What is it?
This diet removes gluten, the milk protein casein and soy. It combines three different elimination diets and is one of the most restrictive approaches commonly promoted to autism families.
Foods removed:
Wheat, barley, rye, regular bread and pasta; milk, cheese, yogurt, butter, whey and casein; and soybeans, tofu, soy milk, soy protein and foods containing soy-derived ingredients.
Potential health benefits:
It may help a child who has one or more confirmed conditions such as celiac disease, wheat allergy, cow’s-milk protein allergy or soy allergy.
Who may benefit most?
Children with diagnosed reactions to the ingredients being removed. Eliminating all three categories without evidence of a medical need may unnecessarily reduce the child’s food choices.
How may it support an autistic child?
Research on GFCF diets and autism is mixed. Some families report changes, but better-quality studies have not found consistent improvement in core autism characteristics. Addressing a genuine allergy or gastrointestinal condition may improve comfort and quality of life.
Important nutrients to replace:
Calcium, vitamin D, protein, iron, fiber and B vitamins. Professional supervision is strongly recommended.
