There is no strong scientific evidence that all autistic children must avoid dairy or eggs. Many autistic children eat both daily with no issues. Remove a food only if your child has a diagnosed allergy or you notice a clear, repeatable change in behaviour or digestion after eating it — ideally confirmed with your paediatrician, not just a WhatsApp forward. If you do need alternatives, calcium can come from ragi, sesame, leafy greens, nuts and seeds; protein from dals, soya, paneer alternatives, and meats. A food-intolerance work-up ordered by a doctor is more reliable than blanket elimination diets, which can cause nutritional gaps in already-picky eaters.
