Ingredients to Avoid for Children with Autism Spectrum Disorder

By Dr. Tahani Williams M.D.

Raising a child with autism spectrum disorder (ASD) often means paying closer attention to what goes into and onto their body. Many parents notice that certain food ingredients, medications, or personal care products may worsen behavioral challenges, gastrointestinal discomfort, sleep disturbances, or sensory sensitivities.

While every child with autism spectrum disorder is unique, becoming informed about ingredients to avoid can help parents identify potential triggers and make more confident choices. Although research is still evolving, reducing exposure to known irritants and suspected triggers may support overall comfort and daily functioning for some children (1)(2).

This article explores commonly avoided ingredients linked to autism-related sensitivities, explains why they may pose concerns, and highlights safer alternatives – including personal care options designed for sensitive children. Parents considering dietary or product changes should always consult a healthcare provider or registered dietitian before starting an elimination plan.

Learn how to read an ingredient label, to help you identify the harmful ingredients below.

1. Artificial Food Additives

Artificial Colors
Examples: Red 40, Yellow 5, Yellow 6, Blue 1
Why Avoid: Synthetic food dyes have been associated with increased hyperactivity, attention challenges, and sensory overload in some children (1)(2).
Where Found: Candy, cereals, sodas, flavored medications.

Artificial Preservatives
Examples: Sodium benzoate, BHA, BHT
Why Avoid: These preservatives may irritate the nervous system and contribute to behavioral changes in sensitive children (1).

Artificial Sweeteners
Examples: Aspartame, sucralose
Why Avoid: Artificial sweeteners may disrupt gut balance and trigger mood or behavior changes in some children with ASD (6).

2. Excess Refined Sugar & High-Fructose Corn Syrup (HFCS)

Why Avoid: High sugar intake can contribute to irritability, energy crashes, and gut microbiome imbalances, which may exacerbate behavioral challenges (6).
Where Found: Sodas, flavored yogurts, cereals, snack bars.

3. Gluten and Casein (GFCF Diet Considerations)

• Gluten: Found in wheat, barley, rye
• Casein: Found in dairy

Why Avoid: Some children with autism spectrum disorder experience digestive distress or behavioral improvements when gluten and casein are removed, though results vary widely (3)(4).

4. Monosodium Glutamate (MSG) & Flavor Enhancers

Why Avoid: MSG is classified as an excitotoxin that may overstimulate the nervous system and worsen sensory sensitivities (5).
Where Found: Soups, instant noodles, chips, seasoning packets.

5. Common Food Allergens & Sensitivity Triggers

Children with ASD often experience higher rates of food sensitivities or intolerances, including:

• Soy
• Corn
• Eggs
• Nuts

Identifying personal triggers through elimination and reintroduction may be helpful when supervised by a healthcare provider (6).

6. Heavy Metals & Environmental Contaminants

Why Avoid: Exposure to heavy metals such as mercury, lead, and aluminum has been linked to neurological concerns and developmental disruption (7).
Where Found: Certain fish, aluminum-based personal care products, foil-packaged foods.

7. Foods With Pesticide Residues

Why Avoid: Some pesticides act as neurotoxins and may negatively affect sensitive nervous systems (7).
Better Alternatives: Organic produce or thorough washing and peeling.

8. Harsh Chemicals in Personal Care & Household Products

Children with autism often have heightened sensory sensitivities, making personal care products a frequent trigger.

Skincare ingredients to avoid for children include:

• Fragrance/Parfum: Often contains hormone-disrupting phthalates
• Sulfates (SLS, SLES): Can irritate skin and scalp
• Parabens: Linked to hormone disruption
• Formaldehyde releasers: Common preservatives in shampoos and soaps

These ingredients may cause skin irritation, discomfort, or sensory overload.

9. Caffeine & Stimulants

Why Avoid: Even small amounts of caffeine can worsen hyperactivity, anxiety, and sleep issues in children with ASD (6).
Where Found: Chocolate, sodas, teas.

10. Additives in Medications & Supplements

Potential Irritants: Artificial dyes, lactose fillers, gluten, artificial sweeteners
Why Avoid: Hidden additives may trigger sensitivities even when food choices are carefully managed (1)(6).

Practical Tips for Parents

1. Read labels carefully on foods, medications, and personal care products
2. Use elimination and reintroduction strategies with professional guidance
3. Choose clean brands to reduce daily exposure to irritants
4. Introduce changes gradually to avoid stress
5. Individualize choices – what works for one child may not work for another
