WHAT TYPE OF FOOD TO AVOID IN AUTISM?

There is no universally required food to avoid in autism, but some foods may be limited or avoided based on individual sensitivities, medical conditions, or behavioural responses. Here's a breakdown of commonly avoided foods and the rationale behind it:

1. Gluten (wheat, barley, rye)

• Found in: Bread, pasta, cereals, baked goods.
• Why some avoid: Based on the theory that gluten may affect brain function in some individuals with autism (the “leaky gut” hypothesis).
• Evidence: Limited and inconsistent. Some individuals with ASD and GI issues may benefit from a gluten-free diet, but it is not a general recommendation for all.

2. Casein (dairy protein)

• Found in: Milk, cheese, yogurt, cream.
• Why some avoid: Similar to gluten, casein may trigger inflammatory or behavioural responses in some children.
• Evidence: Anecdotal for most; formal elimination should be monitored to avoid calcium and vitamin D deficiencies.

3. Artificial Additives and Preservatives

• Includes: Artificial colours (e.g., Red 40), flavours, sweeteners (aspartame), preservatives (BHA, BHT).
• Why some avoid: Some believe these can worsen hyperactivity or behavioural symptoms.
• Evidence: Stronger in ADHD than autism, but some parents report improvements.

4. High-Sugar Foods and Beverages

• Found in: Soda, candy, cookies, sweetened cereals.
• Why some avoid: May exacerbate hyperactivity or energy swings; can contribute to obesity and poor diet quality.
• Evidence: General health concern rather than autism-specific.

5. Processed and Junk Foods

• Found in: Chips, fast food, microwave meals.
• Why some avoid: Often preferred by selective eaters but lack nutritional value.
• Concern: High in sodium, unhealthy fats, and low in essential nutrients.

6. Food Allergens and Intolerances

• Includes: Eggs, nuts, soy, etc.
• Why some avoid: True allergies or intolerances (e.g., lactose intolerance) may be more common in some individuals with autism.
• Note: These should be medically diagnosed before restriction.

7. Foods that Cause GI Discomfort

• Includes: High FODMAP foods (beans, onions, certain fruits) or foods high in lactose or fiber.
• Why some avoid: If there are significant GI symptoms like bloating, diarrhea, or gas.

Important Notes:

• Avoiding major food groups without supervision can lead to nutrient deficiencies.
• Always involve a registered dietitian or physician before starting elimination diets.
