Study reveals vitamin D and iron deficiencies in children with autism
Nearly 40% of children with autism may lack essential nutrients like vitamin D and iron, which are crucial for their growth and development.

A growing body of research is shedding light on the hidden health challenges faced by children with autism and the latest findings point to nutrition.
A study from Singapore has revealed that nearly 40% of autistic children may be deficient in vitamin D and iron, nutrients that play a vital role in growth, brain function, and overall wellbeing.
Children on the autism spectrum are often known to be selective eaters, sometimes avoiding certain textures, colours, or flavours altogether.
Previous studies suggest they are around five times more likely to be “picky eaters” than their neurotypical peers, which can make it difficult to maintain a balanced diet.
Until now, however, the extent of nutritional deficiencies in this group has been less well understood.
The Singapore-based research, published in the journal “Nutrients”, assessed the diets of more than 240 children.
It found that more than 15% of those with iron deficiency had developed anaemia, a condition where the body doesn’t produce enough healthy red blood cells to carry oxygen efficiently.
Experts called the findings important and urged parents and health authorities to consider introducing routine nutritional screenings for children with autism.
The authors said: “Vitamin D and iron deficiencies were commonly detected in this study population of children with autism.
“Identifying the presence of such deficiencies and pursuing appropriate treatment for these can result in improvements in the overall health and development in these children.”
Vitamin D, often called the “sunshine vitamin”, is essential for bone strength, immune support, and mental health, while iron plays a key role in energy levels and cognitive development.
Both are particularly critical during childhood.
The study adds to global concerns that many children, not only those with autism, may not be meeting their nutritional needs.
According to UNICEF, deficiencies in iron and vitamin D remain among the most common micronutrient issues worldwide, with long-term consequences if left unaddressed.
Early intervention, the researchers stressed, could make a long-term difference in children’s development and quality of life.
