*more commonly seen in children). The most
common reactive foods found in gluten include (wheat, rye, barley, possibly oats), dairy, cane sugar, corn, soy, yeast,
peanuts, egg, artificial colors and preservatives.
Eliminate the following foods from the diet for a period of 7 days:
• Dairy products, including cheese. (Instead, use soy milk and soy cheese; rice milk, rice-based ice cream.)
• Egg and egg-containing products.
• Food products containing gluten, such as wheat and wheat-based products (including pasta), and barley, oat or rye
grains. (Alternative grains could be brown rice, buckwheat, spelt, millet, potatoes or sweet potatoes).
• Citrus fruits.
• Corn and corn-containing products.
• All processed foods, including caffeine.
Next, reintroduce one food group to the child’s diet roughly every 5 days. The reintroduction period allows sufficient time
to determine any intolerance.
