Identifying and Addressing Food Sensitivities in Autistic Children

Identifying and Addressing Food Sensitivities in Autistic Children

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition that affects children in various ways. While there is no one-size-fits-all approach to addressing the needs of autistic children, recent research has shed light on the relationship between autism and food sensitivities. Many parents and caregivers have reported improvements in behaviour and overall well-being in autistic children when specific dietary changes are made. In this blog, we will explore the concept of food sensitivities in autistic children, how to identify them, and strategies to deal with them.

Understanding Food Sensitivities

Food sensitivities, also known as food intolerance, occur when the body has difficulty digesting certain foods. Unlike food allergies, which involve the immune system, food sensitivities are often related to digestive issues. Common symptoms of food sensitivities include gastrointestinal problems, skin issues, mood swings, and changes in behaviour. In autistic children, these sensitivities can manifest differently, making them challenging to identify.

Identifying Food Sensitivities in Autistic Children

1. Keep a Detailed Food Diary:

Start by maintaining a detailed food diary that tracks everything your child eats and drinks, along with their behaviour and any physical symptoms. Look for patterns or correlations between specific foods and changes in behaviour or mood.

2. Consult a Healthcare Professional:

It’s essential to work closely with a healthcare professional, preferably a paediatrician or a registered dietitian, experienced in autism and dietary issues. They can help you interpret the food diary and recommend appropriate tests if necessary.

3. Elimination Diet:

Under the guidance of a healthcare professional, consider implementing an elimination diet. This involves removing potential trigger foods from your child’s diet for a specified period and then gradually reintroducing them to see if there are any adverse reactions.

4. Genetic Testing:

In some cases, genetic testing may be beneficial. Certain genetic factors can make a child more susceptible to food sensitivities. This information can help customize dietary interventions.

Addressing Food Sensitivities

1. Gluten-Free and Casein-Free Diet (GFCF):

One of the most commonly discussed dietary interventions for autistic children is the GFCF diet. This involves eliminating gluten (found in wheat, barley, and rye) and casein (found in dairy products) from the diet. Some parents report improvements in behaviour, communication, and gastrointestinal issues when implementing this diet. However, it may not work for every child, and it’s crucial to consult a healthcare professional before making such significant dietary changes.

2. Individualized Approach:

Remember that there is no one-size-fits-all solution. What works for one autistic child may not work for another. It’s essential to tailor dietary interventions based on your child’s specific needs and sensitivities.

3. Nutrient-Rich Diet:

Ensure that your child’s diet is well-balanced and rich in essential nutrients. Nutrient deficiencies can worsen behavioural and developmental issues. Consider consulting a dietitian to create a customized meal plan that meets your child’s nutritional requirements.

4. Monitor Progress:

Continuously monitor your child’s progress and document any changes in behaviour, mood, or physical symptoms and share them with your healthcare professional to make informed decisions about dietary adjustments.

Identifying food sensitivities and allergies in autistic children in India

In India, identifying food allergies and sensitivities typically involves a combination of clinical evaluation, medical history assessment, and specific tests.

Here are some of the common tests and approaches:

1. Clinical Evaluation:

A healthcare professional, such as a paediatrician or allergist, will conduct a thorough clinical evaluation of the child, taking into account their medical history, symptoms, and family history of allergies or sensitivities. They will also assess the child’s growth, development, and overall health.

2. Skin Prick Test (SPT):

This is one of the most common allergy tests used in India. It involves pricking the skin with a tiny amount of allergen extract (e.g., common food allergens like peanuts, dairy, or eggs) and observing for localized skin reactions. A positive reaction indicates sensitivity or allergy to that specific allergen.

3. Blood Tests:

Blood tests, such as specific IgE (immunoglobulin E) tests, can measure the levels of IgE antibodies in the blood in response to specific allergens. A higher level of IgE antibodies to a particular food allergen may suggest an allergy. Common blood tests used in India include ImmunoCAP and ELISA-based tests.

4. Food Diary and Elimination Diet:

Keeping a detailed food diary, as mentioned earlier, can help identify patterns between food intake and adverse reactions. Under the guidance of a healthcare professional, an elimination diet can be implemented to remove and reintroduce potential trigger foods to observe changes in symptoms.

5. Oral Food Challenge:

In some cases, a controlled oral food challenge may be conducted under medical supervision. Small, increasing doses of a suspected allergen are given to the child, and any allergic reactions are closely monitored.

6. Patch Testing:

Patch testing is typically used for diagnosing contact dermatitis but may also be used to identify food sensitivities when other tests are inconclusive. It involves applying allergen-containing patches to the skin for a specified period and checking for delayed skin reactions.

7. Endoscopy and Biopsy:

In severe cases of gastrointestinal symptoms or suspected eosinophilic esophagitis, an endoscopy and biopsy may be performed to assess the presence of inflammation or damage to the oesophagus or stomach.

8. Food Allergy Panel:

Some diagnostic laboratories in India offer comprehensive food allergy panels that test for a wide range of food allergens simultaneously. These panels can provide a broader picture of potential allergens.

It’s important to note that testing for food sensitivities and allergies in autistic children should be done under the guidance of a healthcare professional with experience in both autism and allergies. Additionally, it’s crucial to consider the child’s needs and symptoms of each child, as well as their unique dietary requirements. Dietary modifications, if needed, should be made cautiously and with professional guidance to ensure balanced nutrition.


Identifying and addressing food sensitivities in autistic children can be a challenging but potentially rewarding journey. It’s essential to approach dietary interventions with caution, seeking guidance from healthcare professionals and considering your child’s unique needs. While dietary changes may not be a cure for autism, they can contribute to improved overall well-being and quality of life for some autistic individuals. Remember that patience and persistence are key when exploring dietary interventions, and always prioritize your child’s health and happiness above all else.
